| 1 | Characteristics and accumulation mechanism of tight sandstone gas reservoirs in the Upper Paleozoic, northern Ordos Basin, China显示文摘The Ordos Basin is a significant petroliferous basin in the central part of China.The Carboniferous and Permian deposits of transitional and continental facies are the main gas-bearing layers in the north part of the basin.The Carboniferous and Permian natural gas reservoirs in the northern Ordos Basin are mainly tight sandstone reservoirs with low porosity and low permeability,developing lots of 'sweet spots' with comparatively high porosity and permeability.The tight sandstones in the study area are gas-bearing,and the sweet spots are rich in gas.Sweet spots and tight sandstones are connected rather than being separated by an interface seal.Sweet spot sand bodies are vertically and horizontally overlapped,forming a large gas reservoir group.In fact,a reservoir formed by a single sweet spot sand body is an open gas accumulation.In the gentle dipping geological setting and with the source rocks directly beneath the tight reservoirs over a large area,the balance between gas charging into tight reservoirs from source rocks and gas loss from tight reservoirs through caprock is the key of gas accumulation in tight sandstones.Both the non-Darcy flow charging driven by source-reservoir excess pressure difference and the diffusion flow charging driven by source-reservoir gas concentration difference play an important role in gas accumulation.The results of mathematical modeling indicate that the gas accumulation cannot be formed by just one of the above mechanisms.The diffusion of gas from source rocks to reservoirs is a significant mechanism of tight sandstone gas accumulation. | Liu Guangdi Sun Mingliang Zhao Zhongying Wang Xiaobo Wu Shenghe | 2013 | Petroleum Science2013，10，4： | 16 |
| 2 | MoS_(2)-Decorated/Integrated Carbon Fiber:Phase Engineering Well-Regulated Microwave Absorber显示文摘Phase engineering is an important strategy to modulate the electronic structure of molybdenum disulfide(MoS_(2)).MoS_(2)-based composites are usually used for the electromagnetic wave(EMW)absorber,but the effect of different phases on the EMW absorbing performance,such as 1T and 2H phase,is still not studied.In this work,micro-1T/2H MoS_(2) is achieved via a facile one-step hydrother-mal route,in which the 1T phase is induced by the intercalation of guest molecules and ions.The EMW absorption mechanism of single MoS_(2) is revealed by presenting a comparative study between 1T/2H MoS_(2) and 2H MoS_(2).As a result,1T/2H MoS_(2) with the matrix loading of 15%exhibits excellent microwave absorption property than 2H MoS_(2).Furthermore,taking the advantage of 1T/2H MoS_(2),a flexible EMW absorbers that ultrathin 1T/2H MoS_(2)grown on the carbon fiber also performs outstanding performance only with the matrix loading of 5%.This work offers necessary reference to improve microwave absorption performance by phase engineering and design a new type of flexible electromagnetic wave absorption material to apply for the portable microwave absorption electronic devices. | Jing Yan Ying Huang Xiangyong Zhang Xin Gong Chen Chen Guangdi Nie Xudong Liu Panbo Liu | 2021 | Nano-Micro Letters2021，13，7： | 5 |
| 3 | Microbial alteration of natural gas in Xinglongtai field of the Bohai Bay Basin, China显示文摘Xinglongtai field has been an important petroleum-producing area of Liaohe Depression for 30 years. Oil exploration and production were the focus of this field, but the gas was ignored. This study examined twenty five gas samples with the purpose of determining the gas genetic types and their geochemical characteristics. Molecular components, stable carbon isotopic compositions and light hydrocarbons were also measured, and they proved that microbial activity has attacked some of the gas components which resulted in unusual carbon isotopic distributions. Propane seems to be selectively attacked during the initial stage of microbial alteration, with abnormally lower con-tent compared to that of butane as well as anomalously heavy carbon isotope. As a consequence, the carbon isotopic distribution among the gas components is partially reverse, as δ13C1<δ13C2<δ13C3>δ13C4. Besides, n-alkanes of C3+ gas components are preferentially attacked during the process of microbial alteration. This is manifested that n-alkanes are more enriched in 13C than corresponding iso-alkanes. As a result, the concentrations of n-alkanes be-come very low, which may be misleading in indentifying the gas genetic types. As to four gas samples, light hydro-carbon compositions display evidence for microbial alteration. The sequence of hexane isomers varies obviously with high content of 2,3-DMC4, which indicates that they have been in the fourth level of extensively bacterial al-teration. So the geochemical characteristics can be affected by microbial alteration, and recognition of microbial alteration in gas accumulations is very important for interpreting the natural gas genetic types. | YANG Weiwei LIU Guangdi GONG Yaojin FENG Yuan | 2012 | Chinese Journal Of Geochemistry2012，31，1： | 4 |
| 4 | Limitation of fault-sealing and its control on hydrocarbon accumulation——An example from the Laoyemiao Oilfi eld of the Nanpu Sag显示文摘Based on previous studies on the internal structures of fault belts, the fault belts in the Laoyemiao Oilfi eld of the Nanpu Sag can be divided into three units, a crushed zone, an upper induced fracture zone and a lower induced fracture zone according to the log response characteristics. The upper induced fracture zone is characterized by the development of pervasive fractures and has a poor sealing or non-sealing capability. It therefore can act as pathways for hydrocarbon migration. The lower induced fracture zone consists of fewer fractures and has limited sealing capability. The crushed zone has a good sealing capability comparable to mudstone and can thus prevent lateral migration of fluid. Through physical modeling and comparing laboratory data with calculated data of oil column heights of traps sealed by faults, it is concluded that the fault-sealing capability for oil and gas is limited. When the oil column height reaches a threshold, oil will spill over from the top of reservoir along the lower induced fracture zone under the action of buoyancy, and the size of reservoir will remain unchanged. Analysis of the formation mechanisms of the fault-sealed reservoirs in the Nanpu Sag indicated that the charging sequence of oil and gas in the reservoir was from lower formation to upper formation, with the fault playing an important role in oil and gas accumulation. The hydrocarbon potential in reverse fault-sealed traps is much better than that in the consequent fault-sealed traps. The reverse fault-sealed traps are favorable and preferred exploration targets. | Jiang Zhenxue Dong Yuexia Li Hongyi Liu Luofu Liu Guangdi Li Xiaoying | 2008 | Petroleum Science2008，5，4： | 4 |
| 5 | Dynamic Systems of Petroleum Accumulation in the Nanpu Depression,Bohai Bay Basin,China显示文摘为石油累积和分发的理解区分石油累积(DSPA ) 的动态系统是重要的。根据形成压力框架,石油的基因类型和水管系统的特征,石油累积的三个动态系统在 Nanpu 消沉在垂直侧面被识别, Bohai 海湾盆。更深的 DSPA (到 Es2 的包括的形成 Es3 ) 是有高过压、高度成熟的自我采购的油的一个封上的系统。大多数在系统的原油近来在时期积累了渐新世(23.5 妈) 和迟了的上新世(2.4 妈) 。中间的 DSPA (到 Ed1 的包括的形成 Es1 ) 是 overpressured 有成熟或降低成熟的自我采购的油的封上一半的系统。在系统的油的累积也发生在迟了的渐新世(23.5 妈) 和迟了的上新世(2.4 妈) 。更浅的 DSPA (到 Q 的包括的形成 Ed2 ) 是有从中间的系统的降低成熟的采购侨民的油的一个静水力学的系统。在这个系统以内的油仅仅在迟了的上新世时期积累了。在更浅的系统的油沿着 sandbodies 由侧面的移植在中间的系统从先前积累的油沿着差错垂直地移居了,而在更深的系统的石油累积主要从由沿着 sandbodies 并且很少的侧面的移植的本身从系统移植了的系统被导出。在这种情况中,看起来更深的系统是除了另外的二个证明有利系统的更潜在的探索前景。 | LIU Guangdi SUN Mingliang ZHANG Zhihuan DONG Yuexia | 2010 | Acta Geologica Sinica(English Edition)2010，84，5： | 3 |
| 6 | Rapid hydrocarbon accumulation mechanism in later period in Kelasu thrust belt in Kuqa depression显示文摘Based on the analyses of generation, migration and accumulation of oil and gas in the structures of Kela 1, Kela 2 and Kela 3 in Kasangtuokai anticlinal belt using a series of geological and geochemical evidence, this paper proposes that the rapid rate of hydrocarbon generation, main drain path for over-pressured fluid flow and converging conduit system are indispensable conditions for the rapid, late-stage gas accumulation in the Kelasu thrust belt in the Kuqa depression. Due to structural over-lapping and the resultant rapid burial, the maturity of the source rocks had been increased rapidly from 1.3 to 2.5% Ro within 2.3 Ma, with an average rate of Ro increase up to 0.539% Ro/Ma. The rapid matura-tion of the source rocks had provided sufficient gases for late-stage gas accumulation. The kelasu structural belt has a variety of faults, but only the fault that related with fault propagation fold and cut through the gypsiferous mudstone cap could act as the main path for overpressured fluid release and then for fast gas accumulation in low fluid potential area. All the evidence from surface structure map, seismic profile explanation, authigenic kaolinite and reservoir property demonstrates that the main drain path related with faults for overpressured fluid and the converging conduit system are the key point for the formation of the giant Kela 2 gas field. By contrast, the Kela 1 and Kela 3 structures lo-cated on both sides of Kela 2 structure, are not favourable for gas accumulation due to lacking con-verging conduit system. | ZOU HuaYao WANG HongJun HAO Fang LIU GuangDi ZHANG BaiQiao | 2007 | Science China Earth Sciences2007，50，8： | 3 |

| 9 | Structural Characteristics and their Significance for Hydrocarbon Accumulation in the Northern Slope of the Central Sichuan Paleo-uplift显示文摘Based on 2D and 3D seismic data,the latest drilling data and field outcrop data of the northern slope of the Central Sichuan paleo-uplift,the structural analysis method is used to analyze unconformity development characteristics and fault characteristics during the key structural transformation period,discussing the influence of the structural characteristics on the hydrocarbon accumulation of deep carbonate rocks.The results show that:(1)The two key unconformities of the Tongwan and Caledonian periods were primarily developed in deep carbonate rocks.Firstly,Tongwan’s unconformities are characterized by regional disconformities between the second and third members of the Dengying Formation,the top formation of the Sinian and the lower Cambrian,strips of which zigzag through the north and south sides of the study area.Secondly,the Caledonian unconformity is characterized by a regional unconformable contact between the lower Permian and the ower Paleozoic strata.From NE to SW,the age of the strata,which were subject to erosion,changes from new to old,the denudation distribution showing as a nose-shaped structure which inclines towards the ENE.(2)Boundary fault and transtensional strike-slip faults developed in the Sinian to Paleozoic strata.In profile,there are three types of structural styles:steep and erect,flower structures,’Y’and reversed’Y’type faults.In plane view,the Sinian developed extensional boundary faults extending in an almost NS direction,strike-slip faults developing and extending linearly in approximately EW,WNW and NE strikes in the Cambrian,with characteristically more in the south and less in the north.(3)The faults in the northern slope show obvious zonal deformations in transverse view as well as significant stages and stratified activity in a longitudinal direction.Among them,the activity of faults in the Sinian was the strongest,followed by the activity in the Cambrian period,the activity intensity of faults in the Permian period being the weakest.This fault activity can be divided into four periods:Sinian,Cambrian-Permian,the early Indosinian period and the late Indosinian-Himalayan period,the transtensional strikeslip faults being the products of oblique extensions of pre-existing weak zones in the Xingkai and Emei taphrogenesis,with a particular inheritance in the main faults.(4)Combined with hydrocarbon accumulation factors,it is considered that the epigenetic karstification of the Tongwan and Caledonian unconformities in the northern slope controlled the formation and distribution of carbonate karst reservoirs over a large area,also acting as a good pathway for oil and gas migration.The extensional faults developed at the margin of the NS trending rift,controlling the sag-platform sedimentary pattern in the Dengying Formation of the Sinian.Strike-slip faults in NE,WNW and ENE directions may control the microgeomorphological pattern inside the platform and intensify the differential distribution of grain beach facies.The multi-stage hereditary activity of strike-slip faults not only improved the porosity and permeability of the reservoirs,but also acted as the main channel of oil and gas migration,providing favorable conditions for the development of the current multi-layer gasbearing scenario in the northern slope of the Central Sichuan Basin. | TIAN Xingwang LIU Guangdi LUO Bing YANG Yu WEN Long ZHANG Benjian CHEN Xiao SU Guiping SONG Zezhang PENG Hanlin ZHOU Gang YAN Wei YANG Dailin WANG Yunlong SUN Yiting DOU Shuang | 2022 | Acta Geologica Sinica(English Edition)2022，96，4： | 2 |
| 10 | The special sealing mechanism of caprock for Quaternary biogenetic gas in Sanhu area,Qaidam Basin,China显示文摘The Quaternary biogenetic gas reservoirs in the east of Qaidam Basin have many characteristics such as late forming time,shallow burial depth,low diagenetic grade,high porosity and high permeability and so on.It cannot be considered as caprock according to the traditional evaluation criterion.However, the large scale and high efficient biogenetic gas reservoirs of the Qaidam Basin are really formed under these kinds of caprocks,so it does have some specialty in its sealing mechanism.Aiming at the special sealing mechanism,some simulating experiments have been done.The research results show that the sealing ability of biogenetic gas caprock is related with water saturation,the caprock that is saturated with salt water can effectively block seepage and diffusion.Furthermore,the multiple reservoir-caprock groups have accumulated sealing effect,causing the formation of big gas fields.The evaluation method with traditional caprock parameters cannot be adopted in evaluating the study area. | LI Jian 1 ,YAN QiTuan 1 ,ZHANG Ying 1 ,LIU GuangDi 2 &WANG XiaoBo 1 1 Research Institute of Petroleum Exploration and Development-Langfang,Langfang 065007,China 2 University of Petroleum,Beijing 102249,China | 2008 | Science China Earth Sciences2008，51，S1： | 2 |
| 11 | Two highly efficient accumulation models of large gas fields in China显示文摘Based on reserve abundance, large gas fields in China can be divided into two types: type one of high abundance large gas fields, dominated by structural gas reservoirs; type two of low abundance large gas fields, dominated by stratigraphic and lithologic gas reservoirs. The formation of these two types of large gas fields is related to the highly efficient accumulation of natural gas. The accumulation of high abundance gas fields is dependent on the rapid maturation of the source kitchen and huge residual pressure difference between the gas source kitchen and reservoir, which is the strong driving force for natural gas migration to traps. Whereas the accumulation of low abundance gas fields is more complicated, involving both volume flow charge during the burial stage and diffusion flow charge during the uplift stage, which results in large area accumulation and preservation of natural gas in low porosity and low permeability reservoirs. This conclusion should assist gas exploration in different geological settings. | Wang Hongjun Bian Congsheng Liu Guangdi Sun Mingliang Li Yongxin | 2014 | Petroleum Science2014，11，1： | 2 |

| 14 | Evaluation of oil sands resources──A case study in the Athabasca Oil Sands,NE Alberta,Canada显示文摘Oil sands are the most important of the oil and gas resources in Canada. So the distribution and evaluation of oil sands form a critical basis for risk investment in Canada. Distribution of oil sands resources is severely controlled by the reservoir heterogeneity. Deterministic modeling is commonly used to solve the heterogeneity problems in the reservoir, but rarely used to evaluate hydrocarbon resources. In this paper, a lithofacies based deterministic method is employed to assess the oil sands resources for a part of a mining project in northern Alberta. The statistical analysis of Dean Stark water and oil saturation data and study of the core description data, regional geology and geophysical logs reveal that the lithofacies in the study area can be classified into reservoir facies, possible reservoir facies and non-reservoir facies. The indicator krigging method is used to build a 3D lithofacies model based on the classification of sedimentary facies and the ordinary krigging method is applied to petrophysical property modeling. The results show that the krigging estimation is one of the good choices in oil sand resources modeling in Alberta. Lithofacies-grade based modeling may have advantages over the grade-only based modeling. | Yin Pengfei Liu Guangdi Liu Yingqi Liu Chenglin Liu Wenping | 2013 | Petroleum Science2013，10，1： | 1 |

| 19 | Performance Study and Multi-Objective Optimization of a Two-Temperature CO_(2) Refrigeration System with Economizer Based on Energetic, Exergetic and Economic Analysis显示文摘A two temperature CO_(2) refrigeration system with economizer is proposed and compared with the traditional dual-temperature CO_(2) refrigeration system based on energy consumption,exergy and economic analysis.Using genetic algorithm multi-objective optimization method,taking the COP,exergy loss and total economic cost as the objective functions to find the best design conditions of the two systems.The Pareto fronts are obtained at different ambient temperatures.Technique for order preference by similarity to an ideal solution decision-making method is adopted to determine the optimum state points.The simulation results show that when operating at different ambient temperatures,the introduction of economizer can improve COP,reduce exergy loss and the overall economic cost rate of the two-temperature CO_(2) refrigeration system.In addition,economic analyses take the impact of carbon dioxide emission cost and electricity price into consideration.The results indicate that with the increase of CO_(2) emission cost and electricity price,the hourly economic cost of both systems increases,but the hourly economic cost of the two-temperature CO_(2) refrigeration system with economizer system is always lower than that of conventional two-temperature CO_(2) refrigeration system. | LIU Guangdi ZHAO Hongxia WANG Zheng ABDULWAHID Alhasan Ali HAN Jitian | 2022 | Journal of Thermal Science2022，31，5： | 0 |
| 20 | Oil source and accumulation in the overthrust belt in the Ke-Bai region,Junggar Basin,west China显示文摘The region around the Karamay-Baikouquan(Ke-Bai) overthrust belt is the richest in hydrocarbon accumulation in the Junggar Basin. Previous research has indicated that oil in the region came from the Fengcheng Formation in the Mahu Depression to the northeast of the region,but the oil distribution around the Mahu Depression is remarkably uneven. Large amounts of oil have been found in the Ke-Bai overthrust belt to the west of the depression and only some small oilf ields have been discovered in the eastern margin of the depression. This uneven distribution revealed that the oil source of the Ke-Bai region might not be from the Mahu Depression. The oil type distribution and the oil migration pattern revealed in this paper showed that there may be another oil source under the Karamay overthrust. Based on geochemical data,the oil was classifi ed into two types from the sterane and terpane characteristics. Type A oil was mainly distributed in the Huwan area and blocks V and VIII of the Karamay Oilfi eld in the southern part of the region,while type B oil was mainly distributed in the Baikouquan Oilfield in the northern part of the region. In addition,oil migration pathways and direction were determined by the values of diasterane /regular sterane and C30 moretane /C30 hopane ratios. It is shown that the oil of Huwan area on the hanging wall of the overthrust was mainly charged along the overthrust fault surfaces and then migrated to the west,whereas the oil in blocks V and VIII on the foot wall of the overthrust came from the Mahu Depression in the east. As a result,there may be at least two hydrocarbon source kitchens in the study area. The hydrocarbons in the blocks V and VIII on the footwall of the overthrust belt and in the Baikouquan Oilfield mainly came from the Fengcheng Formation in the Mahu Depression,and the hydrocarbons in the Huwan area on the hanging wall of the overthrust belt may come from another hydrocarbon source kitchen below the overthrust. This recognition indicates that there is substantial exploration potential in the deep Carboniferous strata on the hanging wall of the overthrust belt. | Liu Guangdi Gao Gang Huang Zhilong Yang Haifeng | 2010 | Petroleum Science2010，7，1： | 0 |
