| 1 | The role of provenance in the diagenesis of siliciclastic reservoirs in the Upper Triassic Yanchang Formation,Ordos Basin,China显示文摘A better understanding of the controls on reservoir quality has become essential in the petroleum exploration in recent years.Determining the original composition of the sediment framework is important not only for paleogeographic reconstructions,but it is also vital for predicting the nature of physical and chemical diagenesis of the potential reservoirs.Depositional setting and diagenesis are important factors in controlling the type and quality of most siliciclastic reservoirs.We studied the Upper Triassic Chang 8 and 6 members,where the relationship between sediment provenance and diagenesis was examined.The study attempts to clarify sediment provenance and post-depositional diagenetic modifications of the sandstones through systematic analytical methods including petrographic macro-and microscopic analysis of grain and heavy mineral types,and measurements of the palaeocurrent direction of the Yanchang Formation sediments in the outcrops in order to determine the provenance of the studied sediments.Furthermore,the relationship between framework grains,pore types and diagenesis of the sediments was analyzed by thin section petrographic characterization using a polarizing microscope.Additionally,a JEOL JSM-T330 scanning electron microscope(SEM) equipped with a digital imaging system was used to investigate the habits and textural relationships of diagenetic minerals.On the basis of our results,we believe that sediment provenance is a significant factor which controls the type and degree of diagenesis which may be expected in sandstones.In the Chang 8 and 6 members,the formation of chlorite rims and laumontite cement was observed where volcanic rock fragments constitute a large part of the framework grains.Furthermore,high biotite content provides abundant iron and magnesium and enables the formation of chlorite rims due to biotite hydrolysis.In addition,ductile deformation of biotite leads to strong mechanical compaction of the sediments.Conversely,high feldspar content diminishes the degree of mechanical compaction,however the dissolution of feldspar minerals in sandstones is commonly observed.Apart from feldspars,quartz and other rigid framework grains highly control the degree of mechanical compaction during the initial stage of burial(0-2 km). | Ding Xiaoqi Han Meimei Zhang Shaonan | 2013 | Petroleum Science2013，10，2： | 16 |

| 13 | Reservoir formation mechanism analysis and deep high-quality reservoir prediction in Yingcheng Formation in Longfengshan area of Songliao Basin, China显示文摘Although commercial gas flow was produced in several wells with recent years'exploration of Longfengshan area in Changling fault sag,the formation mechanism and controlling factors for high-quality reservoirs still remained undefined.Here,the Yingcheng tight gas reservoirs of Longfengshan area are used as an example to characterize high-quality reservoir formation mechanism and distribution rules.Based on the thin section,SEM,X-ray diffraction,computed tomography(CT)scanning,burial history,constant-rate mercury penetration and physical properties testing,formation mechanism and controlling factors for high-quality reservoirs were analyzed.Results show the following characteristics.First,the reservoir is dominated by chlorite and laumontite cements,and compaction is the most important factor to control reservoir physical properties.According to this,the reservoir can be divided into compacted tight sandstones,chlorite-cemented sandstones and laumontite-cemented sandstones.Second,the high-quality reservoirs are formed due to early extensive laumontite precipitation and the later dissolution of laumontite by organic acid.Meanwhile,it is found that the distribution of cementation and dissolution exhibits some regulations in sedimentary facies,and the distribution is mainly effected and controlled by the lake water and charging of fresh water.Besides,the distribution model of various types of sandstones was established.Studies over diagenesis and sedimentary facies reveal that the high-quality laumontite-cemented sandstones exist in the outside subaqueous fan-delta of the deep sag in Longfengshan area.These findings have been validated by recent exploration wells which obtained high industrial gas flow. | Yongmei Zhang Xiaoqi Ding Peng Yang Yan Liu Qi Jiang Shaonan Zhang | 2016 | Petroleum2016，2，4： | 1 |

| 16 | The effect of thermal fluid derived from mud diapir on sandstone reservoirs in the Yinggehai Basin, South China Sea显示文摘The underground thermal fluid is one of the significant factors controlling the formation and quality of reservoirs.The Huangliu Formation(N_(1)h)in YF1 area of the central depression belt in the Yinggehai Basin,South China Sea,is characterized by intense thermal fluid activities related to mud diapir and large-scale shallow-water gravity flow deposits.The multi-episodic invasion of high-temperature and CO_(2)-rich thermal fluid into the formation induces complex water-rock reaction during diagenetic pro-cess,providing a preferable investigation opportunity for revealing how thermal fluid affects reservoir quality.This study characterizes the reservoirs in the formation through core and thin section analyses as well as physical property test.The reservoirs are dominated by fine-grained sandstone characterized by medium porosity(15.2-21.3%)and lower permeability(0.56-15.75mD).Based on an analysis of casting thin section,cathode luminescence(CL),scanning electron microscope(SEM),carbon and oxygen isotope,inclusion test,and electron-probe microanalysis(EPMA),we systematically investigate the diagenetic patterns and pore evolution process for the reservoirs in the formation.The episodic invasion of thermal fluid occurred approximately 0.4 Ma ago plays an important role in controlling reservoir development:The CO_(2)-rich formation water induces massive late-stage dissolution,resulting in a higher proportion of dissolved pores(38.7-46.4%),which improves the porosity of reservoirs at a depth of 2600-3100 m.Nevertheless,the late dissolution together with carbonate cementation occurred in closed diagenetic system blocks most seepage channels.Furthermore,the relatively high level clay mineral transformation in the YF1 area leads to a higher content of authigenic illite(44-62%)in the formation.Massive authigenic illite severely blocks the pore throats in fine sandstone,reducing permeability.This study offers an insight to the understanding of mud diapir-derived thermal fluid affecting and controlling the quality of reservoirs in some areas of the Yinggehai Basin. | Xiaowei Lv Meiyan Fu Shaonan Zhang Yi Liu Xiaoqi Ding Xianghao Meng Shuai Yin Tengjiao Sun | 2022 | Energy Geoscience2022，3，4： | 0 |
| 17 | Sensitivity of solar greenhouse envelopes to the thermal disfigurements and optimal selection of the thermal insulation quilt显示文摘The objectives of the present work are focused on exploration of the reasons for temperature difference in different envelopes,the sensitivity of envelopes of solar greenhouse to thermal disfigurements and optimal selection of the thermal insulation quilt.Theoretical analysis and derivation are conducted according to the experimental results of surface temperature,convective heat transfer,and heat flux density in different envelopes which with thermal disfigurements of solar greenhouse using heat transfer theory.The results revealed that the difference of intrinsic thermal conductivity and thickness of the envelopes leads to difference in the thermal flux and thus in the surface temperature of different envelopes.Compared with the front roof and back roof,the wall is more sensitive to thermal disfigurements.According to the influence of thermal disfigurements on solar greenhouse temperature,the allowable thermal disfigurements area fraction of front roof and back roof are given.Based on the analysis of heat transfer theory and test results,the work given the expression of the thickness and thermal conductivity of thermal insulation quilt under different outdoor minimum temperatures for optimal selection of thermal insulation quilt based on comprehensive considering factors of the solar greenhouse structure,crop demand,outdoor minimum temperature,and insulation quilt properties.The results of this work give technical criterion for whether the envelopes with thermal disfigurements needs to be repaired or replaced,and it also provides theoretical and technical support for design the solar greenhouse as well as methodological guidance for the optimal selection of the thermal insulation quilt. | Yachen Sun Yao Zhang Chenmeng Zhu Shaonan Xu Bowen Liu Yanfei Cao Changji Zhou Yaqi Zhou Zhirong Zou Encai Bao | 2021 | International Journal of Agricultural and Biological Engineering2021，14，5： | 0 |
| 18 | Mitigation of Optical Multipath Interference Algorithms in IM-DD Transmission System显示文摘This paper aimed to propose two algorithms,DA-M and RF-M,of reducing the impact of multipath interference(MPI)on intensity modulation direct detection(IM-DD)systems,particularly for four-level pulse amplitude modulation(PAM4)systems.DA-M reduced the fluctuation by averaging the signal in blocks,RF-M estimated MPI by subtracting the decision value of the corresponding block from the mean value of a signal block,and then generated interference-reduced samples by subtracting the interference signal from the product of the corresponding MPI estimate and then weighting factor.This paper firstly proposed to separate the signal before decision-making into multiple blocks,which significantly reduced the complexity of DA-M and RF-M.Simulation results showed that the MPI noise of 28 GBaud IMDD system under the linewidths of 1e5 Hz,1e6 Hz and 10e6 Hz can be effectively alleviated. | Huo Jiahao Zhu Jin Zhu Zuqing Zhang Xiaoying Liu Shaonan Tao Jianlong Wei Huangfu | 2024 | China Communications2024，21，4： | 0 |
