| 1 | 四川盆地及邻区晚震旦世古地理与构造—沉积环境演化显示文摘利用最新的地震资料、探井资料及区域地质资料等,结合前人的研究成果,建立四川盆地及邻区晚震旦世区域地层格架,编制晚震旦世各沉积时期构造—沉积环境图,并探讨构造—沉积演化过程。研究认为,四川盆地及邻区晚震旦世构造—沉积环境展布受基底构造限制,并具一定继承性。晚震旦世开始大规模的碳酸盐岩台地沉积,整体来看自西向东海域环境由浅变深,由古陆过渡至碳酸盐岩台地、向东至台地边缘—斜坡沉积泥质岩,至深水盆地相沉积硅质岩,各相带总体呈南西—北东走向。上震旦统灯影组一段 ( 简称灯一段) 沉积时期—灯二段沉积中期为填平补齐沉积充填过程; 灯二段沉积时期末—灯三段沉积期在克拉通内拗陷盆地基础上初步形成了平缓的克拉通内部隆起; 灯四段沉积时期伴随着海平面的下降,碳酸盐岩台地边界整体向东迁移。灯二、灯四段沉积时期末受桐湾运动两期抬升的影响,川中部分地区形成岩溶不整合面,盆地西部灯三、灯四段遭受强烈剥蚀。灯影组是四川盆地及邻区重要的油气储集层。 | 李英强 何登发 文竹 | 2013 | 古地理学报2013，15，2： | 55 |
| 2 | 四川盆地震旦-寒武系油气成藏的Re-Os年代学约束显示文摘四川盆地震旦-寒武系储层具有万亿立方米以上的油气地质储量,具有广阔的勘探前景.复杂的地质条件及多期次构造作用限制了对其油气成藏演化过程的精细刻画.近年来,流体包裹体^(40)Ar/^(39)Ar和烃类Re-Os同位素定年等新技术在油气成藏研究中表现出良好的潜力和广泛的应用前景.针对四川盆地深部油气成藏演化的定量解析这一问题,在总结前人对震旦-寒武系油气成藏演化地质分析的基础上,结合近期对川中威远气田、川西龙门山矿山梁古油藏和川北米仓山古油藏中沥青Re-Os同位素的定年结果,认为四川盆地震旦-寒武系油气存在~450Ma、205~162Ma两期成藏作用,其中天然气藏形成的关键时期为205~162Ma.还指出了Re-Os同位素分析在定量解析油气演化研究中需要解决的关键问题,并认为烃类的Re-Os同位素定年将会推动我国成藏年代学的发展,促进诸如四川盆地等复杂地质条件深层油气成藏过程和成藏机理的研究. | 沈传波 葛翔 白秀娟 | 2019 | 地球科学2019，44，3： | 13 |
| 3 | 川中古隆起北斜坡不同地区灯影组天然气差异及其影响因素——以蓬探1井和中江2井为例显示文摘川中古隆起北斜坡灯影组具有良好的勘探潜力,是四川盆地天然气勘探重要的后备战略接替区。北斜坡地区灯影组天然气为以CH_(4)为主的干气,天然气内部δ^(13)C_(C_(2)H_(6))、CO_(2)含量及δ^(13)C_(CO_(2))等存在明显差异,天然气组分及同位素差异因素的分析对深化灯影组天然气成藏演化过程的研究具有重要意义。本文基于北斜坡两口典型探井(蓬探1井和中江2井)灯影组天然气组分及不同组分同位素的分析,结合岩芯、岩石薄片的观察及储层固体沥青碳同位素、显微结构的分析,深入剖析了造成北斜坡区典型探井天然气差异的原因。受硫酸盐热化学还原反应(TSR)作用的影响,北斜坡地区灯影组天然气中存在较高含量的H2S,储层沥青碳同位素较烃源岩明显偏轻,C_(2)H_(6)碳同位素偏重。川中古隆起北斜坡区灯影组储层受过热液流体的影响,储层内黄铁矿、闪锌矿、方铅矿等热液矿物组合发育,储层沥青发育中—粗粒镶嵌、纤维状等显微结构。热液活动为TSR作用提供了丰富的硫源,热液活动的强度是控制TSR反应强度的关键。强烈的TSR作用导致了天然气组分的变化及C_(2)H_(6)、CO_(2)碳同位素的增加,是造成不同区域天然气差异的原因。 | 朱联强 柳广弟 宋泽章 赵文智 田兴旺 戴鑫 王云龙 杨岱林 李强 江林 李成海 胡丽 | 2021 | 石油科学通报2021，6，3： | 11 |
| 4 | 川东南志留系小河坝组致密砂岩储层孔隙结构显示文摘针对川东南地区下志留统小河坝组致密砂岩储层,利用铸体薄片、扫描电镜、物性测试、高压压汞、恒速压汞等技术手段,结合前人的研究成果,对储层微孔隙类型和结构特征进行研究。结果表明:储层演化程度较高,原生孔隙发育较少,次生溶孔占总孔隙的80%,包括微米级粒间溶孔、微米-纳米级粒内溶孔和杂基溶孔;高压压汞屏蔽了半径较大的孔隙,表征的孔喉半径为0.01~1.26μm,半径>0.1μm的喉道所占比例<10%;恒速压汞测试表明,渗透率不同的样品孔隙半径大小及分布范围相近,孔隙半径主要集中在145μm左右,分布范围为40~260μm;喉道半径大小相差悬殊,且分布范围较大,为0.1~2.7μm。高压压汞和恒速压汞结合表征小河坝组致密砂岩的孔隙半径为0.01~260μm,喉道半径为0.01~2.7μm;致密储层孔隙度主要受单位体积有效孔隙数量、有效孔隙半径大小的影响,而渗透率主要受控于有效喉道半径的大小和分布,储层物性的差异则是这些孔-喉结构参数共同影响的综合体现。 | 王良军 张文凯 胡晓文 罗彦萍 程立雪 | 2019 | 成都理工大学学报(自然科学版)2019，46，1： | 7 |

| 6 | Sequence architecture and sedimentary characteristics of a Middle Jurassic incised valley,western Sichuan depression,China显示文摘The Middle Jurassic Shaximiao Formation encompasses tens of meters of thick lowstand meandering valley(LMV) strata in the western Sichuan foreland basin. Ancient LMVs newly discovered in this area were further studied based on sequence stratigraphy and seismic sedimentology. The aim of the present study was to investigate the sedimentary characteristics,sequence architecture, and the controls on LMV deposition in this tectonically active basin using field survey data, seismic sections, seismic amplitude imaging, core description, and comprehensive application of drilling data. The results show the following:(1) Three regional sequence boundaries and two flooding surfaces were recognized, and the Shaximiao Formation was divided into two-third-order sequences and four systems tracts.(2) Three sedimentary facies associations were identified: incised valley-fill, tributary channel, and overbank facies. Incised valleys are 5–17 km wide, 20–60 m deep and traceable for 120 km along their axes.(3) In the downstream segment, the role of tectonism gradually diminishes, and periodic base-level changes control the form and evolution of the incised valleys. Three types of LMVs—A1, A2, and A3—developed with changes in base level(lake level); of these types, the base level of the A3 LMV was likely the lowest. | Jun-Long Liu Wei Yin You-Liang Ji Tian-Yun Wang Fu-Xiang Huang Hai-Yue Yu Wen-Shu Li | 2018 | Petroleum Science2018，15，2： | 2 |
| 7 | Hydrocarbon Accumulation Process in the Marine Strata in Jianghan Plain Area, Middle China显示文摘Marine strata in the Jianghan Plain area are widely distributed with a total depth of more than 8,000 m from the Upper Sinian to the Middle Triassic. Six reservoir caprock units, named Z–∈2, ∈2–O, S, D–C, P and T1, can be identified with each epoch. The geology, stratigraphy, drilling, oil testing and other basic data as well as the measured inclusion and strontium isotope data in the study area are used in the analysis of the formation and evolution process of marine petroliferous reservoirs in the Jianghan Plain area. This study aims to provide a scientific basis for the further exploration of hydrocarbons in the Jianghan Plain and reduce the risks by analyzing the key factors for hydrocarbon accumulation in the marine strata. Our findings show that in the Lower Palaeozoic hydrocarbon reservoir, oil/gas migration and accumulation chiefly occurred in the early period of the Early Yanshanian, and the hydrocarbon reservoir was destroyed in the middle–late period of the Early Yanshanian. In the Lower Triassic–Carboniferous hydrocarbon reservoir, oil/gas migration and accumulation chiefly occurred in the Early Yanshanian, and the hydrocarbon reservoir suffered destruction from the Late Yanshanian to the Early Himalayanian. The preservation conditions of the marine strata in the Jianghan Plain area have been improved since the Late Himalayanian. However, because all source beds have missed the oil/gas generation fastigium and lost the capacity to generate secondary hydrocarbon, no reaccumulation of hydrocarbons can be detected in the study area's marine strata. No industrially exploitable oil/gas reservoir has been discovered in the marine strata of Jianghan Plain area since exploration began in 1958. This study confirms that petroliferous reservoirs in the marine strata have been completely destroyed, and that poor preservation conditions are the primary factor leading to unsuccessful hydrocarbon exploration. It is safely concluded that hydrocarbon exploration in the marine strata of the study area is quite risky. | XU Guosheng ZHANG Lijun GONG Deyu WANG Guozhi YUAN Haifeng LI Changhong HU Xiaofeng | 2014 | Acta Geologica Sinica(English Edition)2014，88，3： | 0 |
