The molecular compositions and stable carbon and hydrogen isotopic compositions of natural gas from the Xinchang gas field in the Sichuan Basin were investigated to determine the genetic types. The natural gas is mainly composed of methane （88.99%-98.01%）, and the dryness coefficient varies between 0.908 and 0.997. The gas generally displays positive alkane carbon and hydrogen isotopic series. The geochemical characteristics and gas-source correlation indicate that the gases stored in the 5th member of the Upper Triassic Xujiahe Formation are coal-type gases which are derived from source rocks in the stratum itself. The gases reservoired in the 4th member of the Xujiahe Formation and Jurassic strata in the Xinchang gas field are also coal-type gases that are derived from source rocks in the 3rd and 4th members of the Xujiahe Formation. The gases reservoired in the 2nd member of the Upper Triassic Xujiahe Formation are mainly coal-type gases with small amounts of oil-type gas that is derived from source rocks in the stratum itself. This is accompanied by a small amount of contribution brought by source rocks in the Upper Triassic Ma＇antang and Xiaotangzi formations. The gases reservoired in the 4th member of the Middle Triassic Leikoupo Formation are oil-type gases and are believed to be derived from the secondary cracking of oil which is most likely to be generated from the Upper Permian source rocks.

Nanoscale pore characteristics of the Upper Permian Longtan transitional mudrocks and their equivalent strata Wujiaping Formation marine mudrocks in and around the eastern Sichuan Basin was investigated using field emission scanning electron microscopy(FE-SEM)and low-pressure N2 adsorption experiments.The results indicate that the Upper Permian mudrock is at a mature stage with total organic carbon(TOC)values ranging between 0.47%and 12.3%.The Longtan mudrocks mainly contain vitrinite,and their mineral composition is primarily clay.In contrast,the Wujiaping mudrocks are dominated by sapropelinite and solid bitumen,and their mineral compositions are mainly quartz and a notably high amount of pyrite.The FE-SEM reveals that clay mineral pores and microcracks are the common pore types in the Longtan mudrocks.The specific surface area and pore volume depend on the clay content but are negatively correlated with the TOC.The generation of nanometer pores in the Longtan mudrocks is caused by high clay mineral contents.Meanwhile,the Wujiaping mudrock mainly contains OM pores,and the pore parameters are positively correlated with the TOC.The OM pore development exhibits remarkable differences in the Longtan and Wujiaping mudrocks,which might be related to their sedimentary facies and maceral fractions.Vitrinite and inertinite appear as discrete particles in these mudrocks and cannot generate pores during thermal maturation.Sapropelinite often contains many secondary pores,and solid bitumen with large particles,usually with several pores,is not the major contributor to the pore system of the investigated mudrock.

The Upper Ordovician Wufeng-Lower Silurian Longmaxi shale is widely distributed in the Sichuan Basin and its periphery,which is the key stratum for marine shale gas exploration and development(E&D)in China.Based on sedimentary environment,material basis,storage space,fracability and reservoir evolution data,the reservoir characteristics of the Wufeng-Longmaxi shale and their significance for shale gas E&D are systematically compared and analyzed in this paper.The results show that(1)the depocenter of the Wufeng(WF)-Longmaxi(LM)shale gradually migrates from east to west.The high-quality shale reservoirs in the eastern Sichuan Basin are mainly siliceous shales,which are primarily distributed in the graptolite shale interval of WF2-LM5.The high-quality reservoirs in the southern Sichuan Basin are mainly calcareous-siliceous and organic-rich argillaceous shales,which are distributed in the graptolite shale interval of WF2-LM7.(2)Deep shale gas(the burial depth>3500 m)in the Sichuan Basin has high-ultrahigh pressure and superior physical properties.The organic-rich siliceous,calcareous-siliceous and organic-rich argillaceous shales have suitable reservoir properties.The marginal area of the Sichuan Basin has a higher degree of pressure relief,which leads to the argillaceous and silty shales evolving into direct cap rocks with poor reservoir/good sealing capacity.(3)Combining shale gas exploration practices and impacts of lithofacies,depth,pressure coefficient and brittle-ductile transition on the reservoir properties,it is concluded that the favorable depth interval of the Wufeng-Longmaxi shale gas is 2200~4000 m under current technical conditions.(4)Aiming at the differential reservoir properties of the Wufeng-Longmaxi shale in the Sichuan Basin and its periphery,several suggestions for future research directions and E&D of shale gas are formulated.

近年来随着勘探和认识程度的加深,鄂尔多斯盆地不再被认为是“铁板”一块,盆地内多期多套断裂系统对油气成藏的控制作用越来越受重视。选取盆地南部旬邑—宜君(旬宜)地区,基于最新三维地震资料与钻井资料,应用走滑断裂理论模型,开展了断裂几何学与运动学分析,预测了断裂形成机制,并探讨了其对深层碳酸盐岩成储、成藏的控制作用。旬宜地区发育3套断裂系统,且存在深、浅层脱耦现象,下古生界走滑断裂在剖面上呈高陡直立、倾向摆动、“花”状构造等典型特征,平面上表现为“北西部挤压剪切、中部拉张剪切、主干断裂分段变形”。下古生界走滑断裂经历了两期构造活动,其中晚奥陶世至志留纪活动强度较大,为断层主要发育期,中—晚二叠世活动强度较弱,断层呈继承性走滑,形成北东、北西走向两组左行走滑断裂。鄂尔多斯盆地南部可能存在北东和北西向的基底薄弱带,加里东期Ⅱ幕洋盆俯冲闭合向盆内传递应力,斜向挤压导致旬宜地区基底断裂活化,是下古生界走滑断裂系统形成的主要动力机制。下古生界走滑断裂可有效改善深层碳酸盐岩储层物性,形成岩溶型或构造裂缝型优质储层,沿走滑断裂带形成“上生下储—旁生侧储”型成藏组合,是旬宜地区深层油气勘探值得关注的重点领域。

为了评价四川盆地东部震旦系—下寒武统天然气勘探前景,在区域沉积--构造背景分析基础上,利用实测烃源岩总有机碳含量(TOC)、测井和二维地震数据,预测了下寒武统有效烃源岩;综合分析中三叠世末震旦系顶面古构造和下寒武统生烃中心分布,预测了有利油气聚集区。研究结果表明:晚震旦世至早寒武世强烈的沉积--构造分异导致在中上扬子地区形成台内断陷/裂陷槽、台内凹陷和台内凸起;四川盆地东部主要位于台内凸起,有效烃源岩厚度为50~150 m;习水—南川—石柱一带厚度小于30 m,有效烃源岩发育较差;平面上围绕四川盆地东部发育4个由裂陷槽和台内凹陷控制的烃源岩厚度中心及其对应的生烃中心,能够为震旦系—下寒武统提供充足的油气;四川盆地东部天然气勘探前景较好,川中古隆起及其围斜区是有利油气聚集区。
