川西拗陷中段海相油气输导系统特征
Characteristics of marine petroleum conduit systems in the middle part of western Sichuan depression, China
摘要
Abstract
The effect of marine conduit systems on petroleum migration and accumulation is studied by application of logging,high precision 3D seismic data and surface outcrops in the middle part of western Sichuan depression.The research shows that the marine unconformity surface conduit systems in the middle part of western Sichuan depression mainly exist at the top of the Upper Sinian Dengying Formation,the bottom of Permian,the top of the Middle Permian and in some regions,the top of the Middle Triassic Leikoupo Formation.It reveals that the unconformity surface conduit systems are responsible for the lateral migration of petroleum.Fault conduit systems are developed in Permian strata,Triassic Leikoupo Formation and the Upper Sinian Dengying Formation of Sinian and the fault conduit systems mainly control the longitudinal migration of petroleum.There is a close relationship between the formation of marine petroleum accumulations and fault conduit systems.The petroleum from the ancient petroleum reservoirs formed in the deep layers are migrated to the appropriate shallow reservoirs through the fault conduit systems,forming secondary petroleum reservoirs,such as gas reservoirs in Leikoupo Formation at Pengzhou area.关键词
