四川盆地雷口坡组构造与油气输导系统研究

Study on Structure and Hydrocarbon Transmission System of Leikoupo Formation in Sichuan Basin

摘要: 通过分析四川盆地雷口坡组的沉积和构造特征，分析构造地质与油气成藏中的输导体系，对盆地范围内的不同位置的不同构造差异进行区分，结合构造地质的过程，将油气的生成、运移方式、运移路径结合，划分出了断层及破碎带–优质(内幕)储层外源源–汇输导系统、断层及破碎带–褶皱、断层伴生裂缝层楼式外源源–汇输导系统、褶皱、断层伴生裂缝–优质(内幕)储层层内源源–汇输导系统、雷口坡组风壳–优质(内幕)储层外源源–汇输导系统、断层及破碎带–雷口坡组风壳长距外源源–汇输导系统五种输导体系，通过不同输导体系分析，指出四川盆地雷口坡组勘探潜力巨大。

Abstract: By analyzing the sedimentary and tectonic features of the Leikoupo Formation in the Sichuan Ba-sin, this paper analyzes the structural geology and the transport system in hydrocarbon accumu-lation, distinguishes different structural differences in different locations within the basin, and combines the process of structural geology with the combination of generation, migration mode, and migration path has divided faults and fracture zones-high-quality (insider) reservoir source-sink transmission systems, faults, and fracture zones-folds and faults associated with cracks, and associated fractures in faults-high-quality (Inside) Reservoir Source-Sink Conveyor System, Leikoupo Formation Wind Shell-High-quality (insider) Reservoir External Source-Sink Conveyance System, Fault and Breakage Zone-Leikoupo Formation Wind Shell Long Distance Source. The five transduction systems of the transfusion system, through analysis of different transduction systems, indicate that the exploration potential of the Leikoupo Formation in the Sichuan Basin is huge.
