松辽盆地东南隆起区十屋断陷油气聚集规律

十屋断陷位于松辽盆地东南隆直区南部，区内断坳叠置，共经历了五次构造运行，其油气成藏规律有别于松辽盆地中央坳陷区，油气源岩 河子组，营城组及登娄库组，在部分断层不能成为油气垂向油气通道的条件下，油气在烃源层内以横向运移为主，形成原生油气藏，经后期强烈改造，部分原生油气藏现到破坏，形成次生油气藏，综合研究认为，勘探靶区的选择应以近源的含油气圈闭为主。

Oil- gas accumulation rules of Shiwu fault depression at southeast uplift area of Songliao basin

Shiwu fault depression lies in the south of southeast uplift area of Songliao basin. The superimposed fault depressions in this area went through five tectonic movements in all. Its oil?gas accumulation rules is different from that of central depression area of Songliao basin. Its oil?gas source rocks are Shahezi formation, Yingcheng formation and Denglouku formation. Lateral oil?gas migration in hydrocarbon source rock beds is dominant under the condition that partial faults can't be the vertical oil?gas passage, then primary oil?gas pool is formed and secondary oil?gas pool is formed after part of primary one was destroyed through strong reformation in later period. It is considered that the proximal hydrocarbon?bearing traps should be selected as the main exploration target area through synthetic study.
