松辽盆地南部的十屋断陷是晚侏罗世以来发育而成的箕状断陷，主要经历了火石岭组-营城组断陷沉积；营城组沉积末期抬升剥蚀；登娄库组断陷沉积；登娄库组沉积末期抬升、走滑、断块作用；泉头组-嫩江组坳陷沉积；嫩末、明末挤压抬升、走滑作用。形成了多期构造叠加、多期成藏的特点。笔者在综合分析十屋断陷构造格架演化和烃源岩埋藏史的基础上，对油气有利区带和有利图闭进行了评价。

The Shiwu Fault Depression in the south part of Songliao Basin is a halfgraben-like depression having been formed through evolving since Late Jurassic, being mainly undergone the following processes: Huoahiling Formation-YingehangFormation fault depression sedimentation; rising and being eroded at the sedimentary end of Yingchang Formation; Denglouku Formation fault depression sedimentation; the rising, strike-slipping, and fault-blocking at the sedimentary end of Denglouku Formation; Quantou Formation-Nenjiang Formation depression sedimentation;and the compressional rising and strike-slipping at the sedimentary ends of Nenjiang Formation and Mingshui Formation. Therefore the properties of multiphase structural superposition and multistage reservoir formation are displayed. On the basis of comprehensively analyzing the structural framework evolution and source-rock burial history in Shiwu Fault Depression, the favourable oil and gas zones and traps are evaluated in the paper.
