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圈闭进行了评价。
The Shiwu fault depression in the south of Songliao Basin was a half-graben fault developed since the Late Jurassic. It mainly experienced the deposition of the Huoshiling Formation-Yingcheng Formation faulting; the Yingcheng Formation uplifted and eroded at the end of deposition; the Denglouku Formation Depositional sedimentation; Dengloukuang Formation uplifts, slippage and fault block in the sedimentary period; Quantou Formation - Nenjiang Formation Depression sedimentation; Formed a multi-period structure superimposed, multi-phase accumulation characteristics. On the basis of comprehensively analyzing the tectonic evolution of the Shiwu depression and the burial history of source rocks, the authors evaluate the favorable oil and gas zones and favorable traps.
