松辽盆地南部十屋断陷构造特征研究
|
摘要
十屋断陷位于松辽盆地东南隆起区南端,是一个断坳叠置型复合盆地,下部为西断东超单断箕状盆地,地层由西向东部斜坡区逐层超覆.本文通过对700多平方公里三维地震资料的解释成果研究认为,十屋断陷的构造特征呈“三隆两凹”特征,三隆分别为:中央构造带、秦家屯-艾家构造带和皮家构造带;而其间由两个凹带(十屋深凹区、小宽深凹区)所分割.十屋断陷深层油气主要聚集在这三个构造带上.三个构造带的产生原因与基底断层密切相关.营城组末期和登娄库组末期的构造运动对油气的早期生成和聚集都起到至关重要的作用,在这两期形成的局部构造都是油气聚集的重要场所.
The Shiwu Fault Depression is in the south of Southeast Uplifted Area of Songliao Basin.It is a complex basin with fault sag folding.The lower is half graben-like basin with single fault,which faults towards the west and overlaps towards the east.The study on the results of 3D seismic interpretation of 700 km~2 data,it is thought that the structural feature of Shiwu Fault Depression has the feature of "three-uplifts and two-depressions".The three-uplifts are individually Center Structural Belt,Qinjiatun-Aijia Structural Belt and Pijia Structural Belt,which is divided by two depressions.Deep zone oil and gas of Shiwu Fault Depression are mainly accumulated these three structural belts.The ending tectonic movement of Yingcheng Formation deposition and Denglouku Formation deposition plays important role in the early generation and accumulation of oil and gas.During these two deposition,the local tectonics are all the important places of accumulation of oil and gas.
