摘要

摘要: 辽东湾坳陷走滑活动明显,共发育西部走滑、辽西伸展—走滑、辽中1号、辽中2号和辽东1号5条大型走滑断裂带,这些断裂带差异特征明显,表现出"东强西弱"的特征。根据这一特征把这些断裂分为2个带,即东部"单一强走滑带"和西部"双重弱走滑带",其中东部断裂走滑活动强,走滑特征明显;西部断裂走滑活动弱,只有局部具有走滑特征。走滑断层的差异性,形成了不同的走滑构造,控制了不同类型圈闭的形成以及油气的运移和聚集,进而直接决定了大中型油气田的形成和分布。

Abstract: Strike-slip fault activities are common in the Liaodong Bay Depression.There are five major strike-slip fault zones, including the western strike-slip fault, Liaoxi extensional strike-slip fault, Liaozhong1 fault, Liaozhong2 fault and Liaodong1 fault.The characteristics of these faults are obviously different, generally strong in the east and weak in the west.As a result, the faults are divided into two fault zones: a "single and strong strike-slip fault zone" in the east and a "duplex and weak strike-slip fault zone" in the west.The eastern strike-slip activities are strong and the strike-slip features are obvious.The western strike-slip activities are weak and only a part of them shows strike-slip characteristics.The differences among strike-slip faults result in the formation of different strike-slip structures.These also control the formation of different types of traps as well as the migration and preservation of oil and gas, which ultimately determines the formation and distribution of large and medium-scaled oil and gas fields.
