十屋断陷小宽断裂带的走滑特征研究及其勘探前景分析
|
摘要
松辽盆地十屋断陷四五家子构造带走滑断层非常发育,小宽走滑断层贯穿研究区南北,沿断裂带已经发现了四五家子、后五家子、八屋等油气田,说明该走滑断裂带是一个油气相对富集的区带。但断层的持续走滑,使得走滑断裂带成为构造破碎的复杂断裂带,精确落实构造的难度相当大。基于高精度三维地震资料解释结果,分析了小宽断层的剖面特征、平面特征和空间特征,总结了走滑断层对烃源岩、储层和圈闭的形成以及油气运移的作用,认为走滑断裂带是寻找构造油气藏的有利场所,指出位于小宽断裂带北部的太平庄构造是下一步构造油气藏勘探的目标。
Strike-slip faults well develop at Siwujiazi structural belt of Shiwu fault depression in Songliao Basin.The Xiaokuan strike-slip faults run through the work area with the direction north-south.Along the faulted zone,we have discovered a series of oil and gas fields such as Siwujiazi,Houwujiazi and Bawu,which shows that the strike-slip faulted zone is an oil-gas relatively concentrated zone.However,the continuous strike-slip of faults changed the faulted zone into complex faulted zone with broken structures;it is difficult for accurately ascertaining the structures.Based on high-precision 3-D seismic data interpretation results,the section features, plane features and spatial features of Xiaokuan faulted zone were analyzed,the impact of strike-slip faults on the forming of hydrocarbon source rock,reservoir and traps,as well as hydrocarbon migration was summarized.The results show that strike-slip zone is potential for finding structural reservoir,and it is pointed out that the Taipingzhuang structure in the north of Xiaokuan faulted zone is the target for further structural reservoir exploration.
