摘要:

通过对钻井岩心资料系统观察以及地震资料的全面检查,证实新疆三塘湖盆地内存在走滑构造,表现为简单走滑(逆—平移)断层和正花状走滑断层两种基本形式。在中央拗陷带内走滑断层与边界主断层斜交并呈“雁列式”排列,表明走滑构造可能在边界断层发生大规模逆冲兼右行走滑时形成,其形成时期可能为喜山期。同时走滑构造对油气的生成、运移与聚集起着重要的控制作用。

Abstract:

Based on drilling-wells and  seismic data, it was proved that there are strike-slip tectonics in Santanghu basin in the following two basic forms:simplified strike-slip faults and positive flower strike-slip faults. Strike-slip tectonics formed possibly in Himalayan Period when the boundary faults thrusted and right lateral strike slipped concurrently,intersect the boundary faults of the central geotectogene and collocate like the en-echelon faults. They play an important role in the generation, migration and accumulation of hydrocarbons

Key words: Santanghu basin, strike-slip tectonic, trap, Xinjiang
