摘要
克拉苏构造带是库车坳陷北侧的一个重要构造单元,已发现大量天然气。通过二维、三维地震解释资料,并以白垩系地层为目的层,建立三维构造模型。基于变换构造理论,对其形成机制进行了研究,确定克拉苏构造带存在构造变换。构造变换的形成与不同方向的区域构造应力有关,构造变换的形成为油气聚集提供了良好的储集空间以及封盖条件。
Kelasu belt is a major tectonic unit north of the Kuqa,where a large number of natural gas have been found.Three dimension structure model was built about Cretaceous target zone,based on two-three dimension seismic data.At the basis of transfer structure theory,mechanism of structure formation is studied.Therefore,it is determined that there existes structural transformation at Kelasu belt,and the formation of structural transformation is related to the different directions on the regional tectonic stress.Moreover,the structure provides good storage space and cover conditions for the oil-gas accumulation.
