摘要
柴达木盆地主要发育背斜构造 ,根据其成因可将盆地中的背斜构造归纳为生长背斜、断展背斜、纵弯背斜和滑脱背斜等 4种基本类型。受区域构造环境、盆地基底性质、应力作用方式、岩石物理性质和构造演化阶段的控制 ,上述背斜在平面上和垂向上的展布存在着明显的规律性 :生长背斜是主要的含油气构造 ,反冲断层控制下的断展背斜是重要的含油气构造 ;生油范围内的纵弯背斜可形成油气藏 ;
The multitudinous anticlines are chief structures in Qaidam basin. The anticlines are divided into four types of growth anticline, fault propagation anticline, longitudinal bend anticline and detachment anticline according to their genesis. The distribution of these anticlines is regular on horizontal and vertical orientations and is controlled by the geotectonic environment, basement nature, stress state, physical nature of rocks and stage of tectonic evolution. In Qaidam basin, growth anticline is the main oil\|bearing structure, and the fault propagation anticline controlled by back thrust is an important oil\|bearing structure. The longitudinal bend anticline in generative oil area may be oil pool, and it is gas\|bearing structure in the central part of central depression.
