摘要: 利用动态联系与整体相结合的思路,分析了柴达木盆地西部地区沉积演化和古构造特征,确定了该地区主要成藏期。根据主要成藏期沉积与古构造配位特征,划分了各地质历史时期的含油气系统。以时间为主线,以要素的空间有机组合研究为基础,再现了盆地各个地质历史时期含油气系统的演化特征,并对研究区各区带的含油气性进行了评价,指出了有利的油气聚集区。

Abstract: The sedimentary evolution and paleostructure in the western Qaidam Basin were discussed by combining dynamic and whole states.The main hydrocarbon filling periods in this area were determined.The characteristics of coordination between sedimentation and paleostructure in the main accumulation timings in the western Qaidam Basin were applied to divide petroleum systems in the different geologic periods and the present time.The dynamic evolution characteristics of petroleum systems in the different geologic periods of Qaidam Basin were presented analyzing the main contents in the critical moments,regarding the geologic time as the main thread and taking the organic combination of elements in space as the base.The oil plays in every area were evaluated,and the favorable petroleum gathering area was confirmed.

Key words: Qaidam Basin, petroleum system, dynamic evolution, sedimentation feature, paleostructure, oil and gas evaluation
