摘要： 根据储集层与盖层特征及两者的关系,对塔北地区连续式及断续式两大储盖组合进行评价,指出以吉迪克组为盖层, 以苏维依组及上白垩统—下第三系为储集层的组合, 以及以卡普沙良群中上段为盖层, 该群下段为储集层的组合为全区最好的储盖组合。同时探讨了储盖组合与油气运移、聚集的关系, 认为海西运动期及喜马拉雅运动期是两大油气成藏期。

Abstract: According to the characteristics of reservoir and caprock and their relations, evaluation of continuous and discontinuous reservoir-caprock assemblage in Tabei area and suggestion of the most favourable assemblages in study area to be the combination of Jidike formation as caprock and Suweiy iformation and Upper Cretaceous-Paleogene as reservoi r, as well as the combination of mid-upper member in Kapushaliang group as caprock and lower member as reservoir were made.Moreover, this paper discussed the relations between reservoi r-caprock assemblage and hydrocarbon migration and accumulation, and pointed out that Hercynian and Himalayan movement are two reservoir-forming periods.
