摘要: 从烃源岩的热演化史,构造的形成演化史,储集岩的成岩作用史分析论证了柯克亚背斜下第三系始新统卡拉塔尔组及上第三系中新统油气藏的形成及成藏模式。卡拉塔尔组凝析气藏的形成具下断上褶垂向运移和不整合面倒向运移双重运聚模式。中新统带油环的凝析气藏的形成具侧断背科型运聚模式。断裂及不整合面是油气运移的主要通道。

Abstract: In terms of diermal history of source nock, tectonic history, and diagenetic history of reservoir rock, this paper analysed and verified the formation and its model of Karatar formation reservoir of Eocene (Paleogene) and Miocene (Neogene) reservoir. Karatar formation condensate gas reservoir formed in a dual migration-accumulation mode with vertical migration from the lower fault to the upper fold and lateral migration along unconformity surface, while Miocene condensate gas reservoir with oil-ring formed in migration-accumulation mode, with fault and unconformity surface as the main passage.
