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。
Based on the thermal evolution history of hydrocarbon source rocks, the tectonic evolution history and the diagenesis history of reservoir rocks, it is demonstrated that the Paleo-Proterozoic Karataal Formation and the Upper Miocene Miocene oil-gas in the Kekeya anticline Formation and accumulation of Tibetan model. The formation of the condensate gas reservoirs in the Karataal Formation has the following modes: the vertical migration of the upper fold and the reverse migration of the unconformity. The formation of condensate gas reservoirs with oil rings in the Miocene and the Eocene can be characterized by a faulting and dorsal-type transport and accumulation model. Faults and unconformities are the main channels for hydrocarbon migration.
