塔里木盆地柯克亚凝析油气田主要发育中新统上、下油组及始新统深部油组，由7个凝析油气藏组成。柯克亚背斜在安居安期即具雏形，主要形成千上新世末-早更新世。深部油组以侏罗系为油源，中新统上、下油组以石炭系—下二叠统和侏罗系为混合油气源。柯克亚油气田具三阶段成藏模式，即“古油藏形成，背斜雏形期油气充注，晚期驱替成藏”。上、下油组为决生凝析气藏，深部油组为原生凝析气藏。根据对柯克亚周围地区钻探失利原因的分析，提出应对山前第二排背斜带落实深、浅层构造，加强成藏机理研究，选择相对简单的背斜先行钻探，可望取得油气勘探的突破性进展。
The main Keleya condensate oil and gas field in the Tarim Basin is mainly composed of the Miocene upper and lower oil groups and the Eocene deep oil group, which consists of 7 condensate reservoirs. The Kekeya anticline was a prototype during the security period and mainly formed at the end of the millennium to the end of the Pliocene - Early Pleistocene. The deep oil group uses Jurassic as oil source, and the Miocene upper and lower oil groups are composed of Carboniferous-Lower Permian and Jurassic mixed hydrocarbon source. The Kekeya oil and gas field has a three-stage model of accumulation, that is, “the formation of paleo-oil reservoirs, the filling of hydrocarbons in the anticline and the replacement in late-stage reservoirs.” The upper and lower oil formations are condensate gas reservoirs, while the deep oil formations are the primary condensate gas reservoirs. Based on the analysis of the cause of drilling failure in the area around Ke’koya, it is proposed to deal with the deep and shallow structures of the second row of anticlines in the front of the Piedmont, to study the mechanism of hydrocarbon accumulation and to select the relatively simple anticline incline drilling. The breakthrough progress.
