摘要： 车古20潜山总体为一背斜状构造。轴向北北东,两侧受堤南断层和二台阶断层共同控制,次级断裂的发育将潜山切割成许多断块。潜山主要由太古界、古生界地层组成,下古生界寒武系、奥陶系灰岩发育。加之构造作用风化的改造,形成了良好储集层。车古20潜山形成于古近纪孔店组早期,相邻的车西洼陷沙三段烃源岩发育,油源充足,生油洼陷-断层-潜山构成了有利的生-运-圈油气成藏体系,故该潜山是较有利的油气勘探区。

Abstract: Clegu-20 buried hill is am anticline-like structure with NNE axial trend, Chengnan and Eraijie faults at both sides and developed secondary fauls which cut it into several blocks. It consists of Archaeozoic and Paleozoic strata in which Cambrian and Ordovician arc dominal-ed by limestone. The tectonism and weathering make it become a good reservoir. Chegu-20 buried hill was formed in early Kongdian fornation of Pauleogene. Sha 3 meuber of Choxi sag adjacent to Chegu-20 buried hill is a favorable source-migration-trap system for hydtocarbon accumula-tion with developed source rocks, abundant vil sources and source sag-faulting-buried hill configuration. It is suggested that Chegu-20 buricd hill might be an advantageous area for oil-gas prospecting.

Key words: Shengli oilfield, buried hill, reservoir, fauling, origin
