摘　　要：通过对乌夏地区二叠系油气成藏条件分析认为:二叠系油源充足,圈闭众多,储层虽岩性较复杂,但分布有规律,生储盖组合有利,断裂活动期与烃源岩生烃期相匹配,且在二叠系油气成藏后,构造活动变弱,对二叠系油气藏的破坏作用小.有利储层为二叠系油气成藏的主控因素,在二叠系勘探部署中,重点应在碎屑岩储层中找次生孔隙发育带,在非碎屑岩储层中找裂缝发育带.Through analysis on the forming conditions of Permian＇s hydrocarbon reservoirs in Wu-Xia Area, Permian is considered to be full of sufficient oil sources and traps, although its lithology is various and complicate, reservoirs distribute regularly; So there is a beneficial source-reservoir-cap in the region of interest. Fracturing activity period matches with the hydrocarbon generation period, moreover, the structure activity becomes weaker after hydrocarbon accumulation, which brings little damage to the Permian＇s reservoir. The main factor of hydrocarbon accumulation is favorable reservoir, at the next stage of Permian＇s exploration, the key work is to search secondary porosity belt in clastic rock reservoir, and fracture belt in particular lithology reservoir.
