摘　　要：通过对车镇凹陷地质特征和油气成藏条件的分析,发现其发育5个含油气系统,5个含油气系统在形成过程中共享油气运移通道和盖层等成藏条件,构成一藏多源、一源多藏的复合含油气系统。复合含油气系统油源充足,成藏条件匹配良好,油气资源丰富,东营组和馆陶——明化镇沉积时期是复合含油气系统油气运聚、成藏的关键时刻。斜坡带和盆地边缘凸起油气资源最丰富,是油气勘探的重点。Through comprehensive analysis of geological character and oil-gas accumulation conditions in Chezhen sag, it is found that there are five petroleum systems, which share the common migration paths and the same cap rocks, forming a composite petroleum system of single-pool-ploy-source and singlesource-multi-pool. An analysis of characteristics and evolution of source rocks and petroleum systems indicates that, with fairly good matching of pool-forming conditions, the composite petroleum system is petroliferous. The critical periods for migration and accumulation are during the deposition of Ed, at the end of Ng and Nm. Oil-gas is abundant in slope and arch of the basin edge, which are important areas for oil-gas exploration.
