摘　　要：本文从烃源岩生、排烃史和油气注入期次两个方面结合分析了东濮凹陷油气成藏过程,指出东濮凹陷东营组沉积末期的抬升剥蚀前后是两个截然不同的地质演化阶段,之前的持续沉降阶段是烃源岩生、排烃的高峰时期;而抬升剥蚀期的构造运动为油气大规模二次运移提供了强大动力,是油气成藏的关键时期。Based on the generation and expulsion history study of the main source rocks,combined with the study of hydrocarbon injection time of the oil sand,the reservoir forming process of Dongpu depression are analised.according to the result from the above study,those are the different evolution stages that prerising and rising stages with bed-erosion of the basin at the deposition end of Dongying formation.the hydrocarbon generation and expulsion reaches max-peak in the pre-rising stage.however,the structural movement brings enormous kinetic power for the hydrocarbon migration in the rising stage,for this reason,it＇s the key time for reservoir forming.
