Abstract: Based on the new outcomes obtained from oil exploration and new understandings and development of petroleum geology theories gotten in the past few years, analyzing effective source rocks in Jiyang Depression (including beach area), the genetic method, statistical method, and analogical method are applied to comprehensively evaluate the oil resources in the depression by taking oil accumulating units as the evaluation unit. A new approach is established to evaluate exploration potential on the basis of resources and degree of reliability, which has been used to select 15 favorable oil and gas exploration units, such as the north slope in Dongying sag, the central anticline belt of Dongying sag, the central anticline belt of Huimin sag, the north slope of Chezhen sag, Gudao and Chengdao regions of Bonan Oilfield. The results have been proved by exploration practic
