Mu Xiaoshui (Scienctific Research Institute of Petroleum Exploration and Development,Zhongyuan Oilfield Company,SINOPEC,Henan 457001,P.R.China),Yuan Xiaorong and Jia Yifang et al.  
Combing with the geological characteristics of Dongpu depression,this paper discusses the geological conditions concerning the formation of the oil pools formed in the fractures of the shales.The oil source is well developed in Dongpu depression,and so are fractures in shales,which have better conditions to form the oil pools in the fractures in shales,the new type of reservoir that has the prospect for the future exploration.This paper also studies the distribution of this sort of oil pool in this depression,and points out that the area with high abnormal pressure;salt distribution area and the structure transforming zones ard favorable.Vertically,this sort of oil pools can be easily found in the members from Es2 to Es4,because there are some stable shale or clay marker beds in them.
