摘　　要：通过对东辛油田沙三段5砂层组4小层的构造特征进行分析,确定其南部的小断层为一个逆断层,北部升高,南部降低,为油气聚集构成了圈闭条件.同时对于该地区砂体厚度以及地层厚度进行分析,确定其物源来自南部、西部及北东部.在该地层中,没有北部物源.最后通过该地区孔隙度、渗透率以及砂体有效厚度的分析,确定最有利勘探区域依次为南部区域、中偏西部区域,其次是北东部区域;中偏东区域勘探意义很小.By analyzing the structural characteristics of No.4 sub-layer,the 5th sand set of the 3rd Member,Shahejie Formation(Es3)in Dongxin Oilfield,a small fault in the southern part is determined as a reverse fault,making uplift in the north and depression in the south,which provides the trap condition for oil-gas accumulation.The study on the sand body and formation thickness indicates that the provenances are from the south,west and northeast rather than north.Finally,with analysis on the porosity,permeability and effective thickness of sand body,it is found that the most favorable exploration areas are the south and mid-west regions,followed by northeast region,while the mid-east region is of little significance for exploration.
