摘　　要：隐蔽性储集层分离是个很难识别的问题,由于分辨率的问题,地震和地质资料在此类识别上存在缺陷。从Z408砂体和Z411砂体的物性特征和孔隙结构特征入手,证实两个砂体的存在,然后根据物性差异分析对物源方向进行了分析,论证了依据孔隙度模式的不同指示隐蔽性储集层分离的可行性。Subtle reservoir division is a hard problem,for the iden- tification on seismic and geological data is defective in resolu- tion.Through the study on physical property character and pore structure character of Z408 and Z411 sand bodies,the existence of' the two different sand bodies is proved.Then the provenance direction is analyzed in terms of discrepancy of physical properties.It is demonstrated that it is feasible to acquire the subtle reservoir division from the porosity mode.
