【摘要】 通过对物源方向、沉积微相、砂体展布的分析 ,采用渗透率变异系数、渗透率突进系数、渗透率级差、渗透率均质系数等定量参数 ,对尕斯库勒油田砂西区块E13 油藏I 6小层的非均质性进行了系统的研究。通过研究认为 :分流河道主体部位的储层 ,无论在纵向上还是在横向上 ,其均质性较强 ;分流河道的边部、前端以及各分流河道交汇处则非均质性较强 ;并且 ,对于具有二元结构的正旋回储层来讲 ,纵向上存在一定的非均质性更多还原

【Abstract】 By the analysis of sources direction, sedimentary micro-facies, sandstone distribution, adopting qualitative parameters, i.e., permeability mutation coefficient, permeability dash coefficient, permeability graded difference, permeability equal coefficient etc., the heterogeneity of from one to six sand beds of the E¹₃ in the west tract of gasikule oilfield is systematically studied in this paper. The results of study show that the vertical and horizontal heterogeneity in the main belt of interdistributary river area is stronger than the heterogeneity in the marginal and the front and the intersection areas of interdistributary river area. Moreover, there is the vertical heterogeneity in the positive rhythmic reservoir which has binary structure.更多还原
