摘　　要：通过对华池油田华152井区10口井岩心观察及200多口井的单井沉积相、剖面相、平面相的分析研究,认为该区长3油组为一套曲流河三角洲沉积,可见到曲流河三角洲前缘和前三角洲两个亚相.对研究区沉积微相进行了深入细致的研究.讨论了沉积微相与含油性的关系.结果表明,水下分流河道的储集性能最好,河口砂坝次之,远砂坝较差.According to the core observation of 10 wells and the analyses of single well sedimentary facies, profile facies and plane facies of over 200 wells in the study area, it is held that Chang 3 oil-bearing strata is a set of meandering stream delta deposition system. Two subfacies of meandering stream delta front and prodelta are found. The sedimentary microfacies in this area are studied in detail. The relationship between the sedimentary microfacies and the oil-bearing characters is discussed, and it is shown that the oil reserving ability of submerged distributary channel is the best, that of debouch bar is second, and that of distal bar is the worst.
