摘　　要：结合子洲油田石宅河区录、测井资料以及地层岩性、粒度、沉积构造等相标志,分析了该区延长组长6油层沉积微相特征。结果表明,长6油层组属三角洲平原亚相,其中包括分流河道、决口扇、分流河道间微相。同时对长6油层组各小层沉积微相的时空展布特点进行分析,认为油气聚集受沉积微相控制,分流河道微相为长6油层组良好的储集层,是研究区油气开发的方向。According to facies marks such as logging data, layer lithology, grain size and sedimentary structure of Shizhaihe area in Zizhou oilfield, characteristics of sedimentary microfacies in chang 6 reservoir were analyzed. The results show that, Chang 6 reservoir belongs to delta plain subthcies, including distributary channel, crevasse splay, interdistributary microfacies. At last,evolution and distribution of the microfacies in every number were studied. It＇s pointed out that accumulation of oil and gas is controlled by the microfacies. The distributary channel microfhcies of Chang 6 is a good reservior, and is also the direction of developing Zizhou oilfield.
