摘要

根据野外露头、岩芯、测井及相关测试资料,分析了鄂尔多斯盆地安塞油田晚三叠世延长组长6油层组的沉积微相。结果表明,长6油层组属三角洲前缘亚相沉积,水下分流河道、水下分流间湾及前缘席状砂构成其主要微相,缺少河口坝微相。水下分流河道砂为储集层骨架砂体。同时对长6油层组各小层沉积微相的时空展布特点进行了分析,认为油气的聚集受沉积微相的控制,水下分流河道微相为长6油层组良好的储集层,是研究区油气开发的方向。

Abstract

According to the outcrop observing and the  core describing as well as lots of data analyzing, it indicated that front-delta deposition is the main sedimentary system of Chang 6 in Ansai district. The  distributary channel deposits, the inter-distributary deposits and the sands are the main sedimentary microfacies in the studied area while the point bar isn't  development. The distributary channel deposits is the main reservoir sands. The evolution and the distribution of the microfacies in every number have been  studied. The accumulation of oil and gas are controlled by microfacies. The distributary channel deposit of Chang 6 is the good reservoir, and also is the   direction of the developing in Ansai oil field.
