鄂尔多斯盆地合水地区庄211井区延长组长8沉积微相特征研究

摘要

结果表明，长8油层组为三角洲前缘亚相，发育水下分流河道、水下分流河道侧翼、河口坝、分流间湾、席状砂等5种微相类型。%This article presents the study on Chang-8 sedimentary microfacies in Zhuang-211 block,Heshui Area,Ordos Basin. The results show that the Chang-8 reservoir is front-delta subfacies,which involves subaqueous distributary channel, subaqueous channel flank,mouth bar,interdistributary bay and sand sheets.
