摘要

利用伊舒地堑方正断陷重点研究区6口井的岩心、录井、测井、重矿物资料和三维地震资料,研究方正断陷在新安村组沉积相类型,识别出3种沉积相,即扇三角洲相、湖泊相和湖底扇相;5种沉积亚相,即扇三角洲平原、扇三角洲前缘、前扇三角洲、滨浅湖和半深湖;7种沉积微相,即水上分流河道、河道间、水下分流河道、河口砂坝、席状砂、砂质滩坝、泥质滩坝.研究区的LSC2地层与LSC1地层相比,湖盆面积扩大,东北部物缘能量减弱,西北部物缘能量增强.
Using the cores from 6 wells,logging data,heavy minerals and 3D seismic data from Yishu graben section of Fangzheng fault depression,we have studied the sedimentary facies characteristics of Xin'an village group's oil display section in Fangzheng fault depression and found three sedimentary facies: Fan deltaic facies,lacustrine facies and lake-bottom fan facies,five sedimentary sub-facies: they are fan deltaic plain subfacies,fan deltaic front subfacies,front fan deltaic subfacies,shore-lacustrine subfacies,and half depth-lacustrine subfacies;nine sedimentary micro-facies: distributary channels,between-distributary channels,underwater distributary channels,river mouth bars,sand sheets,sandy beach bar and mud bar.
