海拉尔盆地乌尔逊凹陷南部大磨拐河组二段沉积相研究
|
摘要
充分利用岩心、录井和测井资料,综合地震特征,对乌尔逊凹陷南部大磨拐河组二段展开沉积相特征研究,认为大磨拐河组二段沉积时期发育湖泊相和三角洲相,其中湖泊相发育滨浅湖和深湖-半深湖两个亚相,三角洲相发育三角洲平原和三角洲前缘两个亚相。三角洲平原和前缘亚相砂体发育,其中分流河道、水下分流河道和河口坝砂体最为发育,是研究区有利储层发育相带。
Based on coring data,well logging data and seismic data,sedimentary facies study of the second member of damoguaihe formation in the south of Urxun sag is developed,lacustrine facies and delta facies are identified. The lacustrine facies develops shallow lake subfacies and deep lake subfacies,the delta facies develops delta plain and delta front subfacies. Delta plain and delta front subfacies develop sand body,distributary channel,underwater distributary channel and mouth bar are most developed,they are favorable reservoir facies belt in the region of interest.
