摘要
通过岩心观察和测井资料分析,结合研究区的构造背景和沉积环境,对鄂尔多斯盆地胜利山油田长63砂层沉积微相进行了研究。结果表明,胜利山油田长63砂层为一套湖泊三角洲为主的砂泥岩互层沉积,属三角洲前缘亚相,主要微相类型为水下分流河道、分流间湾微相类型。该研究区长63砂层的砂体以水下分流河道沉积为主,从西到东共发育4支由多期河道叠加形成的水下分流河道砂体,是良好的油气储集场所。
According to the core observation and logging data collection,combined with a large number of comprehensive analysis of the structural setting and sedimentary environment of Shenglishan Oilfield,a deep understanding of the types and characteristics of the sedimentary microfacies of the Chang 63.The results of the study show that the Chang 63of study area developes a set of lake delta sand mudstone interbedding deposit,belongs to delta front subfacies.The main microfacies types have subaqueous distributary channel and subaqueous interdistributary bay.The study on sand-body of the Chang 63mainly focuses on subaqueous distributary channel deposition,from the east to west of the sand body,four multi-period superimposed subaqueous distributary channel sand-bodies developed,which is favorable for oil and gas accumulation.
