摘要
通过岩心观察以及测井、录井资料的研究,对濮城油田沙一段各砂组的沉积特征和沉积微相的平面展布特征进行了分析,识别出研究区发育三角洲相和湖泊相2种相类型。其中三角洲相发育有水下分流河道、河口坝、远砂坝、前缘席状砂和前三角洲泥微相;湖泊相发育有浅湖滩砂、浅湖砂坝和浅湖泥微相。在综合考虑宏观沉积背景及微观沉积特征的基础上,根据沉积相的演化规律,建立了研究区的沉积模式,并得出其沉积特征。
According to the research on the core and well logging data of the first member of Shahejie Formation,this paper analyzes the sedimentary characteristics and distribution of the sedimentary microfacies of the area.Delta facies and lake facies are developed in the research area.The delta facies developed subsea river channel,mouth bar,distal bar,frontal sand sheet and predelta mud microfacies;Lake facies developed shallow-lake beach sand,shallow-lake sandbar and shallow-lake mud microfacies.The sedimentary m...
