在结合地震、岩心、测井、录井、分析化验等资料的基础上,对板桥油田沙河街组储层进行沉积微相研究,属于重力流水道沉积、滩坝沉积。可划分为主水道、分支水道、水道漫溢、湖相泥、砂坝中心、砂坝侧翼、滩砂及浅湖泥等八种微相,明确了沉积微相的平面展布特征,为后续的开发调整工作奠定基础。
Based on the data of seismic, core, well logging, logging and analysis, the sedimentary microfacies of Shahejie Formation reservoir in Banqiao Oilfield are studied, which belongs to gravity flow channel sedimentation and beach dam deposition. It can be divided into eight types of microfacies: main channel, branch channel, overflow of channel, mud of lake facies, center of sand dam, side of sand dam, beach sand and shallow lake mud, etc. The characteristics of plane distribution of sedimentary microfacies are clarified, Development and adjustment laid the foundation.
