摘要
利用岩心、薄片、粒度分析以及测井等资料，通过详细研究泥岩的颜色、岩石的结构、沉积构造、沉积韵律以及垂向沉积序列等特征，认为头台地区扶余油层主要发育有湖泊相和浅水湖泊三角洲相。湖泊相中又可区分出滨湖亚相和浅湖亚相；浅水湖泊三角洲相中又可区分出水上平原亚相和水下平原亚相。不同沉积相、亚相及微相都有独特的测井响应。探讨了本区扶余油层沉积演化规律，按砂层组建立了沉积模式。浅水湖泊三角洲水上平原亚相和水下平原亚相中分流河道砂体，空间规模大，且含油性能好，是扶余油层有效储层砂体类型。
Using the data of the cores, thin sections, granulometric analysis and well loggings, studying in details the features about the colors of the mudstone, the texture of the rock, sedimentary structures, sedimentary rhythm and the vertical sedimentary sequences, we conclude that the main facies of Fuyu formation are lake facies and shallow water lake delta facies in Toutai area. The shore lake subfacies and the shallow lake subfacies are subclassfied into the lake facies, and the upper and lower water plain subfacies are subclassified into the shallow water lake delta. Different kind facies, subfacies and microfacies respond to characteristic log curve. We deal mainly with the evolutionary regularity about the sediments in the area, and build the sedimentary models. The upper and lower water distributary channel sandstone bodies with high oil bearing performance, which are largely scaled in the space, are effective reservior types in Fuyu formation.
