The Study On Sedimentary Microfacies Of Fuyu Layer In Tai 1 Block, Toutai Oilfield

Many researches such as structure, dividing and correlation of the Sedimentary Unit, sedimentary microfacies, Sandbody Surface Shape, reservoir evaluation have been done in Tai 1 block in this paper:Dividing and correlation of the Sedimentary unit:a principle was followed, that was selecting key wells→making up main framework→other framework. The first step was to divide the sedimentary unit using key wells, the second was to make up main frameworks including these key wells, and the third was to make up oher frameworks. As a result,69 horizontal frameworks and 57 vertical frameworks were made up.Sedimentary microfacies study:the conclusion that delta facies were developed was summarized in the block after the study of core, Lithologica feature and electrical properties. The delta facies in the block were divided in to Delta distributary plain facies, delta front facies, and other ten microfacies such as distributary channel. Sedimentary microfacies pictures were drew with a detailed description to the sandbody feature in every sedimentary unit.
