复合河道砂体叠置样式与剩余油主控因素研究
Study on Superimposition Patterns and Main Remaining Oil Control Factors of Channel Sand-bodies
摘要
Abstract
The spatial contact relationship of channel sand-bodies was analyzed according to the reservoir configuration theory and the core,dense well pattern,logging and dynamic development data.The superimposition patterns of the channel sand-bodies in the block 3 of Gangxi Oilfield were analyzed based on the stage of single channel,the development degree of interlayer and the ratio of deposition rate and accommodation space,and the result shows that there are 5 contact relationships of channel sand-bodies in the study area,that is,isolated,bridging,superposed,cut-superposing and compound.The isolated style and the bridging style are subdivided into 2 types according to the stage of sand-bodies.In addition to the isolated sandbody,there is different extent of remaining oil in other 4 types of sand bodies,which is controlled by sedimentary rhythm and interbed,and the interbeds in meandering point bar sand-body and the cutsuperposing type sand-body are main control factors of remaining oil in the channel sand-bodies.关键词
