摘　　要：针对濮城油田南区沙二上2+3油藏构造相对简单、完整,油层厚度大,层内非均质严重,开发效果差的特点,以高分辨率层序地层学为基础,通过对钻井、测井基准面旋回的识别划分流动单元,进而通过基准面旋回对比完成流动单元的对比。最终将储层细化为19个小层,细化后,使得无法解决的部分层内矛盾转化为层间矛盾,为开发调整提供了一定的依据。Aimed at the characteristics of Sa 2+3 members in Pucheng oilfield, i.e, simple and whole reservoir structure, thick pay zone, heavy inner formation heterogeneity, poor development effect, flow unit is divided by identification of drilling and logging base-level cycle based on High-Resolution Sequence Stratigraphy, so as to compare flow unit by correlation of base-level cycle. Reservoir is subdivided into nineteen sub-zones. After subdivision some internal contradiction is transformed to interlayer contradiction, which will supply some warrant to development adjustment.
