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,但油层厚度大,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 characteristic of heavy oil layer, serious in-layer heterogeneity, poor development effect in Pucheng oilfield, 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 to nineteen subzones. After subdivision some internal contradiction is transformed to interlayer contradiction. It supplies some warrant for development the reservoir.
