摘要：

针对胜利油区孤东油田七区中新近系馆陶组上段曲流河沉积,按照层次分析思路及模式拟合的方法对地下点坝构型进行表征分析,总结了曲流河各沉积微相的岩电特征,并结合曲流河沉积模式,划分了研究区沉积微相,识别出两个点坝。综合应用开发动态资料及测试资料,认知了点坝内部构型单元的定量模式,即侧积层的倾向、倾角、间距以及单一侧积体水平宽度,以模式为指导,以井数据为约束,对点坝内部构型进行精细解剖,最终建立曲流河点坝构型三维模型,并进一步分析了剩余油分布规律,提出了相应的挖潜措施。

Abstract:

Hierarchy analysis and model fitting techniques are used to describe the point bar configuration of the meandering river deposits in the Neogene Guangtao Formation in the middle unit of Block 7 in the Gudong oilfield.According to the lithologic and electrical properties of sedimentary microfacies in the meandering river deposits and in combination with the modes of deposition,we divide the sedimentary microfacies and identify two point bars in the study area.With production performance and test data,quantitative models of point bar configuration unit are built,which includes the orientation,dip,space and horizontal width of a single lateral-accretion sandbody.Under the guidance of the models and constraints of well data,we analyze in detail the internal configuration of the point pars and build 3D models for point bar configurations of meandering river deposits.Furthermore,we analyze the remaining oil distribution and presents specific measures to tap the production potential.

Key words: point bar, lateral-accretion layer, remaining oil, reservoir configuration, Gudong oilfield, Jiyang Depression
