摘要

以黄骅坳陷王官屯油田王27断块为例,提出断块油气田非均质储层流动单元评价方法。通过单砂层对比揭示砂体平面展布特征,再结合断层封闭性分析及砂体构型分析,划分单个流动单元(连通体);对储层产能敏感的储层参数进行聚类分析,将单井流动单元分为E、G、M和P共4类,并建立流动单元展布模型。研究表明,断层、沉积相及砂体内部结构控制着流动单元的边界,流动单元优劣受控于沉积、构造及储层流体性质。这一研究对于优化油田开发调整方案将具有重要的借鉴意义。

Abstract

As a case of the Faulted Block W27 of WGT oilfield in the Huanghua depression,the flow units of heterogeneous reservoir in faulted blocks were pointed out.The sandbody distribution was made by the single sandbody correlation,and the single flow unit was identified after determination of fault sealing and sandbody architecture.The assembling analysis on the reservoir properties which were sensitive to the well performance was carried out,and the flow units were classified into four grades(grade E,G,M and P) and the model of the flow unit distribution was setup.The result indicated that the boundaries of the flow units were controlled by faults,sedimentary facies,and inner architecture of sandbody,and the quality of the flow units was controlled by sedimentology,structure,as well as property of reservoir fluids.It is important to optimize the plan of oilfield development and adjustment.
