摘要

针对王集油田王17断块中低渗断块油藏非均质严重

注入水沿高渗透条带突进

采出程度低

水驱提高采收率能力有限的问题

开展了化学驱提高采收率技术研究

评价筛选了聚合物、黏弹颗粒驱油剂（PPG）

应用物模技术对复配形成的非均相驱油体系段塞结构、驱油效率及分流率进行评价

应用数模技术

优化了段塞量及结构

预测王17块采用多级非均相调驱段塞聚合物驱可提高采收率8.25个百分点

现场应用已初见成效

该技术成果已在下二门油田B238块聚合物驱项目借鉴推广应用。

Abstract

In order to solve the problems of serious heterogeneity

breakthrough of injected water along high permeability zone

low recovery percent of reserves and limited EOR capability of water flooding in the middle and low permeability fault-block reservoir of Wang-17 Block in Wangji Oilfield

the EOR technology of chemical flooding has been studied

and polymer and preformed particle gel（PPG） have been evaluated and screened. The slug structure

oil displacement efficiency and diversion rate of heterogeneous oil displacement system formed by compounding have been evaluated by physical simulation technology. And the slug volume and structure have been optimized by numerical simulation technology. It is confirmed that multi-stage heterogeneous profile control and slug polymer flooding can improve the recovery rate in Wang-17 Block by 8.25 percentage points. The field application has achieved initial results. This technology has been used for reference and popularized in the polymer flooding project of B238 Block in Xiaermen Oilfield.
