摘要: 安塞油田自2016年起开展聚合物微球调驱工作,先后经历先导试验、扩大试验和规模推广三个阶段,实施区域转未实施区域阶段递减率可降低5%左右,整体效果明显,但在不同储层条件下的适应性及应用效果具有较大差异,为研究聚合物微球在多重介质条件下的作用机理,开展了60组不同粒径聚合物微球在不同介质条件下的驱替试验,应用实验数据与现场矿场应用结合的方法系统总结微球调驱机理(渗流机理、改变流向机理),微球粒径与储层微裂缝、孔喉匹配关系,为后期施工参数优化提供依据。

关键词: 聚合物微球调驱, 渗流机理, 孔喉匹配, 多重介质

Abstract: Since 2016, Ansai oilfield has carried out polymer microsphere profile control and flooding, which has experienced three stages: pilot test, expand the scale of the test and promotion of three stages. The regional stage decline can be reduced about 5%, the overall effect is obvious, but the adaptability and application effect under different reservoir conditions are quite different, For the study of polymer microspheres in multiple media under the condition of mechanism, a group of 60 different particle size of polymer microspheres in different media under the condition of displacement test was carried out. Through the combination of experimental data and field application, the mechanism of microsphere oil displacement (percolation mechanism, change of flow direction mechanis) and the matching relationship between microsphere particle size and reservoir microfractures and pore throat are systematically summarized,which provides a basis for the optimization of construction parameters in the later stage.

Key words: Polymer microsphere flooding, Percolation mechanism, Pore?throat matching, Multiple media
