摘要
相对渗透率改善剂(RPM)是由高分子水溶性聚合物或其弱交联体系组成,其选择性堵水的机理主要有流体分流模型、孔壁效应模型等,其中吸附作用是最基本的因素。本文介绍了RPM的作用机理及应用情况,展望了RPM的研究与发展趋势。
In order to selectively reduce the moisture content of oil field,relative permeability modifiers（RPM） have been studied.It is composed of water-soluble polymer or its weak crosslinking system.The mechanism for selective water shutoff of RPM have segregated pathway mechanism and wall-effect model,and the adsorption is the most fundamental factor.In this paper,the mechanism and application of RPM system were introduced.Also the research and development tendency of RPM was pointed out.
