摘　　要：聚表剂是近几年发展起来的新型功能性聚合物,在各大油田和科研机构进行试验应用,聚表剂能够有效地开发水驱和聚驱过后的残余油,比一般其他化学驱效果更好,能够实现地层水油流度比控制和原油快速增溶等作用,通过提高驱替液的粘度,从而扩大波及效率。由于聚表剂具有耐高温和耐盐等特性,能够在低渗透和高温高矿化度地层中使用。本文系统地阐述了聚表剂优点特性,分析聚表剂的驱油机理,总结了聚表剂的现状与发展趋势,为以后油田开发提供建议。The polymerization agent is a new functional polymer developed in recent years, which is applied in major oilfields and scientific research institutions, and the polymerization agent can effectively develop the residual oil after water flooding and polymer flooding, which is better than the general other chemical flooding effect, and can realize the effect of rapid solubility and flow control of crude oil, improve the viscosity of displacement fluid, In order to achieve the expansion of ripple efficiency, improve the recovery rate. Because the polymerization agent has the properties of temperature-resistant and salt-tolerant, it can be used in low permeability and high salinity strata.This paper systematically expounds the advantages and characteristics of the polymerization agent, analyzes the oil displacement mechanism of the polymerization agent, summarizes the present situation and development trend of the polymerization agent, and provides suggestions for the development of the oilfield in the future.
