聚合物树脂能克服水泥类材料气密性不足、流变性能差等问题，已成为油气田化学堵漏新兴技术发展的方向。通过梳理国外主要聚合物树脂体系、树脂材料的结构和种类、评价指标，概述了树脂堵漏材料在油套管修复、支撑剂覆膜、深部调驱堵水、封堵气井带压、钻井随钻降漏失、油气井管外窜流和封堵出水层段等方面的使用现状，提出了聚合物树脂化学堵漏材料面临的问题，为国内化学堵漏技术的发展提供参考。图3参29

Polymer resin could overcome the problems of insufficient gas tightness and poor rheological properties of cement materials，and had become a new technology direction of chemical leak plugging in oil and gas fields. Through carding the main foreign polymer resin systems，the structure，types and evaluation indexes of resin materials，the application status of resin plugging materials on oil casing repair，proppant coating，deep profile control and water plugging，gas well pressure plugging，loss reduction during drilling，oil and gas well pipe outflow，water plugging and other aspects were summarized. The problems faced by polymer resin leaking materials were discussed which provided reference for the development of domestic chemical leak plugging technology.
