老油田精细挖潜是我国原油稳产的关键手段，主力老油田总体处于“双高”开发中后期，稳产难度大，尤其是高温高矿化度地层老油田。现有调堵剂技术很难解决高含水和地层非均质性等问题。基于高温高矿化度地层的苛刻条件及现有技术的局限性，文章介绍了改性聚丙烯酰胺凝胶、二氧化硅聚合物凝胶、缓交联聚合物凝胶和生物基调堵凝胶体系的国内外研究和应用情况，着重综述了缓交联聚合物凝胶体系和缓交联技术及影响因素。PEI 聚合物凝胶调堵剂可靠性强，应用范围更广；然而随着环保政策收紧，生物基聚合物凝胶调堵剂是未来主要发展趋势。

Fine tapping of old oil fields is a key means of stabilizing the crude oil production. The main old oil fields are generally in the middle and late stages of "double high" development，with great difficulty in stabilizing production，especially in high temperature and high salinity formations. The existing plugging agent technology is difficult to solve problems such as high water content and formation heterogeneity. Based on the harsh conditions of high temperature and high salinity formation and the limitations of existing technologies，this paper introduces the research and application of modified polyacrylamide gel，silica polymer gel，slow cross-linking polymer gel and biological based profile control and plugging gel system at home and abroad，and focuses on the slow cross-linking polymer gel system，slow cross-linking technology and influencing factors. Among the above gels，PEI polymer gel has strong reliability and wider application range，however，with tightening of environmental protection policies，bio-based polymer gel plugging agent is the main development trend in the future.
