摘　　要：综述了国外油井挤注法防垢技术的进展。简介了技术原理及分类:吸附法,沉淀法及其他方法。较详尽地介绍了沉淀法的物理化学原理、所用防垢剂及沉淀增强剂、置放工艺、技术发展及应用。对吸附法的介绍重点是增加吸附量的方法。其他方法有乳液挤注法等。现场应用包括英国北海、沙特阿拉伯、中国胜利等油田。The overseas developments of scale inhibitor（SI） squeeze treatments for oil production wells are reviewed. The principles and the classification of the squeeze treatments are described concisely. For SI precipitation squeezes, the physicoehemical principles, scale inhibitors,precipitation enhancing additives, delivery technologies, technologic developments, and applications are presented in some detail. SI adsorption squeezes are stated with adsorption enhancing additives and means stressed. SI invert emulsion squeeze and others are stated also. Cases of SI squeeze treatments in British North sea,Saudi Arabia and Shengli,China,are presented.
