摘　　要：优选出在中原油田和川东北油田得到广泛应用的凝胶堵漏剂进行室内实验研究,分别考察了温度对低倍、中倍和高倍凝胶性能的影响。结果表明,温度对凝胶堵漏剂的影响呈现出一定的规律,温度升高,膨胀倍数也随之增加。从微观结构、平衡常数和渗透压等3个方面分析了温度影响凝胶性能的作用机理。The experimental study of gel plugging agent used widely in Zhongyuan Oilfield and northeast of Sichuan Oilfield was carried out. The effects of temperature on the performances of low, middle, and high multiple expansion gels were investigated. The results showed that the gel expanded with the increase of temperature. The mechanisms of the effects of temperature on performances of the gel were analyzed by from three aspects such as micro -structure, equilibrium constant, and osmotic pressure.
