摘　　要：采用差热分析法和水溶液密封老化后的特性粘度法，全面系统地研究了国内外十种降滤失剂的耐温性。通过差热分析和水溶液老化后的特性粘度测出了各种降滤失剂的耐温次序和分解温度。所获得降滤失剂的耐温次序大体与在钻井液中的情况一致，而耐受温度的最高限却与在钻井液中的情况不符，差热分析法高出甚远而特性粘度法则偏低。The temperature resistance of 10 kinds of domestic and overseas fluid loss additives is systematically researched by use of DTA and inherent viscosity of additives in aqueous solution after aging. The order of temperature resistance and decomposition temperature of fluid loss additives is obtained. The results show that the order of temperature resistance of these additives in aqueous solution is roughly consistent with that in drilling fluids, but the decomposition temperature tested by DTA is much higher than that in drilling fluids, the decomposition temperature measured with inherent viscosity is on the low side. In addition, the decomposition mechanism is discussed in this paper.
