摘　　要：实验分别选取了塔里木油田低、中、高密度具有代表性的几口深井的水基磺化钻井液,使用高温高压流变仪Fann 75,对高温高压下温度及压力对该钻井液性能的影响进行了研究。结果表明,在180℃以下,表观黏度随温度升高而降低,在180～230℃范围内表观黏度随温度升高而升高;塑性黏度在50～230℃范围内随温度升高而降低;动切力在100℃以内随温度升高而降低,在100～230℃范围内随温度升高而升高;压力和温度同时变化时,水基磺化钻井液各流变参数的变化规律与温度对各参数的影响规律相同,温度是影响钻井液流变性的主要因素。Effects of temperature and pressure to rheology of drilling fluid are researched by FAN75, which is based on kinds of low middle and high densities sulfonated drilling fluid in Tarim oilfield.The experimental results show that when temperature and pressure change at the same time, rheology of the drilling fluid changes only with temperature, and the apparent viscosity drops down with temperature rises up below 180℃, rise simultaneously at 180-230 ℃, also the plastic viscosity drops down with temperature rises up, and the yield point drops down with temperature rises up within 100 ℃,both rise at 100-230 ℃.
