钻井液润滑性能是影响钻井速度和井下安全的关键因素之一。本论文介绍了钻井液润滑材料对比评价实验仪器及方法，对钻井液体系中常用润滑材料的性能进行对比试验分析，选择效果最好的润滑剂品种和最优的复配方案，制定合理的配套润滑技术措施。 The lubricating Performance for drilling fluid become one of the key factors which affect drilling speed and downhole safety. The thesis recommends instruments and methods on comparison and evaluation of drilling fluid lubricant. A series of comparison and evaluation tests have been made to select the most effective materials and get the optimum combination formula and reasonable lubricant technical measures.
