利用ＨＡＡＫＥＲＶ３流变仪，研究了几种国产钻头脂的高温流变学特性，建立了相应的流变方程．实验结果表明，高温时７４１１钻头脂、密封钻头脂、Ｊ７８３钻头脂三种皂类脂表现为典型的Ｂｉｎｇｈａｍ流体；非皂类脂ＺＴ９表现为典型的ＨｅｒｓｃｈｅｌＢｕｌｋｌｅｙ流体． HAAKERV3 rheometer was used to study the high temperature rheological properties of several domestic drill bits, and the corresponding rheological equations were established. The experimental results show that the three types of soap lipids of 7411 drill bit grease, seal drill bit grease and J783 drill bit grease behave as typical Bingham fluid at high temperature. The non-soap grease ZT9 shows a typical HerschelBulkley fluid.
