【摘要】：针对目前钻井液常用植物油润滑剂润滑持效性差以及抗温性能差的问题,以油酸和聚醚胺为原料,经酰胺化反应,制得钻井液润滑剂NH-HPL。性能评价结果表明:在常温下,5%膨润土浆中加入1%NH-HPL,润滑系数可降低92.2%,抗温达160℃,荧光级别为1级,EC_(50)值为9.57×10~4mg/L,没有生物毒性,对钻井液流变性和滤失性无明显影响。
[Abstract]:Aiming at the problems of poor lubrication and poor temperature resistance of the common vegetable oil lubricants used in the drilling fluid, oleic acid and polyether amine are used as raw materials, and the drilling fluid lubricant NH-HPL is prepared through the deamination reaction. The results of the performance evaluation show that 1% NH-HPL is added to 5% bentonite slurry at normal temperature, the lubricating coefficient can be reduced by 92.2%, the anti-temperature is 160 鈩，
