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。
The commonly used vegetable oil drilling fluid lubricants have poor long-acting lubrication and poor temperature resistance.For this reason,a environmentally friendly efficient drilling liquid lubricant NH-HPL for was prepared by the amidation of oleic acid and polyether amine. Its performance evaluation results show that,at room temperature,adding 1% NH-HPL to 5% bentonite slurry,the lubrication coefficient of the bentonite slurry can be reduced by 92. 2%,its temperature resistance can reach to 160 ℃,fluorescence level is 1,and EC_（50） value is 9.57 × 10~4mg/L. Lubricant NH-HPL has no toxicity,and it has no obvious influence on the rheology and fluid loss of drilling fluid.
