一、前言随着金刚石钻进,特别是绳索取芯钻进方法的推广和应用,以及钻孔向深部发展,对冲洗液提出了更高的要求。八十年代中后期,我国的石油、地矿、冶金等系统先后研制出了相应的润滑剂产品,我们在广泛收集国内外有关资料,考察分析国内现有产品优缺点的基础上,经过反复计算和科学试验,利用植物油下脚料研制出了ML—1润滑剂。这种润滑剂,在室内进行优选配方的基础上,全面系统地进行了性能评价,并通过4个钻孔、进尺二千多 I. INTRODUCTION As the diamond drilling, especially the promotion and application of the rope coring drilling method, and the drilling to the deep development, put forward higher requirements for the flushing fluid. In the late 1980s, China’s oil, mining, metallurgy and other systems have developed a corresponding lubricant products, we extensively collect relevant information at home and abroad, study the advantages and disadvantages of existing products based on the analysis, after repeated calculations And scientific experiments, the use of vegetable oil scraps developed ML-1 lubricant. This lubricant, based on the preferred recipe in the room, performs a comprehensive and systematic evaluation of the performance and, through four holes, into the more than 2,000
