目前,金刚石钻探生产中大量使用的皂化溶解油、癸脂酸钠、S—S润滑剂、YZ—84润滑剂和松香酸钠等阴离子型脂肪酸钠类润滑减阻剂,虽均具有良好的润滑性能,在一般地层中显示出较好的作用效果,但当遇到污染地层或有污染的水时,由于所含钙镁离子与其中的主要成分脂肪酸钠生成不溶于水的脂肪酸钙和脂肪酸镁沉淀,使润滑剂破乳,降低甚至完全失去其原有的润滑性能。另外,某些润滑剂在使用中还容易结垢,造
At present, large quantities of saponified dissolving oils, sodium caprate, S-S lubricants, YZ-84 lubricants and sodium rosinate, which are widely used in diamond drilling production, have good lubricating properties Performance, in the general stratum shows good effect, but in the case of contaminated formation or contaminated water, due to the contained calcium and magnesium ions and the main component of sodium fatty acid into water-insoluble fatty acid calcium and fatty acid magnesium Precipitation, the lubricant demulsification, reduce or even completely lose its original lubricating properties. In addition, some lubricants are also easy to scale in use, made
