无硫磷含钼极压润滑剂的制备及其适用性评价

Preparation of sulfur-phosphorus-free molybdenum-containing extreme pressure lubricants and evaluation of its applicability

本文研制出两种能同时满足生物毒性和生物降解性的不含硫、磷的环保型非活性含钼极压润滑剂,该剂可同时满足极压润滑和抗磨效果均好的双重效果。将其在多个常用的水基钻井液体系中进行性能评价,发现SLIP-M在PLUS-KCl体系、EZFLO体系和硅酸盐体系均表现出良好的配伍性、较好的润滑能力和突出的提高抗磨能力,具有多体系适用的特点,SLIP-M在现场应用时,有效解决了现场托压、起下钻遇阻的问题。

In this paper,two sulfur-phosphorus-free environmentally friendly non-reactive molybdenum-containing extreme pressure lubricants which can meet both biological toxicity and biodegradability,have been developed to achieve multiple effects of good extreme pressure lubrication and good anti-wear effect.The performance of SLIP-M was evaluated in several commonly used water-based drilling fluid systems,and it was found that SLIP-M showed good compatibility,good lubricating ability and outstanding anti-wear ability in PLUS-KCl system,EZFLO system and silicate system,with the characteristics of multi-system applicability,and SLIP-M effectively solved the problems of pressure-holding and start-up and down-drilling obstruction in the field application.
