Development of Extreme Pressure Anti-wear Lubricant MPA for Water Base Drilling Fluids
摘要
Abstract
An extreme pressure organic sulfur anti-wear additive has been developed for use in water base drilling fluids.Structural characteristics and extreme pressure anti-wear performance evaluation showed that the organic sulfur compound is a saturated alkane,with sulfur content as high as 35.49％,and has good extreme pressure anti-wear property.An extreme pressure anti-wear additive,MPA,was developed with a modified vegetable oil as the base oil,the extreme pressure organic sulfur anti-wear additive and surfactants.The components of MPA are all environmentally friendly.Performance evaluation showed that MPA has good compatibility with other additives,and is completely dispersible in fresh water or drilling fluids.It helps optimize the properties of drilling fluids and has excellent lubricity.关键词
