摘　　要：要提高深井超深井、大斜度定向井、水平大位移井等高难度复杂井的开发效率,必须降低钻井、下套管和电测等作业过程中的井下摩阻系数和扭矩大小。对于钻井液来说,减小摩阻系数和扭矩大小最快捷有效的方法是在体系加入润滑剂,提高其润滑性能。综述了国内外高性能钻井液用润滑剂的种类、机理和应用进展,并评述了各自的优缺点,分析了现有润滑剂技术局限性与发展趋势,并预测了未来改性废弃植物油类等润滑剂的研究前景与方向。To improve the development efficiency of high difficulty and complex wells such as deep and ultra deep wells,high inclination directional wells,and horizontal large displacement wells,it is necessary to reduce the downhole friction coefficient and torque during drilling,casing,and electrical logging operations.For drilling fluids,the quickest and most effective way to reduce friction coefficient and torque is to add lubricants to the system to improve its lubrication performance.This article summarizes the types,mechanisms,and application progress of lubricants for high-performance drilling fluids in China,and evaluates their respective advantages and disadvantages.It analyzes the limitations and development trends of existing lubricant technologies,and predicts the research prospects and directions of modified waste vegetable oils and other lubricants in the future.
