水基钻井液用环保型润滑剂的研究综述

Research Review of Environmentally Friendly Lubricants for Water-based Drilling Fluids

本文分析了非常规井水平段钻进过程中容易出现高摩阻和高扭矩的原因,综述了影响润滑剂润滑性能的因素,润滑剂的国内外研究进展,以及润滑剂的作用机理。针对非常规井水平段钻井液的润滑性能较差的问题,指出了当下以及今后钻井液的润滑剂要解决的问题。

This article elaborated on the necessity of vigorously developing unconventional wells in China,analyzed the reasons for high friction and high torque during the horizontal drilling process of unconventional wells,summarized the factors which affected the lubrication performance of lubricants,as well as the mechanism of lubricant action and research progress in China and abroad.In response to the problem of poor lubrication performance of drillingfluid in the horizontal section of unconventional wells,the current and future problems to be solved for drillingfluid lubricants were pointed out.
