一种钻井液用无荧光润滑剂的研究与应用

摘要

Introducing a new lubricant RH for muds. Natural plant oil is the main raw material. The results which come from fluorescence analysis,EP lubricating coefficient analysis,foaming rate analysis and com-patibility analysis,investigate that RH has a good lubricant performance,is of non-fluorescent,low blister-ing area,high temperature resistance and good compatibility with muds. It has been field tested in North-east, showing that RH is of wonderful lubricating and non-fluorescent. It brings a fantastic construction result.%介绍了一种以天然植物油为原料的钻井液用润滑剂RH.通过荧光、极压润滑系数、起泡率和配伍性等实验分析表明,RH具有优良的润滑性,同时无荧光、起泡率低和耐高温,对钻井液流变性能无影响.RH已在中石化东北区块完成了现场实验,取得了理想的施工效果.
