【摘要】 室内评价了聚合醇处理剂对聚合物钻井液防塌润滑性能、流变性、失水造壁性及抗污染能力的影响。实验结果表明 ,聚合醇能提高聚合物钻井液的抑制性 ,能大幅度提高聚合物钻井液的润滑性能 ,对聚合物钻井液有一定的稀释降粘作用 ,并能提高聚合物钻井液的高温高压稳定性 ;聚合醇在浊点温度以上时能明显降低聚合物钻井液的高温高压失水 ,并使滤饼光滑臻密。聚合醇处理剂能提高聚合物钻井液的抗钙、抗镁和抗劣质土固相侵污能力 ,使钻井液性能易于维护。文中举例介绍现场应用情况更多还原

【Abstract】 The paper studies the influence of polyalcohols JLX on the properties of polymer drilling fluid such as anti-sloughing,lubricity,rheology,loss and resistance against contamination in the lab.The results show that JLX can improve inhibitive,lubricity,HTHP stability and resistance against contamination such as Ca 2+ and Mg 2+ of polymer drilling fluid.Moreover,JLX can thin viscosity of polymer mud,and reduce filtration loss of polymer drilling fluid above the cloud point temperature.All these made the properties of polymer drilling fluid to be maintained easily.更多还原
