摘　　要：在钻遇含硫地层时,钻井液中需要进行除硫、控硫处理,对于聚合物钻井液,主要的方法为加入NaOH调节pH除硫和加入除硫剂。通过对聚丙烯酰胺钾盐KPAM、高粘聚阴离子纤维素PAC-HV和低粘聚阴离子纤维素PAC-LV三种常用聚合物钻井液处理剂不同条件下流变性能、水解度,分子断链情况进行测试,探究了通过NaOH调控pH和加入除硫剂WNCL两种不同的控硫方法对钻井液处理剂的影响,以便在后续的作业中筛选、研发出合适聚合物钻井液体系的除硫、控硫方法。Sulfur control treatment was needed in drilling fluid when encountering sulphur-bearing strata,for polymer drilling fluids,the main methods were sulfur remover and pH adjustment.The rheological properties,degree of hydrolysis and molecular chain breaking of four commonly used polymer drilling fluid treating agents(KPAM,PAC-HV and PAC-LV)were tested under different conditions to explore the influence of sodium hydroxide sulfur control method and WNCL sulfur removal agent on drilling fluid treating agent and the influence of WNCL on the performance of drilling fluid system.Thus,sulfur control agents could be developed according to the mechanism of action in the following operations.
