摘　　要：以累托石为造浆材料的基础,通过对抗高温水基钻井液处理剂进行优选,使用KPAM作为主聚物,将SLSP-Ⅱ与SMC复配使用,优化出了抗高温累托石水基钻井液的配方,并对其性能进行了评价。结果表明,该钻井液密度可达到2.1 g/cm3,具有良好的抑制性和抗盐(3%NaCl)、抗钙(0.5%CaSO4)污染能力,抗温可达200℃,在200℃的高温下维持48 h,该钻井液能满足设计要求,可以用于生产。A high temperature water base rectorite mud was formulated using KPAM as the main additive and SLSP-II and SMC as secondary additives.Laboratory evaluation showed that this mud can be weighted up to 2.1 g/cm3 and had good inhitive capacity,salt resistance(3% NaCl),calcium tolerance(0.5% CaSO4).This mud was statically maintained at 200 ℃ for 48 hours and still had satisfactory properties.
