摘　　要：考察了羧甲基淀粉(CMS)对钻井液性能的影响、CMS 的抗温能力与抗盐抗钙能力,介绍了 CMS 的现场应用情况,并对 CMS 的作用机理进行了讨论。研究结果表明,CMS 适用于各种水基钻井液体系,是一种抗盐性能极好的降失水剂,有一定的抗钙能力,可抗温至130℃,不发酵。The influence of carboxymethylstarch(CMS) on properties of various drilling fluids is investigated in laboratory.It is shown that CMS reduces obviously the filter losses,improves the cake properties,heat resistance (to 120-130℃),and salt- and calcium-tolerance of all water-base drilling fluids studied.The field uses of CMS are illustrated in terms of 3 typical examples of drilling practise (in 3 wells).The action mechanizms of CMS in drilling fluids are also discussed.
