摘　　要：在室内全面评价了重庆市两个厂家生产的六种商品羧甲基淀粉(CMS)作为泥浆处理剂(降失水剂)的性能。Five commercial carboxymethyl starches(CMSs) of different substitution degree and processing technology, together with a cationic starch, are evaluated in laboratory tests on filtrate loss control, rheologic behavior, salt and calsium tolerance, and thermal resistance of the mud treated. Besides of the cationic starch, each of the CMSs tested is superior to others in one or another property. Most of these CMSs are being successfully used in drilling practice in Sichuan Gas Fields as filtrate loss controller.
