泥浆系统主要分为以下9类，其中前6类是水基系统，其次是油基和合成基系统，最后是作为循环媒介的空气、雾、泡沫或气体系统。（1）不分散系统，包括开钻泥浆、井眼内自造泥浆和其它简单处理过的泥浆系统，没有添加分散钻屑和粘土颗粒的降粘剂和分散剂。（2）分散系统，主要采 The mud systems fall into the following nine categories, of which the first six are water-based systems, the second is oil-based and synthetic-based systems, and the last is air, mist, foam or gas systems as a circulating medium. (1) Non-dispersive systems, including drilling mud, self-made mud in boreholes, and other simple-processed mud systems, without the addition of viscosity-reducing and dispersing agents that disperse cuttings and clay particles. (2) decentralized system, the main mining
