Advances in Preparation and Uses of Drilling Fluid Additives in China in 1999—2000

本文介绍了国内近两年来钻井液处理剂的研究与应用进展 。

This review artical introduces 21 newly prepared or developed (and put into field uses) chemical additives for drilling fluids (water based in general) published in Chinese periodicals in 1999 and 2000 under following headings:①synthetic polymers(11 filtrate loss reducers, 4 inhibitory/anticaving agents, and 2 viscosity reducers); ②modified natural materials(3 modified starches, 3 modified celluloses, and 4 others); recycled wastes(4). For every chemical agent the chemical composition, the prominent performance properties, and the field results are presented concisely.
