无铬降粘剂GHm的研究与应用（Ⅰ）

Research and Application of Chromium-Free Viscosity Reducer GHm for Drilling Fluid (Ⅰ)

腐植酸在螫合促进剂存在下，通过Ｍｎ－Ｍｎｎ－１复合离子络合、催化磺化、复合Ｎ－Ｐ多元增效剂制成降粘剂。从ＩＲ．ＤＴＡ与粘土、钻屑的吸附性能，粘土悬浮液中粒度分布，Ｚｅｔａ电位等对ＧＨｍ特性进行了讨论。

A new brand of viscosity reducer is prepared from humic acid by completing ofcomposite ion Mn-Mn-L and catalytic sulfonation in the presence of a chelating promoter and a composite N-P multi-element Synergist. Discussion hat been mace concerning the effect of adsorption property of IR,DTA, clay and drill cuttings .penicle distribution of clay suspension and Zeta electric Potentinl.
