ＪＬＸ水基防塌润滑剂是一种环境可接受的非离子型水基钻井液处理剂，实验室考察了这种防塌润滑剂在粘土颗粒表面上的吸附特性。实验从吸附速度、吸附等温线形状、无机盐种类及氯化钾加量的变化对吸附量的影响等方面，获得了一些规律性的认识，如动态平衡的吸附时间为２ｈ，ＪＬＸ的吸附量随无机盐加量的增加而增加，吸附等温线形状基本符合Ｌａｎｇｍｕｉｒ等温吸附，ＪＬＸ在水溶液中与ＫＣｌ复配有利于前者的吸附等。这些认识为进一步研究ＪＬＸ水基防塌润滑剂的作用机理奠定了基础。
JLX water-based anti-collapse lubricant is an environmentally acceptable non-ionic water-based drilling fluid treatment agent, the laboratory investigated the anti-collapse lubricant adsorption characteristics of clay particles on the surface. Experiments from the adsorption speed, adsorption isotherm shape, inorganic salts and potassium chloride dosage changes on the amount of adsorption and other aspects of the understanding of some regularity, such as dynamic equilibrium adsorption time of 2h, JLX adsorption capacity With the increase of inorganic salt, the adsorption isotherm shape is basically in accordance with Langmuir isothermal adsorption, JLX complex with KCl in aqueous solution is conducive to the former adsorption. These understandings provide the basis for further study on the mechanism of JLX water-based anti-collapse lubricant.
