【摘要】 聚合醇JLX为水基防塌润滑剂,是一种环境可接受的非离子型钻井液处理剂。本文研究了JLX在安丘评价土上的吸附特性,分析并讨论了吸附平衡时间、吸附等温线的形状、无机盐种类及其加量和温度对吸附量的影响,结果发现,在30℃条件下,JLX在安丘评价土上的吸附平衡时间为2 h,而且其吸附等温线基本符合Langmuir型;在浊点以下温度时,JLX吸附量随着温度的增加而有所下降,但达到浊点温度时,吸附量随温度的升高而增大,当温度超过浊点30℃左右时,吸附达到一新的平衡而后趋于平衡;当温度高于JLX浊点时,随着JLX浓度的增加,其吸附量增加;无机盐的存在有利于JLX的吸附,但与无机盐的种类有关。更多还原

【Abstract】 Polyoi water-based drilling fluid is an alternative to oil-based mud. One of the shale inhibition mechanisms is that the forming of the composite by the interaction between polyol and K + s on the surface of clay, inhibiting the hydration of clay. The paper studied the adsorption of JLX, which is a polyol on clay. Tests showed that the adsorption balancing time is 2 hours and isothermal line agrees with Model Langmuir. Below the cloud point temperature, the adsorption decreases with the going up of temperature , while over the cloud point, it increases with the going up of temperature and content of JLX, salt also benefit the adsorption.更多还原
