摘要
用分光光度计测试研究了磁处理对钻井液中粘土胶粒表面吸附处理剂的变化规律。结果表明,粘土胶粒经磁处理后吸附处理剂的量增加。利用热力学理论解释了吸附量增加的内在因素,提出磁处理使钻井液体系熵减小的理论。
The adsorption isotherm and apparent adsorption heat of magnetized and un-magnetized drilling fluid are studied to understand the adsorption of mud additive on clay . It is shown that magnetization can increase the adsorption of mud additive on clay , the entropy of adsorption process after magnetization is decreased .
