摘要
本文报道了磺甲基间苯二酚－甲醛（ＳＭＲＦ）水凝胶稳定性的研究结果。考察了油田应用环境下的一些因素（盐含量、水硬度和ｐＨ值）对该凝胶体系稳定性（成胶时间、沉淀、游离水开始排出时间和排出量）的影响。
This paper presents the results of stability investigation of a novel polymer hydrogel-sulfomethylated resorcinol /formaldehyde aqueous gel (SMRF gel) in comparison with that of resorcinol/formaldehyde aqueous gel (RF gel). The effects of some factors encountered in enhanced oil recoveries such as total dissolved salts, hardness of water quality, and pH value upon the gel stability (gelation or precipitation time, starting and amount of free water separation) are investigated. The preparation and formulation of SMRF and RF gels are described.
