泡排用表面活性剂复配实验研究

Experimental Research on Surfactant Compound for Foam Scrubbing

针对离子型表面活性剂复配体系协同效应的特点,从多种表面活性剂中选出起泡能力最好的3种表面活性剂,形成复配型泡排剂,以提高表面活性剂的起泡能力。通过系列实验得到复配最佳质量比,即乙氧基化烷基硫酸钠(AES)、十二烷基硫酸钠(SDS)、十四烷基二甲基氧化铵(DMAO)的质量之比为1∶3∶3。同时,在复配体系中引入了稳泡剂以增强其稳定性。

Ionic surfactant compound system has the characteristics of synergies. Based on the characteristics, three kinds of surfactant with best foaming ability were chosen to make up foam scrubbing agent for foam scrubbing of gas well. The foaming ability would be improved after cosurfactant added in. A series of experiments showed that m [ Sodium Alcohol Ether Sulphate （AES） ] ： m [ sodium lauryl sulfate （SDS） ] ： m [ tetradecyl dimethyl ammonium oxidation （DMAO） ] = 1 ： 3 ： 3 was the best one. Foam stabilizer was applied to improve the stability of the com- pound system.
