摘　　要：通过酰胺化反应和季铵化反应合成了一种阳离子黏弹性表面活性剂BBS,探索出其制备的最佳合成条件。考察了反离子盐水杨酸钠加量、表面活性剂BBS加量及乙二醇加量对清洁压裂液体系黏度的影响,确定了清洁压裂液体系的最佳配方,对该配方的清洁压裂液体系进行性能评价,结果表明其具有良好的耐温、耐剪切性、破胶性以及携砂性;在该清洁压裂液体系中加入乙二醇后可有效地抵御黏度降低,并从微观方面分析了表面活性剂的结构与性能的关系,探索了增稠机理。A cationic viscoelastic surfactant BBS is synthesized by amidation and quaternization,and the optimum synthesis conditions are explored.The effects of the dosage of counter-ion salt sodium salicylate,surfactant BBS and ethylene glycol on the viscosity of the clean fracturing fluid system are investigated,and the best formula of the clean fracturing fluid system is determined.The results show that the clean fracturing fluid system has good temperature resistance,shear resistance,gel breaking and sand carrying ability.Adding ethylene glycol into the clean fracturing fluid system can effectively resist the decrease of viscosity.The relationship between the structure and performance of the surfactant is analyzed from the microstructure,and the thickening mechanism is explored.
