摘　　要：以自制季铵盐表面活性剂与水杨酸钠水溶液按一定比例混合,制备了清洁压裂液。对该压裂液的热稳定性、滤失性、破胶性和对地层伤害性进行了室内评价。结果表明,该清洁压裂液粘弹性好,能自动破胶无需使用破胶剂,对地层伤害小,配制简单,易于现场应用。A clean fracturing fluid was prepared by mixing a self-made quaternary ammonium surfactant with sodium salicylate solution in a special ratio.The heat stability,filtration,gel breaking property and formation damage of the fracturing fluid were evaluated in laboratory.The results showed that the fracturing fluid had good elasticity,broke gel automatically and had little damage to formation.It was easy for the fluid to be pre- pared and used in fields.
