Surfactant fracturing fluid has attracted wide attention at home and abroad in recent years due to its characteristics of no adding crosslinking agents,breaking agents and other chemical additives,and its advantages of low viscosity,good flowback ability and little damage to the reservoir.The surfactant system with low cost,simple production and less pollution should be selected when selecting fracturing fluid surfactant.Therefore,simple production process and reduced cost are the main development direction of developing surfactant fracturing fluid.In this paper,application of existing surfactants as additives in fracturing fluid was comprehensively understood.According to the existing achievements,it is necessary to further study the change of different types of surfactants on the performance of fracturing fluid,in order to cope with different geological conditions.
