阴离子表活剂压裂液是新型清洁压裂液,为了深入了解该压裂液的作用机理,进行了多项实验研究,包括压裂液的配方优化,液体配制,耐温抗剪切性能,黏弹性及悬砂性,压裂液的滤失及岩心伤害实验,压裂液的破胶特性等等。实验结果证明,压裂液黏度可调性强,在100℃条件下,压裂液的黏温、黏时性能及悬砂性好,压裂液遇到原油破胶,温度越高破胶越彻底,破胶后无残渣,伤害小。
Anionic surfactant fracturing fluid is a new type of clean fracturing fluid. In order to understand the mechanism of action of fracturing fluid, a number of experimental studies have been carried out, including formulation optimization of fracturing fluid, formulation of fluid, temperature and shear resistance, Viscoelasticity and suspended solids, fluid loss and core damage test of fracturing fluid, breaking property of fracturing fluid and so on. Experimental results show that the viscosity of the fracturing fluid is adjustable. Under the condition of 100 ℃, the viscosity of the fracturing fluid, the viscous performance and the suspensibility of the fracturing fluid are good. The fracturing fluid encounters the breaking of crude oil and the higher the temperature, Thoroughly, no residue after breaking gel, less damage.
