- Abstract
In order to study the mechanism of the formation of micelle system by the combination of propylene bis (octadecyl dime thylammonium chloride) (abbreviated as 18-3-18),potassium chloride and sodium salicy-late,and to find the viscosity The best ratio of elastic surfactant (VES) fracturing fluid system. In this paper, scanning electron microscope (SEM) is used to observe the microstructure of different components mixed with viscoelastic surfactant, and the viscosity is measured with a viscometer. Find the best ratio, a nd add polyoxyethylen e to hope to further improve its viscoelasticity. The results show that when the concentration of 18-3-18 is fixed at 2 wt %,the potassium chloride content is adjusted to 7 wt %, the sodium salicylate content is at 0. 6 wt %, the formed VES fracturing fluid has the best viscoelasticity, and after adding 0. 1 wt% polyoxyethylene, the viscosity of the system has increased significantly, and the effect is better at high shear rate.
