Rheological Property of the Regenerable Polyhydroxy Alcohol Fracturing Fluid System

Abstract:

According to the characteristic of polyhydroxy alcohol fracturing fluid system, the regeneration of the system was investigated for the first time. A stable organic boron crosslinking poly (vinyl alcohol) regenerable polyhydroxy alcohol fracturing fluid system was prepared, and the rheological property of the polyhydroxy alcohol fracturing fluid system with different regenerable times was also researched. The effect of regenerable times on the rheological property of the system was studied. The results indicated that the aims of gel breaking and regeneration can be achieved by regulating its pH value and controlling its crosslinking degree. With the increment of the regenerable time, both the temperature resistance and shearing resistance performances were decreased, and the viscoelasticity of the gel was also reduced.
