Laboratory Study of Weak Acid Fracturing Fluid

At present, most of the fields have entered the stage with high moisture content. So fracturing as an important stimulation is particularly important. Through a lot of theoretical analysis and experimental studies. The water insoluble matter of modified guar gum we composed is much lower than before. It has a better tackifier performance. The GHPG can cross-link with cross-linker in weakly acidic conditions. So it can avoid the damage of the fracturing fluid to the formation of desensitization. And the fracturing fluid has higher strength, stability. It has a better gel breaking performance after which the viscosity is 1.87 mPa·s. So it can reduce the damage to reservoir permeability greatly
