▎ 摘 要
NOVELTY - A fracturing fluid capable of effectively reducing guanidine gum adsorption on rock surface comprises 0.2-0.7 %mass guanidine gum, 0.1-0.5 %mass modified graphene oxide, 0.05-0.1 %mass discharge aid, 0.5-3 %mass clay stabilizer, 0.05-0.15 %mass pH regulator and 0.1-0.3 %mass crosslinking agent based on 100 mL water. The guanidine gum is at least one of guanidine collagen powder, hydroxypropyl guanidine gum and carboxymethyl guanidine gum. The discharge aid is perfluorononylphenol polyoxyethylene ether. The clay stabilizer is potassium chloride. The pH regulator is sodium carbonate. The crosslinking agent is 25% sodium tetraborate aqueous solution. USE - Fracturing fluid capable of effectively reducing guanidine gum adsorption on rock surface. ADVANTAGE - The fracturing fluid can avoid the blockage of channel radius between rocks after production stimulation operation, so that the flow ability of oil and gas fluid is greatly increased. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for preparation of fracturing fluid capable of effectively reducing guanidine gum adsorption on rock surface, which involves adding clay stabilizer to water, adding guanidine gum, stirring until guanidine gum is completely dispersed, adding modified graphene oxide, stirring to disperse, adding discharge aid, mixing to obtain fracturing fluid base fluid, adding pH regulator and crosslinking agent to the fracturing fluid base fluid, and stirring.
