NOVELTY - Modified graphene oxide hybrid guar gum fracturing fluid system, comprises 0.05-0.3 wt.% modified graphene oxide, 0.3-0.55 wt.% guar gum, 0.3-0.5 wt.% auxiliary discharging agent, 0.3-0.5 wt.% clay stabilizer, 0.2-0.4 wt.% crosslinking agent, 0.05-0.1 wt.% gel breaker, and rest of water, where the modified graphene oxide is prepared by adding polyoxyethylene octyl phenol ether-10, sodium rosinate and sodium lauryl sulfate into water, mix well, adding monolayer graphene oxide, stir at room temperature for modification, drying and purifying for later use. USE - Modified graphene oxide hybrid guar gum fracturing fluid system. ADVANTAGE - The modified graphene oxide hybrid guar gum fracturing fluid system has improved temperature resistance by more than 20 degrees C for the unhybridized fracturing fluid. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for preparing modified graphene oxide hybrid guar gum fracturing fluid system, which involves adding guar gum to water, adding modified graphene oxide, drainage aid, and clay stabilizer according to the proportions after mixing uniformly, adding crosslinking agent and breaker to complete the fracturing fluid preparation.
