  • GUAR GUM FRACTURING FLUID GEL AND GUAR GUM FRACTURING FLUID SYSTEM WITH REDUCED pH DEPENDENCE, AS WELL AS PREPARATION METHOD AND APPLICATION THEREOF
    Publication number: 20240368459
    Abstract: A guar gum fracturing fluid gel and a guar gum fracturing fluid system with reduced pH dependence, a preparation method and an application thereof are disclosed. The fracturing fluid gel includes 0.01-0.2% of nanomaterial, 0.1-0.5% of guar gum, 0.1-0.5% of organic boron-titanium crosslinker and a remaining amount of water. The fracturing fluid gel is more stable in network structure, tolerant of different temperatures and has good shear resistance. A preparation method and an application of the fracturing fluid gel are also provided. In the guar gum fracturing fluid system, the dependence on pH level is reduced, thereby alleviating the damage caused by a high pH value to a reservoir.
