Zusammenfassung:The present invention relates to a guar gum fracturing fluid gel and a guar gum fracturing fluid system with reduced pH dependence, as well as a preparation method and an application thereof. 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 and good in temperature and shear resistance. The present invention further provides a preparation method and an application of the fracturing fluid gel. According to the guar gum fracturing fluid system, the dependence on pH is reduced, and the damage degree of the high pH value to a reservoir is alleviated.
