[Abstract]:A new organic boron crosslinking agent BX-Y, was prepared by borate and organic ligand D- fructose. BX-Y crosslinking fracturing fluid was prepared by crosslinking BX-Y with hydroxypropyl guanidine gum. The effects of synthetic conditions of BX-Y on its crosslinking properties were investigated, and the laboratory properties of BX-Y crosslinked fracturing fluids were evaluated by high temperature filtration apparatus. The experimental results show that, The optimum conditions for the synthesis of BX-Y were as follows: m (borate): m (ligand) = 1: 2, borate dosage 13% (w) (based on the mass of reaction system), catalyst dosage 2% (w), reaction time 6 h, reaction temperature 80 鈩，
