Preparation method of anhydrous organic titanium cross-linking agent concentrated solution and cross-linking type integrated suspension fracturing fluid

The invention discloses an anhydrous organic titanium cross-linking agent concentrated solution preparation method, which comprises: 1) uniformly mixing butyl titanate, triethanolamine, lactic acid and water, and heating to carry out a synthesis reaction to obtain a triethanolamine titanium lactate organic cross-linking agent; and 2) adding the triethanolamine titanium lactate organic cross-linking agent into a dialysis bag for dialysis, and concentrating and drying dialysate to obtain an anhydrous organic titanium cross-linking agent concentrated solution. The invention also provides a cross-linking type integrated suspension fracturing fluid containing the anhydrous organic titanium cross-linking agent concentrated solution. According to the anhydrous organic titanium cross-linking agent concentrated solution provided by the invention, a synthesized triethanolamine lactic acid titanium organic cross-linking agent is subjected to impurity removal through a dialysis process and then is concentrated and purifi
