Embodiment 1
[0061] A preparation method of guar gum fracturing fluid gel system, the steps are as follows:
[0062] (1) Dissolve isopropanol and triethanolamine in ethylene glycol according to the mass ratio of 1:2 and mix evenly. The mass ratio of ethylene glycol to boric acid is 20:1. According to 1:2 (isopropanol: boric acid ) to a mass ratio of boric acid, adjust the temperature to 65°C and continue to stir until the boric acid is completely dissolved to form a mixed solution. According to the mass ratio of 1:20 (tetraisopropyl titanate: mixed solution), tetraisopropyl titanate was added to the above mixed solution, the temperature was raised to 75°C, and a stable organic Boron-titanium crosslinker solution.
[0063] (2) prepare concentration 0.3% hydroxypropyl guar gum solution and make it fully swell, add 0.1% average particle diameter and be the nano-silica (Shanghai Naiou Nano Technology Co., Ltd., 99.9%) containing active hydroxyl of 20nm and mix Evenly, the nanoparticles are c...

[0065] A preparation method of guar gum fracturing fluid gel system, the steps are as follows:
[0066] Propanol and triethanolamine are dissolved in ethylene glycol according to the ratio of 1:2 and mixed evenly. The mass ratio of ethylene glycol and borax is 15:1. Add borax according to the ratio of 1:2 (propanol: borax), adjust The temperature is 65°C and the stirring is continued until the borax is completely dissolved to form a mixed solution. Add butyl titanate to the above mixed solution at a mass ratio of 1:30 (butyl titanate: mixed solution), raise the temperature to 75°C, and continue the reaction for 3 hours to obtain a stable organic boron titanium crosslinking agent solution .
[0067] Prepare concentration 0.25% hydroxypropyl guar gum solution and make it fully swell, add 0.12% average particle diameter and be the nano-titanium dioxide (Aladdin reagent (Shanghai) Co., Ltd., anatase, hydrophilic lipophilic type, 99.8%) and mix uniformly, so that the nanoparticle...

[0069] A preparation method of guar gum fracturing fluid gel system, the steps are as follows:
[0070] Dissolve glycerol and triethanolamine in ethylene glycol at a ratio of 1:3 and mix evenly. The mass ratio of ethylene glycol to boric acid is 18:1. Add boric acid at a ratio of 1:2 (glycerol: boric acid) , adjust the temperature to 65°C and keep stirring until the boric acid is completely dissolved to form a mixed solution. Add tetraisopropyl titanate to the above mixed solution at a ratio of 1:30 (tetraisopropyl titanate: mixed solution), raise the temperature to 75°C, and continue the reaction for 3 hours to obtain a stable organic boron titanium Crosslinker solution.
[0071] Prepare concentration 0.15% hydroxypropyl guar gum solution and make it fully swell, add 0.08% diameter and be 50nm, the nano-cellulose (Jiangsu North Century Cellulose Material Co., Ltd.) that length is 400nm and mix homogeneously, make nanoparticle be dispersed in completely In the guar gum solut...
