Embodiment 1
[0013] An anti-swelling stabilizer for fracturing, comprising the following components by mass percentage: 25% polydimethyldiallyl ammonium chloride, 10% sodium chloride, and 5% alkylphenol polyoxyethylene ether and water 60%.
[0014] The preparation process of the anti-swelling stabilizer for above-mentioned fracturing is specifically as follows: after adding 60 g of water, 25 g of polydimethyldiallyl ammonium chloride, and 5 g of alkylphenol polyoxyethylene ether into a stirred reactor, Raise the temperature to 70°C for 1 hour, then cool to room temperature, then add 10 g of sodium chloride, stir for 1 hour to obtain an anti-swelling stabilizer.
Embodiment 2
[0016] An anti-swelling stabilizer for fracturing, comprising the following components by mass percentage: 28% polytrimethylallyl ammonium chloride, 15% potassium chloride, dodecyl dimethyl benzyl chloride Ammonium chloride 10% and water 47%.
[0017] The preparation process of the anti-swelling stabilizer for above-mentioned fracturing is specifically as follows: add 47g water, 28g polytrimethylallyl ammonium chloride, 10g dodecyldimethylbenzyl chloride into a reactor with stirring After mixing the ammonium, raise the temperature to 60°C for 2 hours, then cool to room temperature, add 15 g of potassium chloride, stir for 1.5 hours to obtain an anti-swelling stabilizer.
Embodiment 3
[0019] An anti-swelling stabilizer for fracturing, comprising the following components by mass percentage: 30% poly 2-hydroxypropyl-1,1-N-dimethylammonium chloride, 13% potassium chloride, alkane Base phenol ethoxylate 5% and water 52%.
[0020] The preparation method of the above-mentioned anti-swelling stabilizer for fracturing, the specific process is as follows: add 52g water, 30g poly 2-hydroxypropyl-1,1-N-dimethylammonium chloride, 5g After the alkylphenol polyoxyethylene ether was mixed, the temperature was raised to 50°C for 3 hours, then cooled to room temperature, and 13 g of potassium chloride was added, and the anti-swelling stabilizer was obtained after stirring for 2 hours.
