Title:
SILICON-CONTAINING THICKENING AGENT FOR SUPERCRITICAL CO2 DRY FRACTURING FLUID AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/029459
Kind Code:
A1
Abstract:
Disclosed in the present invention is a silicon-containing thickening agent for a supercritical CO2 dry fracturing fluid. The thickening agent is composed of 18-27 g of methylcyclosiloxane, 9-13 g of vinyltriethoxysilane, 30-35 g of vinyl acetate, 9-13 g of sodium dodecyl benzene sulfonate, 3-4 g of dodecylbenzene sulfonic acid, 2.5-5.5 g of polyvinyl alcohol, 4-5.4 g of octylphenol polyoxyethylene ether, 2.5-3.6 g of lauryl sodium sulfate, 3-3.1 g of ammonium persulfate and 89-155 g of deionized water. The product of the present invention is suitable for industrial application and has a strong thickening ability. Further disclosed in the present invention is a method for preparing the silicon-containing thickening agent for a supercritical CO2 dry fracturing fluid.
