Abstract
The present invention discloses a supercritical CO2 thickener for shale gas reservoir based on hollow mesoporous silica nanoparticles and a preparation method thereof, and relates to the technical field of oil and gas field development. The preparation method of the thickener includes: reacting a monomer consisting of fluoroacrylate, styrene and vinyl acetate in a molar ratio of 3-5:1-2:1-2 with 2%-5% of a total weight of hollow mesoporous silica nanoparticles with carbon-carbon double bonds under the action of an initiator to obtain the thickener.…
