Abstract
The invention relates to a hydrophobic oleophobic fluorine-modified water-in-water high-backflow low-damage slickwater fracturing fluid system drag reducer, belonging to the technical field of application of oil-gas field engineering chemical agents. The drag reducer is prepared by initiating dispersion polymerization of a water-soluble monomer A, a fluorine-containing monomer B, a mutual solvent C, a surfactant/dispersing agent D and an inorganic salt E in water by using a free-radical initiator F. The drag reducer maintains the characteristics of high dissolution efficiency and high drag reduction efficiency in the original drag reducer, and the drag reduction efficiency can reach 70% when the drag reducer is used in hydraulic fracturing. Meanwhile, the introduction of the fluorine-containing group lowers the affinity among the drag reducer molecules and among the reservoir rocks, and enhances the cleanup and reservoir protection properties after the hydraulic fracturing process. The drag reducer provided by the invention solves the problem that the existing drag reducer blocks the oil-gas channel and lowers the oil-gas daily yield.
Description
Technical field
