摘要：An oil-phase-free triple-play slick water concentration system, is characterized by first synthesizing a water-soluble dispersion polymer drag reducer A; and then preparing an inorganic salt solution B, under mechanical agitation, of high-performance water-soluble fluorocarbon surfactant and a water-soluble of high-performance small molecule or macromolecule clay stabilizer containing quaternary ammonium ions; and finally, the aqueous inorganic salt solution B is slowly added to the drag reducer dispersion A, wherein the ratio of the aqueous inorganic salt solution B and the dispersion A is 20-80:80-20.
