摘要：A multifunctional slick water concentrate, is obtained by “W/W” dispersion polymerization at elevated temperature, wherein water-soluble monomer A1, water-soluble fluorocarbon surfactant A2, water-soluble quaternary ammonium clay stabilizer A3, water-soluble dispersant A4, water-soluble free radical initiator A5, inorganic salt A6 and water A7, is first formed a homogeneous system under mechanical agitation; wherein, the percentage of the weight of each respective component, relative to the total weight of the reaction system, is as the following: water-soluble monomer A1: 5.0-20.0%; water-soluble fluorocarbon surfactant agent A2: 0.1-5.0%; water-soluble quaternary ammonium clay stabilizer A3: 0.1-20.0%; water-soluble dispersant A4: 0.1-10.0%; water-soluble radical initiator A5: 0.000001-0.100%; inorganic salt A6: 15.0-40.0%; water A7: remainder.
