    摘要:A combo hydraulic fracturing fluid concentrate, is characterized by 1) firstly preparing “water-in-water” dispersion polymer drag reducer A, which is synthesized via dispersion polymerization to obtain water-soluble macromolecular colloidal particles dispersed in an aqueous solution of inorganic salts; 2) secondly, adding a dispersion B, which is a polymeric viscosifier, having shear-thinning properties, dispersed in aqueous inorganic salt solution; wherein the percentage by weight of drag reducing agent to viscosifier dispersion B is 20-80:80-20.
