| titleOfInvention | A kind of fracturing fluid drag reducer and preparation method thereof |
| abstract | The invention discloses a kind of fracturing fluid drag reducer and preparation method thereof, this fracturing fluid drag reducer contains polymer, stabilizer, water-soluble inorganic salt and the deionized water that water-soluble monomer is formed, wherein, described fracturing fluid drag reducer does not comprise organic solvent and surfactant, described water-soluble monomer is acrylamide and anionic monomer, and described stabilizer is the compound system of polyglutamic acid and polyethylene glycol oxide.The fracturing fluid drag reducer that the present invention provides has good environmental-protecting performance, at room temperature can be with storage-stable more than 3 months, and drag-reduction effect is obvious, drag reducing efficiency may be up to 78.5%, fracturing fluid drag reducer cost is cheap, raw material is easy to get and instant effective, and the dissolution time in clear water and NaCl is less than 10 minutes. |
