| titleOfInvention | A kind of acid liquid drag reducer and preparation method thereof |
| abstract | The invention discloses a kind of acid liquid drag reducer and preparation method thereof.The present invention is to weigh the methyl propane sulfonic acid of 2 acrylamido of monomer 2 in beaker, adds deionized water dissolving, then adds piece alkali, system pH is adjusted into 8 10；Add monomeric acrylamide and long chain cation monomer, in the case of logical inert gas, stirring, regulation bath temperature react to add initiator after initiation reaction temperature, transparent blob of viscose is made, finally by transparent blob of viscose craft stripping and slicing, dry, crush, and 100 mesh sieves point, powdered acid solution drag reducer is made.The synthetic method of the present invention is simple, and raw material are easy to get, and reduce cost；Acid solution drag reducer resistance-reducing yield produced by the present invention is up to 65%, reduces pump pressure, reduces line losses, extends the service life of equipment；The temperature tolerance and compatibility of acid solution drag reducer are good, while also have certain slow effect. |
