| titleOfInvention | The preparation method of the instant drag reducer of salt tolerant |
| abstract | The present invention discloses a kind of preparation method of the instant drag reducer of salt tolerant, comprises the following steps：（1）Sorbitan monooleate is dissolved in white oil, preparation forms continuous phase；（2）Acrylic acid, the methyl propane sulfonic acid of 2 acrylamido 2, acrylamide and sorbitan monooleate APEO are dissolved in deionized water successively, are 7.5 9 with the pH value of sodium hydroxide regulation system, preparation forms dispersed phase；（3）Under stirring, dispersed phase is added dropwise in continuous phase, after being added dropwise, nitrogen is passed through, then adds initiator, the 6h of isothermal reaction 5 at 30 40 DEG C, you can.The present invention is prepared for polymer drag reducer using inverse emulsion polymerization mode, and resistance reducing effect is good, good salt tolerance, dissolution velocity is fast, the limitation that existing powder product dissolution velocity is slow, dosage is high, resistance-reducing yield is low is breached, for reducing pressing crack construction cost, fresh-water-saving resource is significant. |
