| titleOfInvention | Resistance reducing agent for slickwater and preparation method thereof |
| abstract | The invention discloses a drag reducer for slickwater and a preparation method thereof, wherein the drag reducer is prepared by the following preparation steps: s1, uniformly mixing acrylamide, 2-acrylamido-2-methylpropanesulfonic acid, dimethyl hexadecyl allyl ammonium chloride and water to form a water-phase reaction solution; s2, uniformly mixing perfluorobutyl ethylene, an emulsifier and white oil to form an oil phase reaction solution; s3, uniformly mixing the oil-phase reaction solution and the water-phase reaction solution, dropwise adding a water-phase initiator and an oil-phase initiator at 40-60 ℃ under the condition of oxygen-free stirring, and reacting for 3-5 hours to obtain the aqueous phase initiator; the friction reducer for slickwater effectively reduces the friction resistance, the surface tension, the interfacial tension and the CST ratio, so that the friction reducer has good drainage assisting performance, anti-swelling performance and resistance reducing performance, and has the function of one agent with multiple effects; in addition, the friction reducer for slickwater is simple to prepare, convenient to mix on site, capable of effectively reducing the workload of on-site preparation, and good in market application and popularization prospect. |
