| titleOfInvention | Multi-component slickwater drag reducer and preparation method thereof |
| abstract | The invention provides a multi-component slickwater drag reducer and a preparation method thereof. The multi-component slickwater drag reducer is prepared by compounding a main component of a synthesized modified polyacrylamide water-soluble polymer containing sulfonic groups and a dissolution assisting component containing a surfactant, wherein the main component comprises the following components in parts by weight: the weight portion of the solubilizing component is (7.5-8.5): (1.5-2.5). The multi-component slickwater drag reducer has excellent solubility; extremely high temperature resistance, and the temperature resistance can reach 200 ℃; extremely strong shear resistance; the fluidity is very good, the friction resistance is very small, and the resistance reduction rate can reach 90 percent; the modified fracturing fluid has good compatibility with reservoir fluid and common fracturing fluid additives; extremely low corrosivity to downhole tools and strings; the application is wide; the cost is low. |
