| titleOfInvention | Saline-based fracturing fluid thickening agent with reverse polyelectrolyte behavior and preparation method thereof |
| abstract | A saline-based fracturing fluid thickening agent with reverse polyelectrolyte behavior and a preparation method thereof belong to the technical field of oil field oil extraction additives. The amphoteric ionic polymer prepared by taking tribenzylamine, epichlorohydrin, N-dimethyl-1, 3-propane diamine, 2-acrylamide-2-methyl propane sodium sulfonate and acrylamide as main raw materials has obvious reverse polyelectrolyte behavior, can keep higher viscosity in high salinity saline, increases the viscosity of an aqueous solution in a certain mineralization degree range along with the increase of the mineralization degree, and has the advantages of strong sand carrying capacity, easiness in gel breaking and the like. The brine-based fracturing fluid generally configured from the polymer has excellent sand-carrying capacity and fracture-forming capacity. The brine-based fracturing fluid thickening agent with the anti-polyelectrolyte action has excellent brine resistance, is reliable in preparation process, and can be used for preparing the brine-based fracturing fluid thickening agent which is urgently needed at present. |
