| titleOfInvention | Preparation method of biomass modified polyacrylamide for oil displacement and recovery |
| abstract | The invention relates to a preparation method of biomass modified polyacrylamide for oil displacement and extraction, belonging to the technical field of oil extraction engineering. The invention provides a polyacrylamide oil displacement agent which is easy to decompose by ozone oxidation, aiming at the problem of low flux caused by high viscosity of polymer wastewater in the membrane filtration process in the polymer oil extraction wastewater treatment process of oxidation and membrane filtration. |
