| titleOfInvention | A method of it is prepared as raw material using aphthenic acids and improves oil recovery factor polymer |
| abstract | The method improving oil recovery factor polymer is prepared as raw material using aphthenic acids the present invention relates to a kind of.Aphthenic acids abundance, by the N of itself and equivalent, N dimethyl 1, amidation process occurs for 3 propane diamine, generate cycloalkanoimide of the end group containing tertiary amine, further with acrylamide substitution reaction occurs for then cycloalkanoimide of the end group of a molecule containing the tertiary amine epichlorohydrin reaction with a molecule again again, generates the acrylamide monomer of the side chain containing aphthenic acids；The monomer and a certain amount of acrylamide are copolymerized, the polymer gel with ideal washing oil and oil-displacement capacity has been prepared.Preparation method simple process and low cost is honest and clean, provides a kind of new way preparing agent for improving oilfield recovery polymer. |
