| titleOfInvention | Acrylamide graft copolymer oil-displacing agent and preparation method thereof |
| abstract | The invention relates to an acrylamide graft copolymer oil-displacing agent and a preparation method thereof. The acrylamide graft copolymer oil-displacing agent is water-soluble, is low in using amount and has relatively high thickening property and good temperature resistance and shear resistance. The invention adopts the technical scheme as follows: the acrylamide graft copolymer oil-displacing agent comprises the following raw materials and monomers in mass percentages: with gram as a mass unit, 51.5-58.8% of AM (acrylamide), 40-45.5% of AA (acrylic acid), 0.1-1.5% of APEG (allyl polyethylene glycol ether) and 0.1-1.5% of KGM (konjac glucomannan). The preparation method of the acrylamide graft copolymer oil-displacing agent comprises the following steps: adding the KGM into a reactor, adding deionized water, and stirring for 30 minutes at the constant temperature of 30 DEG C so as to sufficiently swell the obtained mixture; sequentially adding the AM, the AA and the APEG; regulating PH to 6-8, inflating nitrogen for 10 minutes, and adding an initiator ceric ammonium nitrate; and reacting for 8 hours at 35-55 DEG C, and roughly separating, refining, drying and pulverizing a product to obtain a polymer AM/ AA /APEG/ KGM. The viscosity retaining rate of a 0.1wt% solution of the acrylamide graft copolymer oil-displacing agent at 100 DEG C is as high as 91.3%; and the acrylamide graft copolymer oil-displacing agent can improve the recovery factor of simulation crude oil by 11.3%. |
