| titleOfInvention | Xanthan gum graft copolymer oil displacement agent as well as preparation method and application thereof |
| abstract | The invention provides a xanthan gum graft copolymer oil displacement agent as well as a preparation method and application thereof. Based on molecular design, at least two of acrylamide (AM), 2-acrylamido-2-methylpropane sulfonic acid (AMPS), N-vinylpyrrolidone (NVP) and N,N-dimethylacrylamide (DMAM) are graft-copolymerized to xanthan gum macromolecules. Since the copolymerized side chain is introduced, the viscoelasticity, heat resistance and biological stability of the xanthan gum macromolecules can be greatly enhanced; the xanthan gum graft copolymer can be used as an oil displacement agent for tertiary oil recovery simultaneously; and the solution rate of the xanthan gum graft copolymer is obviously increased, and the xanthan gum graft copolymer can not easily generate gel in brine. When the xanthan gum graft copolymer oil displacement agent is used in a high-temperature high-salinity oil reservoir, the oil displacement effect is enhanced. |
