| Abstract: | Polymer flooding has turned into the important technology for enhancing the recovery ratio in LD 10-1 oilfield. Along with the application of polymer flooding, the blocking of polymer injection well is increasingly prominent, which influences the effect of polymer flooding and the regular production of oilfields. The author analyzed the blockage component by means of IR spectrum, XRD, XRF, ICP techniques, and researched the plugging mechanism of polymer injection from the adsorption of polymer, metal ions and reservoir permeability. |
