Plugging Mechanism Research on LD10-1 Oilfield

Polymer flooding has turned into the important technology for enhancing the recovery ratio in LD10-1oilfield. 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 rom the adsorption of polymer,etal ons and reservoir permeability.
