| Abstract: | In this paper, a field test on water plugging and profile control by a HPAM/Phenolic Aldehyde crosslinked polymer solution (LPS) used in the fault block reservoir with higher water content in Zhenw oilfield has been introduced. Results show that certain concentration of LPS can modify the vertical water injection profile, and makes the afterward water into the higher oil content layer, and improves the injection pressure of water injection well. At the same time, the injection of LPS will changes the direction of liquid flow to adjust the profile in the high permeability formation. It can improve oil displacement efficiency and enhance oil recovery in the fault block with high water content. |
