| Abstract: | Ertao unit in Region 6 of Gudong Oilfield has been in high water-cut stage with low water displacement efficiency. Cost of water injection is reduced and oil displacement efficiency is improved by converting water drive to expansion drive. Thus an experiment is conducted for converting displacement mode and the principle of expansion drive, principle of pressure transmission of the expansion drive as production remains constant and methods for calculating water drive production pressure difference are denoted. Expected result is achieved in field test. |
