Study of single well pressurization and water injection experiments in low permeability reservoirs
Daqing Oilfield Ninth Oil Production Plant Qijia Oil Production Operation Area, Daqing, China
In the process of water injection development in low-permeability and extra-low-permeability oil fields, the water absorption capacity of injection wells continues to decline, and the number of under-injection wells is increasing, which affects the development effect of oil fields. In this paper, we take X oilfield as an example and carry out single-well pressurized water injection tests to determine the range of reasonable injection pressure for pressurized water injection and the geological conditions suitable for pressurized water injection. Through this project research, the water absorption capacity of injection wells can be effectively improved, and the oilfield development effect is improved, which provides a new idea to solve the problem of water injection difficulties in low permeability oilfield.
Key words: pressurized water injection / dynamic change characteristics / development effect / reasonable water injection pressure
