Study of single well pressurization and water injection experiments in low permeability reservoirs

In the process of water injection development in low-permeability and extra-low-permeability oil fields, absorption capacity wells continues to decline, number under-injection is increasing, which affects effect fields. this paper, we take X oilfield as an example carry out single-well pressurized tests determine range reasonable pressure for geological conditions suitable injection. Through project research, can be effectively improved, provides a new idea solve problem difficulties low permeability oilfield.
