Determination of oil fields water flood conditions
The processes of water injection into wells are studied for different possible options of the formation bottomhole stimulation, to investigate a behaviour of the displacement front depending on the character of the displacing fluid action with creation of a vast water-oil zone of the mixed flow or a narrow zone better reflecting the conditions of the frontal drive, to define the time of the displacement front movement towards the development wells. The analysis is based on the numerical simulation of unsteady-state processes at liquid injection in the formation with a subsequent wells shut-in and efficiency recording.
