The definition of phase permeability for oil and water in watered oil wells

R.A. Guliyev

In the article the method of phase permeability definition for oil and water according to watered wells field research data is considered. Herein the current parameters of formation and the fluids physical properties (oil and formation water) were investigated. The well-known dependence between well product watering and bottom-hole zone surface filtration was used. The analytical and graphic expression of this dependence, where the function is two-variable, i.e. one of the arguments is the phase permeability for the oil, and the other for the water is shown. These permeabilities together with the fluids viscosity compose nondimensional value the criterion, used in set task solution. In the suggested way the phase permeabilities are defined via the stepwise approximation.
