Estimating productivity factors of new wells of fields of Perm Krai North

Authors: V.V. Poplygin, D.V. Golovkov (Perm National Research Polytechnic University, RF, Perm)

Key words: oil deposit, productivity factor, bottom-hole pressure, reservoir pressure, deformations.

The results of operation of the new production wells of fields of Perm Region North are considered. It is shown, that productivity factors of new wells, which are brought into service after deposits pilot operation, significantly reduced. The main reasons of productivity factors reduction are deterioration of an objects energy state, reducing permeability and effective thicknesses in places of the new wells bringing into operation. The estimation of the degree of influence of degassing of the reservoir oil and changes of reservoir permeability due to its deformation in the area of bottom-hole pressures below the saturation pressure for Siberian field on the change of the actual wells productivity factors is separately executed.
