Linear one-dimensional filtration flow of incompressible viscous-plastic oil in inhomogeneous reservoir

S.G. Novruzova

The paper presents the results of task solution on stationary filtration plane-parallel flows from the stripe-like layers to the straight-line gallery. Differential equation of generalized Darcy law has been solved and hydrodynamic calculation formula of the main parameters characterizing the operation of straight-line gallery developed. While solving the differential equation of generalized Darcy law for the main parameters characterizing both parts of inhomogeneous formation, the calculation formulas of filtration rate, current pressure, productivity, current pressure gradient, as well as average permeability, average initial pressure gradient and total gallery recovery rate have been developed. Due to them, the exploration project of recently proven field with viscous-plastic oil should be developed, besides, they have to be used in the solution of various tasks of such fields’ development.
