On fluid influx to imperfect wells due to penetration degree in multi-layer deposits with deformable reservoirs
G.I. JalalovThe article deals with the solution of problem of increase of well injection capacity by regulation of perforation density during fluid influx to imperfect wells due to penetration nature in multi-layer, heterogeneous deposits by penetration with deformable reservoirs. During problem solving it has been assumed that layer injectability, connected together only by wells, is expressed by the Dupuis formula and perforations density in high permeable layer constantly. A simple formula has been obtained for determination of the perforation density in the layers with poor permeability. In particular, the mathematical experiments have been conducted for dual-completed deposits according to initial data. The influence of the bedded reservoirs deformation on the number of perforation holes has been studied and established that under the same conditions their amount in the deformable reservoirs in more than in non-deformable.
