НЕФТЯНАЯ ПРОВИНЦИЯ

Abstract

​

​On the example of a high-viscosity oil deposit of the Bashkirian stage of the field in the Melekesskaya depression, an assessment was made of the influence of filtration channels on the production capabilities of wells. The methodological approach adopted in the analysis made it possible to come to the conclusion: 1) about insufficient density of perforation holes during the secondary opening of the carbonate productive horizon; 2) under conditions of saturation of reservoir rocks with high-viscosity oil, the depth of penetration of perforation holes begins to play a less significant role; 3) on the availability of a reserve of production opportunities to increase the productivity of wells.

Key words:

​

Carbonate reservoir, high-viscosity oil, Bashkirian stage, Melekesskaya depression, secondary exposure, low-productive reservoir, perforation, filtration channel, optimization of perforation density, methodical approach
