PROCEDURE FOR INCREASE OF PERMEABILITY OF BOTTOMHOLE ZONE OF OIL-BEARING BED Russian patent published in 2011 - IPC E21B43/25 

FIELD: oil and gas production.

SUBSTANCE: there are preliminary determined geological-physical parameters of bottomhole zone of bed including pore-metric curvature of material of collector f(r). There are chosen optimal values of pulse duration, current density in pulse j, well pulses Q and total time of treatment t for successive pulse electric treatment of bottomhole zone. Bed pressure p₀ and bed temperature T₀ as additional thermo-baric characteristics of bottomhole zone are also determined. Duration of pulse τ is calculated by formula, density of current in pulse j by formula Also, porosity of pulse current is chosen within the range 1≤Q≤2, while total time of pulse electric treatment is set as not exceeding

EFFECT: upgraded accuracy of determination of parameters of pulse electric treatment for increase of absolute permeability of bottomhole zone of oil bearing bed.
