METHOD OF INCREASE OF PERMEABILITY OF OIL-BEARING FORMATION BOTTOMHOLE ZONE Russian patent published in 2003 - IPC

FIELD: oil and gas producing industry. SUBSTANCE: geological-physical parameters of formation bottomhole zone are determined by determination of porometric curve of reservoir material in bottomhole zone f(r) for computation of average value of radius r_aver of pore channels. Then, pulse duration τ and corresponding minimal permissible current density in pulse j are determined. Relative pulse duration is set within 1-3. Time for performance of pulse treatment is selected by respective formula. EFFECT: higher accuracy of determination of parameters of pulse electric treatment for efficient increase of permeability of oil-bearing formation bottomhole zone with reduced power consumption.
