METHOD OF INCREASING WELL PRODUCTIVITY IN RECOVERY OF HYDROCARBONS Russian patent published in 2002 - IPC

Abstract RU 2191887 C2

FIELD: recovery of minerals, particularly, hydrocarbons; applicable for intensification of hydrocarbons inflow. SUBSTANCE: method includes preliminary determination of optimal frequency of pulse dynamic electromagnetic field of formation stimulation from ground surface by measurement at least by one registering device of predominant frequency of natural vibrations in infrafrequency range of hydrocarbon pool. Set up by downhole electrode in zone of producing formation is pulse dynamic electromagnetic field with preset pulse repetition frequency. Said treatment of producing formation is effected simultaneously with recovery of hydrocarbons. Energy of treatment is varied until maximum effect of increase of hydrocarbon inflow is attained. EFFECT: higher efficiency. 5 cl, 1 dwg
