METHOD OF INCREASING PRODUCING ABILITY OF WELL Russian patent published in 2009 - IPC E21B43/24 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to methods of increasing producing ability of well due to thermal effect onto payout bed at bottomhole zone of wells. According to the method thermal effect onto oil bed is performed by means of plasma obtained by electric arc decomposition of water into hydrogen and oxygen with their successive combination in a heat carrier. Periodical increase and decrease of plasma temperature is performed under the step law of rectangular form with initiation of heat waves in the payout bed, with increase and decrease of oil volume owing to heating and cooling and owing to its increased mobility in pores of the payout bed. Also periods of plasma heating are maintained uniform between them with duration not less, than an hour. At the same time cooling periods are also maintained uniform between them and with duration not less, than an hour.

EFFECT: increased efficiency of fluid extraction by payout bed at thermal effect.
