BRINGING ELECTROMAGNETIC EFFECTS ON WELL INNER SPACE AT PRODUCTION OF HYDROCARBON STOCK Russian patent published in 2014 - IPC E21B43/25 E21B28/00 

FIELD: oil-and-gas industry.

SUBSTANCE: invention can be used for increase in amount of pumped fluid, oil extraction factor, and decrease in sedimentation of natural hydrate and hydrate-hydrocarbon sediments on borehole equipment elements. Proposed method consists in incorporating the device with radiator and controlled electromagnetic wave field generator with electrically driven rotary pump downhole motor bed. Note here that irradiation of electromagnetic wave field is performed in resonance frequency of downhole space. Said frequency is defined during testing. Note here that testing is carried out at preset time intervals while during intervals between tests said generator is changed into downhole resonance frequency mode to allow the irradiator to generate standing electromagnetic waves along downhole space axis.

EFFECT: higher efficiency of extraction.
