DEVICE FOR THERMAL PROCESSING OF HYDRATED GAS ACCUMULATION Russian patent published in 2014 - IPC E21B36/04 E21B43/24 

FIELD: mining.

SUBSTANCE: invention relates to mining and can be used for development of hydrated gas accumulations, heat treatment of well working area and recovery of hydraulic connection between bed and well. Proposed device comprises two heater cases, water feed system including two discharge valve arranged in second case. Additionally this device comprises oil-well tubing (OWT) connected with water feed pipe with pump and water tank, heat-resistance packer arranged above said cases, voltage regulator and distributor with OWT joint assembly arranged along its axis. Said distributor has tubular dielectric inserts and adapter with bore aligned with tubular insert bore. Note here that conductor top section is connected with power cable cores via adapter. Second case incorporates discharge valves arranged in its top section and is filled with working fluid and arranged outside said first sealed case. Said first case accommodates perforated electrode discs while central tubular conductor incorporates zero electrodes fitted in electrode gaps outside said heat-resistant insulators. Electrode discs are rigidly coupled with central conductor and isolated by heat-resistant insulators fro heater first case filled with conducting fluid. Said first case has extra pressure and level gages, emergency pressure valve and bottom bushings. Note here that heat-resistant packer is arranged between distributor and second case while OWT is connected with first case via second case.

EFFECT: higher intensity of thermal processing, expanded operating performances.
