PRODUCTION SIMULATION METHOD IN OIL WELLS AND DEVICE FOR ITS IMPLEMENTATION Russian patent published in 2014 - IPC E21B43/25 E21B43/24 E21B28/00 E21B36/00 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to the field of oil and gas industry, mainly to production of viscous and superviscous oil, and it may be used for production stimulation of oil with viscous components and deposits. High-frequency impulse current is generated by a group HF surge-current generators in a group of twin-transmission power lines in a group of wells and consisting of two isolated conductors or one isolated conductor and used as the second metal conductor of pipelines in the group of wells. The impact is made by an electromagnetic high-frequency pulsed field generated by high-frequency impulse current of conductors in the groups of twin-transmission power lines to the metal surface of pipelines in the group of wells. Thermal and acoustic impact is made on intratubal liquid in the well group and through it on the oil deposit by heating and mechanical vibration of the pipeline metal which occurs at passage of high-frequency impulse current through the twin-transmission power line. Additional thermal and acoustic impact is made on intratubal liquid in the well group and through it on the oil deposit by heating and pressure fluctuations which occur at the end of the twin-transmission power line in result of high-frequency impulse charge through intratubal liquid. At that the HF surge-current generators are set so that they generate high-frequency current pulses with identical pulse length and repetition.

EFFECT: increase of oil production stimulation.
