METHOD OF IMPULSE TREATMENT OF PRODUCTIVE FORMATION AT EXTRACTION OF HYDROCARBON RAW MATERIAL AND CONTROL SYSTEM, WHICH CARRIES OUT Russian patent published in 2019 - IPC E21B28/00 E21B43/26 

FIELD: mining.

SUBSTANCE: group of inventions relates to mining and can be used for impulse treatment of productive formation. Proposed method comprises generation of disturbing dual electrohydraulic pressure pulses with time delay between said pulses in well bore at level of productive stratum. Value of delay is determined a priori by known model, and pulse pairs repetition frequency and their number are set proceeding from optimal dominant frequencies of oscillations of geoblocks determined based on known knowledge and / or empirical data. After the processing process is completed, its efficiency is determined during the process of approbation by the level of fluid influx and / or its gradient, composition of the well fluid, and if necessary, the process is repeated by changing the parameters of disturbing pressure pulses until achieving the optimum result. Also disclosed is a pulse processing control system.

EFFECT: technical result consists in improvement of efficiency of extraction of hydrocarbon material in low-yield deposits and deposits with hard-to-recover reserves.
