METHOD FOR VIBROSEISMIC TREATMENT OF HYDROCARBON DEPOSIT AND SYSTEM FOR REALIZATION OF SAID METHOD Russian patent published in 2004 - IPC

FIELD: seismology.

SUBSTANCE: method includes generation of longitudinal and transversal waves by means of vibroseismic oscillation sources. Said sources are placed on surface and/or in vertical, and/or in slanted, and/or in horizontal, and/or in branching wells. Then, vibroseismic treatment is performed on environment with hydrocarbon deposit by means of said generated longitudinal and transversal waves. Order of generation of transversal and longitudinal waves is controlled, or waves are generated concurrently. Also controlled is direction of longitudinal waves, by means of enabling respective vibroseismic oscillation sources and by polarity of transversal waves. System for realization of method has plurality of said sources, meant for placement on surface and/or in vertical, and/or in slanted, and/or in horizontal, and/or in branching wells. These are provided with means for generating oscillations, connected to computer by means of communication channels. Computer serves for controlling the order of generation of longitudinal and transversal waves, direction of longitudinal waves and polarity of transversal waves.

EFFECT: higher effectiveness of vibrotreatment of hydrocarbon deposits and of secondary oil extraction.
