METHOD FOR EXTRACTING OIL AND GAS DEPOSIT Russian patent published in 2005 - IPC

FIELD: oil and gas extractive industry.

SUBSTANCE: method includes pumping of replacing agent through force wells. Cyclic vibro-seismic treatment with alternating frequencies is performed on bed, using ground vibration sources. Composition and amount of extracted fluid is determined after and before treatment. Dominating frequencies of bed are detected on basis of reaction of micro-seismic noise thereof on vibro-seismic treatment. Additional vibro-seismic treatment is performed by signal being a total of at least two monochromatic signals with frequencies equal to dominating frequencies of block of productive oil deposit bed. Treatment is performed till development of cracks, while placing blocks in resonance oscillations, and separating of inner potential energy, providing for intensification of processes of forming of clusters in extensive zone from blocks of productive bed having different sizes.

EFFECT: higher oil yield.
