FIELD: oil production industry. SUBSTANCE: this method particularly relates to control of displacement of water-oil contact through oil bed. Control for displacement of water-oil contact through oil bed is achieved through changing of amplitude-frequency characteristics of seismic background in infrasound frequency range. Used for this purpose are three-component seismic receivers located above deposit. Shifting of water-oil contact in oil bed below control point is manifested by reduced amplitude of amplitude- frequency characteristic. Recording is effected during 40-60 min. In process of Recording, additionally generated are oscillations in infrasound range of frequency. Aforesaid method helps in developing express-methodic for determining position of water-oil contact line without drilling auxiliary bore-holes. EFFECT: higher efficiency. 6 cl, 2 dwg
