FIELD: geophysics.
SUBSTANCE: invention relates to the field of geophysics and is intended for measuring three components of the medium vibration vector caused by the movement of oil, gas, water, fracturing and other causes. Device is also designed to determine the direction of the plane of finding sources of geoacoustic signals. Claimed device comprises three mutually orthogonal sensors of geoacoustic signals, first, second and third switches, an analog-to-digital converter, transmission unit, three gravitational transducers, three amplifiers with high input impedance and input voltage compensator, two temperature sensors, a band-pass filter unit, control unit and power supply, calibration harmonics generator.
EFFECT: increased accuracy and informativeness of research.
