GRAVITATIONAL-MAGNETIC-SEISMIC SYSTEM (VERSIONS)

FIELD: physics; geophysics.SUBSTANCE: group of inventions relates to geophysics and can be used in field studies for different purposes. Each of the systems includes gravitational acceleration sensors (1-1 - 1-3) on three components, magnetic field sensors (2-1 - 2-3) on three components, ground seismic vibration sensors (3-1 - 3-3) on three components, a unit (15) for determining coordinates of the system and accurate time, and a control, processing and recording unit (11) connected to all said devices. The control, processing and recording unit (11) has a function for measuring gravitational acceleration parameters and magnetic field parameters synchronously with measurement of seismic vibration parameters. The gravitational acceleration sensors (1-1 - 1-3), magnetic field sensors (2-1 - 2-3) and ground seismic vibration sensors (3-1 - 3-3) are placed in a sensor unit (4), which also includes a temperature sensor (21). All sensors in the sensor unit (4), except the temperature sensor (21) are placed in a space whose geometric parameters are comparable with the sum of geometric dimensions of said sensors. In one version, the system includes a controllable heater (22) which maintains temperature in the sensor unit (4) using a signal coming from the temperature sensor (21). In another version, the temperature sensor (21) is connected to the control, processing and recording unit (11), which has a function for correcting measured parameters according to temperature changes in the sensor unit (4).EFFECT: high accuracy of determining physical characteristics of investigated rock in a measurement space, smaller dimensions of the systems.12 cl, 4 dwg Группа изобретений относится к области геофизики и может быть использована при разноцелевых полевых исследованиях.
