AUTONOMOUS SEISMO-ACOUSTIC STATION Russian patent published in 2018 - IPC G01V1/38 

FIELD: geophysics.

SUBSTANCE: invention relates to geophysics and can be used for seismo-acoustic studies on the shelf while carrying exploration work for oil and gas deposits. Autonomous seismo-acoustic station (ASAS) is proposed, containing a carrier of equipment (CE), installed on the seabed, CE includes an onboard computer unit (OCU), power source, three-component pickup, as well as a hydrophone installed on the outside of the sealed container, the device for setting and removing the CE from the ground, means for searching for a floating CE, made in the form of a flashing light, a Glonass-type satellite navigation system, low-orbit satellite communication system of a type "Gonets" and active radar reflector, breaker, duplicated by commands from the urgency device, from the seal sensor, from the pressure sensor, recording path consisting of a four-channel filtering and amplifying unit that provides filtering of signals from the outputs of three-component pickups and a hydrophone in the 5-200 Hz frequency band and amplification of signals for their input to the input of the four-channel analog-digital converter unit, output signals from which are separately fed to the input channels of the former, where from the signals of the hydrophone and pickups an array of a single sample is formed with a length of sixteen-digit words fed from the output of the former to the corresponding channels of the information storage device, which is a solid-state memory of 4 flash cards with a capacity of 2 GB each, wherein the analog-digital converter unit consists of four 14-bit ADCs in which the apparatus carrier body is made of stressed reinforced concrete and has a surface part, on which a system of collecting and transferring ashore information from the measuring systems located at the seismic station is located. In this case, the carrier of the equipment is made in the form of separate annular monolithic sections, of stressed reinforced concrete and equipped with a guide (locks),

Inside the annular monolithic sections there are guide tubes for placing steel cables or rods in them for preliminary compression of a buoy body, jacks are placed in the lower part of the buoy, electric drive and strain gauges are placed in the buoy body.

EFFECT: technical result is more reliable seismic data.
