FIELD: physics; geophysics.SUBSTANCE: invention relates to geophysics and can be used for offshore seismoacoustic survey of oil and gas deposits. Disclosed is a small-scale self-contained seismoacoustic station, comprising an equipment carrier which is mounted at the seabed and emerges after releasing the ballast. The equipment carrier includes, arranged in a sealed spherical container, an on-board computing unit, a power supply, a three-component geophone and, installed outside the sealed container, a hydrophone, a hydroacoustic communication receiver and a device for positioning and removing the equipment carrier from the ground. The equipment carrier also includes means of searching for an emerging equipment carrier, which is in the form of a flash beacon, a Glonass satellite navigation system, a Gonets low-orbit satellite communication system and an active radar reflector. The recording circuit consists of a four-channel filtration and amplification unit. Signals from the hydrophone and seismic detectors are used to form an array for separate sampling with a length of sixteen-bit layers, which are transmitted to corresponding information storage channels, representing solid-state memory consisting of 4 flash cards of 2 GB each.EFFECT: providing more reliable areal survey data.5 dwg |
