Abstract

The device applies spread spectrum data station, earthquake prospection wave detector with three-conponent digit, data collecting station set between abovesaid station and detector. The connections for signal are follows. The data output line of the data collecting station is connected to data input line of the spread spectrum data station. The data is transmitted to recording centre via the spread spectrum data station as per time sequence after the data of detector is buffer-stored by the data collecting station so that the system can send 3000 route earthquake data collected from 176 data collecting station to the recording centre by only occupying one radio channel.

Description

Technical field: [0001] The invention relates to a seismic prospecting device, in particular to a device for transmitting signals of geophones distributed at several points to a recording center during the seismic prospecting process. Background technique: [0002] Seismic prospecting is still the main method for oil and gas exploration on land and sea. The basic method is to bury thousands or even tens of thousands of seismic wave sensors (ie, geophones) on the ground of the exploration target area, and to drag and drop several 1-2 km long offshore floating cables ( Floating cables wrap a seismometer every tens of meters), and then use explosives (on land) or high-pressure air guns (on sea) to stimulate artificial earthquakes. Seismic waves propagate deep underground, and when they meet the interface of strata of different properties, they will be reflected. The geophone picks up the reflected waves and converts them into analog electrical signals, and then converts them i...
