Description

Seismic detection device and its system

technical field

The utility model relates to the technical field of geological exploration, in particular to a seismic detection device and a system thereof.

Background technique

The data acquisition of the seismic detection device is the key in the process of seismic exploration; the traditional seismic acquisition equipment includes: seismograph, power supply, cable, measuring tape, and geophone. During the construction process of seismic data acquisition, it is necessary to accurately measure the position of each geophone according to the designed observation system, and then connect each geophone in series through a cable to the seismic recorder to complete data transmission and storage. Every time the geophone moves, it needs to measure the position and disassemble and transport the cables, which undoubtedly increases a lot of workload and labor costs, and also reduces the collection efficiency of track spacing data. Among them, the track spacing refers to the lateral distance between two geophones at the same horizontal interface.

With the development of seismic exploration technology and the improvement of exploration accuracy requirements, the accuracy of seismic data acquisition has become particularly important. Most of the existing geophone devices only have the function of data acquisition; when the surface is rough, measuring tools such as a tape measure are used to measure and determine the position of the geophone. Usually, the distance between two geophones on the ground surface is measured, which cannot be accurately measured. The actual distance of the geophone affects the trace spacing of data acquisition, affects the quality of the collected trace spacing data, and reduces the accuracy of seismic exploration. In addition, the existing geophones need cables for data transmission, which increases a lot of cost and the workload caused by receiving and releasing cables.
