Seismic Sensor Geophones String Land Geophone String
Land geophone string is a series of geophones, which are devices used for detecting ground vibrations, arranged in a linear configuration and used for seismic data acquisition on land. The geophones are typically connected by cables and placed in shallow holes or on the surface of the ground, where they can detect seismic waves generated by energy sources such as explosives or vibrating trucks.
The geophone string is used to record the arrival times and amplitudes of seismic waves, which are then analyzed to create an image of the subsurface geology. This image can be used for various applications, including oil and gas exploration, mineral exploration, and environmental studies.
Land geophone strings can vary in length depending on the desired resolution and depth of investigation. Shorter strings are used for high-resolution surveys, while longer strings are used for deeper exploration. The spacing between geophones can also be adjusted to optimize the data quality and resolution.
