Product Description

4.5 Hz 10Hz 20Hz 40Hz 100Hz Geophones String In Seismic Surveys for Gas and Oil Exploration
 

 

I. Description of Geophones String In Seismic Surveys for Gas and Oil Exploration

 

Digital Seismic Sensors (Geophone) are available frequencies from 1Hz to 100Hz vertical and horizontal direction, and geophone-consisted three-component geophones, borehole geophone, tomographic imaging geophone series with stable performance, high fidelity and consistent quality in oil, gas exploration and other fields.

 

II. Applications and Features of Geophones String In Seismic Surveys for Gas and Oil Exploration

 

· 1~3Hz geophones applied for deep seismic prospecting, natural earthquake surveillance and prediction, pulse and microseismic measurement for bridge and highways, etc.

· 4~100 Hz widely used to seismic prospecting of petroleum, coal, metallurgy, defense engineering and etc.

· High sensitivity, low-distortion, reasonable damping coefficient, good linear response, good parameter conformity, higher resolution and excellent waterproof property.

· Small-sized, easy to install, easy to operate, large ambient temperature range, can meet the demand of multi-wave component seismic data acquisition technology
