Study on the Combination of Multilayer Piezoelectric Seismometer
The key problem on seismic exploration is how to improve accuracy and resolution,A kind of multilayer piezoelectricity acceleration geophone is studied and discussed.carried on its amplitude frequency,phase-frequency characteristic theoretically,obtained the primary factor of the influence on frequency response,and improved in the piezoelectric crystal choice and geophone structure.The theory and the field test result indicated that,this piezoelectricity acceleration geophone has advantages over conventional geophones in frequency spectrum,resolution and high-frequency response,it is one better detection method,and the upgrade product of traditional geophone.
