Paper Abstract

In this paper a new type of fiber Bragg grating (FBG) sensor based geophone is introduced. This FBG geophone is mainly used in the seismic reflection survey of oilfield exploration to detect the motion of the earth. The basic detection principle of the seismic survey and the fiber Bragg grating sensing technique is explained in brief. An eight channel FBG sensor based geophone system is developed and demonstrated in both laboratory tests and field tests. The experimental results show the sensor system frequency response bandwidth at 10-100Hz in shallow layer and 10-140Hz in medium and deep layer separately. A high dynamic range and good signal to noise ratio are also observed in the experiment.
