Abstract

In this paper we report the development and laboratory performance test of a high sensitivity 3C fiber laser geophone for borehole seismic acquisition application. First we are presenting the development of the fiber laser geophone and then testing its performance in third-party testing laboratory. The performances of the fiber laser geophone such as sensitivity, micro-seismic response, noise and temperature resistance are tested. Its performance is compared with high-temperature coil geophone simultaneously. The fiber laser geophone has advantages of wider bandwidth, better low-frequency and high-frequency micro-seismic response. These advantages are crucial for downhole micro-seismic monitoring geophysical imaging and micro-seismic monitoring.
