针对目前石油地震勘探的瓶颈--检波器性能差的问题,设计了一种新型光纤Bragg光栅(FBG)地震检波器,阐述了其工作原理,并从理论上给出了检波器的响应函数等参数。由于FBG的传感优势,这种新型地震检波器动态范围可达94dB,灵敏度高,重量轻,造价低,是理想的新一代地震勘探信号采集单元。 In view of the current bottleneck of petroleum seismic exploration - the poor performance of the geophone, a novel fiber Bragg grating (FBG) geophone is designed, its working principle is described, and the response function of the geophone is given theoretically parameter. Due to the sensing advantages of the FBG, this new geophone has an excellent dynamic range of 94 dB, high sensitivity, light weight and low cost, making it ideal for a new generation of seismic exploration signal acquisition units.
