【摘要】 随着电子、计算机技术等相关技术的快速发展,物探采集仪器性能的日臻成熟和不断提高,地震数据采集前端的检波器技术的发展成为整个物探装备发展的瓶颈。本论文在结合九五国家863项目时移地震采集关键设备研制基础上对光纤拖缆检波器的研制进行了初步探讨。光纤检波器频带宽、灵敏度高、体积小、重量轻、不受电磁干扰等一系列优点,适合高精度石油勘探,油田精细开发,并将成为未来高性能检波器的发展方向。更多还原

【Abstract】 Along with the rapid development of electronic and computer techniques, the feature of geophysical acquisition apparatus has continuously improved and matured day by day, but the development of geophone technique that is front-end of seismic data acquisition becomes bottleneck of development of total geophysical equipments, on the basis of combining with the State 863 Project of Ninth Five-Year Plan: the development of key equipments of time-lapse seismic acquisition, the paper conducted preliminary discussion on the development of optical-fiber drag cable geophone. The optical-fiber geophone is characterized by broad band, high sensibility, small size, light weight and without interference of electro-magnetic waves, which is suitable for high-resolution oil exploration and fine development of oilfield and is developing direction of future high-property geophone.更多还原
