摘要
介绍了中国科学院地质与地球物理研究所自主研制的用于深水油气地球物理勘探的高频微功耗海底地震仪研制情况 .高频海底地震仪的仪器舱和水声释放器单球一体化总体结构设计 ,提高谐振频率和耦合频率 .采用先进的 32位单片机技术 ,系统具有体积小、重量轻、微功耗 (<30 0mW)和宽工作频带 (2～ 10 0Hz)的特点 .
The information of development of High Frequency OBS (Ocean Bottom Seismograph) is introduced. It is developing by Geology and Geophysics Institute of CAS for deeply water oil and gas geophysics exploration. Differing from other OBS, in the instrument,the seismograph and the sonar releaser is integrated into a sphere cabin. By this means the instrument's frequency of resonance and frequency of couple are improved obviously. The advance technique of 32-bit MCU is applied. It has some merits including miniature volume,light mass and micro power dissipation (<300 mW)and broad work frequency(2～100 Hz).
