摘要
为解决海底压电检波器的二次定位问题 ,胜利物探公司于 2 0 0 0年引进了美国I/O公司声波测距定位系统(DigipointAcousticRangingSystem)。该系统是利用声纳测距来测定系统与压电检波器之间的距离并通过与系统连接的GPS系统最终确定压电检波器的实际位置。文章介绍了该系统的构成、定位原理及近几年多个滩海工区的应用效果 ,总结了该系统在浅海地震采集应用的经验 ,以供同行参考。
To position hydrophone in the seabed,Shengli Geophysical Corp.imported digipoint acoustic ranging system from I/O Inc.. This system positions actual hydrophone based on acoustic ranging principle. The paper introduces modules of the system,position setting principle and application result in shallow sea area recently,and summarizes experience about seismic acquisition in shallow sea by the system,only to apply craft brother reference.
