| 摘 要： | 与陆上勘探的情况不同,海洋勘探面临着新的技术问题,包括：液相介质中大地电场信号的测取,在海底条件下实现采集装置的布放以及探测设备的水下运载,等。解决这些问题在于：研制用于海底测量的大地电场传感器;根据海洋作业特点开发专用的水下伸张测量臂;采用声控方式实现探测设备的沉放与上浮。海洋探测的初步成果表明,目前所实施的技术方案实用且可靠。

| Abstract: | Compared with land exploration,marine exploration is confronted with such technical challenges as acquiring geoelectrical signals in liquid environment,setting the prospecting device automatically in the ocean and picking the instrument up safely from the sea.Several solutions to these problems were working out,that is,geoelectrical field sensor and flexible measure arms which were suitable for marine environment and the acoustic control system which controls remotely the sink and float of the instrument.Primary marine prospecting experiments show that these solutions are effective and reliable. |
