摘要
利用水下电场传感器进行海洋大地电磁勘探时,水下电场测试的准确性和可靠性直接影响最终的勘探结果。水下电场传感器校准工作是在试验水池中进行的,评价该工作性能的关键技术指标有:试验水池中激发的水下电场的均匀性,水下电场均匀区的大小,系统供电电极激励源(电压或电流)注入位置以及数量等关键参数对水下电场均匀性的影响,不同的板状电极电导率与试验水池溶液电导率对水下电场均匀性的影响。这些工作目前在中国还是空白,试验结果证明可有效地解决上述技术难题。
When underwater electric field sensors are used to probe marine magnetotelluric,the accuracy and reliability of its tests directly affect final exploration results.Underwater electric field sensor calibration is carried out in the test pool.The key technical indicators to evaluate the performance are:the uniformity of the underwater electric field activated in the test pool,the size of its uniform area,influence on uniformity by the number of sources and its positions excited by the system power electrode(voltage or current),influence on uniformity by the conductivity of different plate electrode and the test solution.Our tests provide effective solutions to these technical problems.
