摘要

摘要: 利用海洋自然电位法可以探测海底多金属硫化物矿体的位置和轮廓。在调查过程中，可以进行水平观测和垂直观测，本文对这两种观测方式的探测效果进行数值模拟分析，结果表明垂直观测异常大，对矿体的横向分辨率高。但在进行垂直观测时，电极离底低，工作风险大。所以在实际调查过程中，需要根据需求选择合适的观测方式。另外，在实际测量过程中，电极对会偏离垂直方向和水平方向，将导致异常结果发生变化，因此在数据资料处理与解释过程中要注意。本文可以为海底多金属硫化物自然电位调查提供参考。

Abstract: Using the marine self-potential method could explore the position and size of the seafloor hydrothermal polymetallic sulfide ore body. In the practical marine investigation, we could use the horizontal and vertical measurements. Here we used the numerical simulation method to analyze the detection effection of these two measuring ways. The analysis result indicates that vertical measurements could get a bigger anomaly than horizontal measurements. And the lateral resolution of vertical measurements is higher than horizontal. While vertical observation system's electrode is more close to the seafloor and have bigger operating risk than horizontal measurements. We need choose applicable detection system and observation way according to actual requirements. In the actual detection, there will be an angle between the electrodes and the horizontal direction. It will lead to a change of anomalies. We need to notice it in the data processing and interpretation. It can provide us with some reference about the marine exploration of the seafloor polymetallic sulfide.
