| 摘 要： | 海洋可控源电磁法（Marine Controlled Source ElectroMagnetic，MCSEM）是探测海底石油、天然气储层等矿产资源的一种新兴的海洋地球物理勘探方法。由于海洋环境复杂，电磁信号极易受到各种噪声的干扰，影响反演和解释效果。首先介绍MCSEM方法的原理及关键的数据预处理方法，然后总结了目前常见的随机噪声、空气波噪声和海水扰动噪声压制方法；最后分析了MCSEM数据去噪的发展方向。

| Abstract: | The marine controlled source electromagnetic (MCSEM) method is an emerging marine geophy-sical exploration method for detecting mineral resources such as submarine oil and natural gas reservoirs.In the complex marine environment,signals are very susceptible to interferences from various noises,which affects data inversion and interpretation.This paper first introduces the principle of MCSEM and key data preprocessing methods,then summarizes the methods for suppressing random noise,‘air wave’ noise and seafloor currents,and finally analyzes the future direction on how to denoise MCSEM data. |

| Keywords: | marine controlled source electromagnetic method random noise air wave noise the noise of seafloor currents noise suppression |
