摘　　要：海洋电磁探测是利用海底介质的电磁感应信息,对海底的矿产资源分布进行电性推断的一种技术。由于天然气水合物与海底沉积物的电学性质差异,因此可以利用电磁探测方法用于探测海底天然气水合物。"863项目""天然气水合物的海底电磁探测技术",成功研制出我国的海洋天然气水合物电磁探测仪器。本文对海洋电磁探测原理、研究现状及我国"863项目"研制的海洋天然气水合物电磁探测仪器进行了介绍。Marine electromagnetic detection technology uses the electromagnetic induction information of seabed medium to infer the distribution of mineral resources by the difference of the electrical properties.Because of the differences between natural gas hydrate and sediments in electrical properties,we can use the electromagnetic detection methods to detect submarine natural gas hydrates.The national 863 project ＂Electromagnetic detection of submarine gas hydrate technology＂,which has successfully developed China＇s marine natural gas hydrate electromagnetic detection equipment.This paper introduced the principle of marine electromagnetic detection,developmental status and the electromagnetic detection equipment of marine natural gas hydrate,which is developed by the national 863 project.
