摘　　要：详细介绍了针对我国天然气水合物勘探需求研制的50k J大能量等离子体震源。该震源结构采用集约型设计,所有设备均集成于一个可移动集装箱实验室内,方便设备运输与使用。海试研究表明,该震源最大地层穿透深度超过1000m。与传统的震源相比,等离子体震源具有更高的地层分辨率,提高了天然气水合物地球物理识别的可靠性。大能量等离子体震源系统的研制成功,打破了国际垄断,对我国海洋工程、海洋地学研究甚至国防均有较大意义。The development of plasma seismic source with large energy output of50kJ for gas hydrate exploration in China was introduced in this paper.The structure of the source was compactly designed,and devices were integrated in a mobile laboratory in containers for convenient transport and operation.The field test results showed that the maximum penetration depth of strata of the source was over1000m.Compared with the traditional source,the plasma seismic source had higher stratigraphic resolution and improved the reliability of geophysical recognition of gas hydrate.The successful development of the50kJ plasma seismic source system broke the international monopoly by whom,and has great significance for China's marine engineering,marine science research and national defense.
