Abstract

Abstract:

The development of plasma seismic source with large energy output of 50 kJ 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 over 1000 m. 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 the 50 kJ 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.

Key words: gas hydrate, large energy, plasma seismic source
