Description

technical field [0001] The invention relates to an intelligent control compound coherent electric spark seismic source device for marine engineering geology. Background technique [0002] Marine seismic detection sources include air gun, water gun, sparker, and transducer. At present, the EDM sources commonly used in China include the SIG series produced by S.I.G in France and the Geo-Spark series developed by Geo-Resources in the Netherlands. In marine engineering seismic exploration, the EDM source is the most commonly used source. By changing the emission energy of the EDM source, seismic sections with different penetration depths and corresponding resolutions can be obtained. The EDM seismic source has been widely used in marine seismic exploration due to its wide spectrum range, high resolution, and ease of use. [0003] Due to the low frequency of the high-energy seismic signal, the formation penetration ability is strong, but the resolution is low, while the low-ene...
