Research and Test of Gas Explosion Source

The gas explosion source has the advantages of being safe, environmental protection, and suitable for use on complex surfaces. It is an important component of green seismic exploration sources. It also features adjustable parameters like initial explosion pressure, detonation wave velocity, and excitation energy, which create conditions for generating high-quality seismic waves in various rock formations. This paper introduces the basic working principles of the gas explosion source, cavity design based on numerical simulation, and some devices for gas explosion primary wave excitation. Some gas explosion excitation devices have been tested in the field for point and line verification, and preliminary results have been observed. The author believes that the consistency of the gas excitation source’s excitation time accuracy basically meets the requirements of the seismic exploration industry, and the gas explosion source has the potential to replace explosive excitation. The gas explosion source has more room for exploration and development in the future.
