Title:
FULL-WAVE-FIELD SEISMIC SOURCE APPARATUS BASED ON GAS EXPLOSION TECHNOLOGY, AND SEISMIC SOURCE DATA ACQUISITION METHOD
Document Type and Number:
WIPO Patent Application WO/2023/103221
Kind Code:
A1
Abstract:
The present invention provides a full-wave-field seismic source apparatus based on a gas explosion technology, and a seismic source data acquisition method. The full-wave-field seismic source apparatus comprises: a cylindrical explosion-proof metal outer barrel, wherein four high-strength steel plates are connected and fixed to the four sides of the explosion-proof metal outer barrel; a cylindrical explosion-proof metal gas explosion inner barrel; pipelines for injecting high-pressure air and high-pressure gas into the gas explosion inner barrel; an electronic ignition gun, placed at the center of the gas explosion inner barrel; a GPS time service timing module, connected to the electronic ignition gun; and a controller for controlling a gas explosion full-wave-field seismic source. According to the present invention, a longitudinal wave seismic source signal that is perpendicular to the ground and vertically downwards propagated, a shear transverse wave seismic source signal that is parallel to the direction of a seismic source line and downwards propagated, and a shear transverse wave seismic source signal that is perpendicular to the direction of the seismic source line and downwards propagated are sequentially excited at each seismic source point, and a three-component geophone arranged on the ground can sequentially record longitudinal wave data that is excited by the full-wave-field seismic source apparatus and perpendicular to the ground, and two pieces of transverse wave data that is excited by the full-wave-field seismic source apparatus, and is orthogonal to each other and parallel to the ground, and thus, full-wave-field exploration is truly realized.
