Abstract

See full text

The present disclosure provides a device for full-wave field seismic source based on a gas explosion technology and a method for acquiring seismic data. The device includes a cylindrical explosion-proof metal outer barrel, and four sides of the explosion-proof metal outer barrel are fixedly connected to four high-strength steel plates. The device also includes a cylindrical explosion-proof metal gas explosion inner barrel and pipelines for injecting high-pressure air and high-pressure gas into the gas explosion inner barrel. A center of the gas explosion inner barrel is installed with an electronic ignition gun, which is connected to a GPS timing module connected to the electronic ignition gun. The device further includes a controller configured to control a seismic source of a gas explosion full-wave field. Longitudinal wave source signals propagating vertically downward and perpendicular to ground, shear wave source signals propagating downward and parallel to a seismic source line direction, and shear wave source signals propagating downward and perpendicular to the seismic source line direction are triggered in sequence at each seismic source point. Longitudinal wave data and two transverse wave data orthogonal to each other and parallel to the ground excited through the each seismic source point are recorded in sequence by three-component geophones deployed on the ground, thereby achieving full-wave field exploration.
