Abstract

The invention discloses a detection depth determination method and device, equipment and a storage medium. The method comprises the steps that detection signals received by at least two wave detectorsare obtained, and the detection signals are generated by refracting and reflecting seismic waves emitted by seismic radar on the basis of underground media; according to set time duration, each detection signal is segmented so as to generate multiple sub detection signals; similarity parameters between each sub detection signal and other detection signals in the same sampling section are calculated, and the detection depth of the seismic radar is determined on the basis of the similarity parameters. According to the technical scheme, the determination process of the seismic radar detection depth can be simplified, required time for determining the seismic radar detection depth is shortened, consumed manpower and material resources for determining the seismic radar detection depth are reduced, the efficiency of determining the seismic radar detection depth is improved, and the application range of the seismic radar detection depth determination method is increased.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a method, device, equipment and storage medium for determining a detection depth. Background technique [0002] In recent years, with the increasing demand for oil and gas use, seismic exploration for exploring the properties and morphology of subsurface rock formations has also received more and more attention. [0003] The essence of seismic exploration is to use artificial seismic sources (explosives, seismic source vehicles or high-speed rail, etc.) The characteristic signal of the domain), broaden the frequency band, improve the resolution, etc., to determine the response of the underground medium to the artificially excited seismic wave, so as to infer the nature and shape of the underground rock formation. Based on this principle, prospectors can actively launch seismic waves underground through the developed ground-penetrating radar, actively explore the stru...
