Seismic noise imaging exploration method and apparatus, and a storage medium

Abstract

The embodiment of the invention discloses a seismic noise imaging exploration method and apparatus, and a storage medium. The method that is applied to an exploration system including a plurality of three-component low-frequency detectors that are arranged on one straight line at a preset interval comprises: acquiring a plurality of low-frequency three-component data including first data and two horizontal components and second data of a vertical component by the plurality of three-component low-frequency detectors; acquiring a measurement dispersion curve characterizing a correspondence relationship between a surface wave phase velocity and a frequency by using the plurality of the second data; acquiring a plurality of velocity models characterizing a correspondence relationship between the depth and velocity of the stratum of each measuring point according to the measurement dispersion curve and the plurality of low-frequency three-component data; and on the basis of the plurality ofvelocity models, determining a stratum velocity profile of the testing area based on the plurality of velocity models.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to a seismic noise imaging exploration method, device and storage medium. Background technique [0002] At present, the method of seismology using the actual observation of surface fretting noise imaging is mostly used in the study of deep structures, and the use of fretting noise is used in shallow engineering exploration such as the refraction fretting method, but this method can only obtain one in a long array. Velocity model with poor lateral resolution. However, there is currently no effective solution to this problem. Contents of the invention [0003] In view of this, the embodiments of the present invention expect to provide a seismic noise imaging exploration method, device and storage medium. [0004] The technical embodiment of the embodiment of the present invention is realized like this: [0005] An embodiment of the present invention provides a seismic...
