Micro-motion technology exploration method and device and storage medium

Abstract

The embodiment of the invention discloses a micro-motion technology exploration method and device and a storage medium, and the method is applied to an exploration system comprising a plurality of single-component low-frequency detectors. The plurality of single-component low-frequency detectors are arranged on the same straight line at preset intervals; the method comprises the following steps: obtaining single-component low-frequency micro-motion data of a plurality of exploration points through the plurality of single-component low-frequency detectors; determining a correlation curve corresponding to the first exploration point based on the single-component low-frequency micro-motion data of the plurality of exploration points, wherein the correlation curve is used for measuring the similarity between the single-component low-frequency micro-motion data corresponding to the first exploration point and the single-component low-frequency micro-motion data corresponding to other exploration points; obtaining a speed model related to the first exploration point according to the correlation curve, wherein the speed model represents the corresponding relation between the stratum depthand the surface wave speed related to the first exploration point; determining a stratum velocity profile of the exploration area based on the speed model, wherein the exploration area comprises areas corresponding to a plurality of exploration points.

Description

technical field [0001] The invention relates to the technical field of seismic exploration, in particular to an exploration method, device and storage medium of micro-motion technology. Background technique [0002] The micro-motion array technology can be divided into different device types. Commonly used device types include "linear arrangement type", "embedded triangle type", "concentric circle type", "cross type" and "L type", etc. Different device types The types have the following characteristics: [0003] 1) Different device types have different site requirements [0004] Among the existing device types, the linear arrangement type is more convenient in the implementation process and has the highest operating efficiency, while other types of devices require specific spatial combination relationships, and it is difficult to fully satisfy the device layout during the implementation process, especially in the urban implementation process. requirements, to some extent l...

AI Technical Summary

Problems solved by technology

[0007] Therefore, in the actual application of the micro-motion table array method, there are problems of limited facts or high speed, and the two cannot be solved at the same time, and the "contradiction between space and speed", which seriously limits the application of this method

[0008] In addition, the active source surface wave prospecting method needs artificial excitation of the seismic source during the implementation process, which cannot be implemented i
