Micro-motion exploration method and device and electronic equipment

Abstract

The invention provides a micro-motion exploration method and device and electronic equipment, and relates to the technical field of geological exploration. The method comprises the steps: collecting original micro-motion data of a target survey line based on a pre-arranged micro-motion observation device; enabling the micro-motion observation device to distribute wave detectors according to a preset channel interval, wherein the number of arranged collection channels is far larger than the basic number of channels of a single measuring point, and the basic number of channels is the number of channels meeting a preset detection depth requirement; on the basis of the basic channel number, determining micro-motion data of a plurality of continuous measuring points from the original micro-motion data, and acquiring micro-motion data corresponding to each measuring point in the plurality of continuous measuring points; and according to the micro-motion data corresponding to each measuring point in the plurality of continuous measuring points, determining a geological exploration result of an interval where the plurality of continuous measuring points are located. According to the embodiment of the invention, the wave detectors are arranged in a manner of unconventional channel number, and the micro-motion data of a plurality of continuous measuring points are acquired at one time, so that the micro-motion exploration efficiency can be improved, the transverse resolution of the underground stratum is improved, and the accuracy of the exploration result is improved.

Description

technical field [0001] The invention relates to the technical field of geological exploration, in particular to a micro-motion exploration method, device and electronic equipment. Background technique [0002] At present, safety problems such as urban ground subsidence and dam failure occur frequently, threatening the safety of human life and property. There is an urgent need for a method of geological detection in places with many interference factors such as cities. In the existing exploration technology, the detection depth of geological radar is relatively shallow, which cannot meet the depth requirements; electrical exploration is difficult to arrange electrodes on urban roads and cannot be implemented. However, micro-motion exploration is subject to little external interference, does not require artificial source excitation, and has a large sounding, which can meet the needs of urban geological surveys.

Problems solved by technology

[0003] In the past, when the micro-motion exploration technology was used for data acquisition, the micro-motion data of one exploration point could only be collected once the array was deployed. Acquisition, this exploration method is heavy and time-consuming, and the exploration efficiency is low; in addition, because the acquisition time of different exploration points on the same profile is sequential, the micro-motion data collected at different times may come from different seismic sources, and It may be affected by different interference sources, which increases the difference in the background field between the micro-motion data collected at different exploration points of the same exploration profile, which reduces the lateral resolution of the subsurface strata obtained from the inversion of the profile data, and also reduces the exploration efficiency. accuracy of results
