Description

technical field [0001] The invention relates to an ultrasonic seismic physical simulation experiment for geophysical exploration. It can perform ultrasonic excitation and ultrasonic moving multi-point reception on the surface of a curved geological model, thereby performing ultrasonic imaging. It belongs to the field of non-destructive testing and testing, and particularly relates to a curved geological model An ultrasonic testing system and an ultrasonic acquisition method. Background technique [0002] Geophysical exploration is one of the most commonly used and most effective exploration methods for oil exploration, coal exploration, hydrological and engineering exploration. It uses explosions or other methods to generate sound waves, and embeds many geophones at a certain distance on the ground to receive seismic waves. After multiple records and post-data processing, seismic sections can be made. On the section, not only the ups and downs of the strata can be seen, but...

Problems solved by technology

The disadvantage is that there is an extra layer of water medium, which will cause part of the ultrasonic signal to be lost and diffused and the received signal strength is not enough, resulting in unclear internal information of the curved surface geological model and difficult to analyze
