Abstract
The present invention belongs to the field of geophysical exploration, and discloses physical seismic simulation test apparatus and method based on reflected wave field for a hydrate formation. The apparatus comprises a hydrate preparation device and a reflected acoustic wave test device, wherein the hydrate preparation device is configured to generate simulated hydrates, and the reflected acoustic wave test device is configured to continuously emit ultrasonic waves to the simulated hydrates in the generation process, process the received reflected waves to identify and extract reflection characteristic information and acoustic wave velocity change information, and continuously monitor the degree of saturation of the simulated hydrates at the same time to obtain a corresponding relationship between the reflection characteristic information and acoustic wave velocity change information and the degree of saturation of the simulated hydrates. The apparatus and method provided by the present invention obtain the reflection characteristics of a hydrate formation and acoustic wave velocity change by acquiring the reflected wave field of the hydrate formation, thereby obtain the relations…
