The supercritical CO₂ injection core power generation testing instrument is a device specifically designed to study the flow behavior of supercritical CO₂ in cores and its impact on the electrical properties of the cores. It can simulate geological environments under high temperature and high pressure conditions, providing key data support for research on geological sequestration, oil displacement, and geothermal development. Changes in the acoustic waveform of the rock sample after supercritical carbon dioxide injection; By using the ultrasonic pulse transmission method, the propagation time of longitudinal waves or transverse waves along the length of the rock sample is measured, and the longitudinal and transverse wave velocities of the rock sample are calculated; Through the analysis of the acoustic attenuation coefficient, the changes in the acoustic characteristics of the reservoir caprock after supercritical carbon dioxide injection are evaluated.
