Embodiment Construction

[0050] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0051] The invention relates to a system for detecting the propagation speed of ultrasonic wave in the sample under the conditions of heating, three-dimensional pressurization and gas adsorption in a tank by using ultrasonic waves. It combines high temperature and high pressure devices to generate high temperature and high pressure, and gas adsorption to simulate the characteristics of natural gas reservoir fluid storage.

[0052] The invention uses a gas adsorption device and a pressurization and heating system to simulate the high temperature and high pressure environment in the underground natural gas reservoir, and at the same time absorbs the characteristics of the real-time display of the ultrasonic testing system, and can dynamically and finely display that the measured object can be gradually pressurized , Under the condition of increasing temperature, the pro...

Abstract

The invention provides a system and a method for testing the supersonic-wave speed of rock under simulated reservoir conditions, and belongs to supersonic-wave detection field. The system for testing the supersonic-wave speed of rock under simulated reservoir conditions comprises a high-temperature high-pressure cabin, a supersonic-wave tester and a gas desorption / adsorption apparatus; a to-be tested sample is disposed in the high-temperature high-pressure cabin; a supersonic-wave probe of the supersonic-wave tester is connected with the to-be tested sample; the gas desorption / adsorption apparatus is connected with the high-temperature high-pressure cabin via a pipe; and the propagation speed of supersonic wave in the to-be tested sample is obtained by using the supersonic-wave tester to test the time of supersonic wave penetrating the to-be tested sample. The system and the method are capable of simulating the pressure high-temperature environment of reservoir rock, supersonic-wave detection is performed on the sample under the conditions of high temperature, high pressure and gas adsorption, and a detection result is finely visually displayed in a data form.

Description

technical field [0001] The invention belongs to the field of ultrasonic detection, and in particular relates to a rock ultrasonic velocity testing system and method for simulating reservoir conditions. Background technique [0002] The ultrasonic testing system is an instrument that uses ultrasonic waves to test the ultrasonic velocity parameters of samples. It can be used in metal and non-metallic mineral resource exploration, urban geophysical prospecting, railway bridge exploration, etc. It is also used to find groundwater, determine reservoir dam foundations and flood control embankments. In hydrological and engineering geological exploration such as hidden danger locations, it can also be used for geothermal exploration. However, the existing ultrasonic testers can only detect objects under normal temperature and normal pressure conditions, and cannot detect the ultrasonic characteristics of the tested samples under the high temperature and high pressure strips and gas ...
