An ultrasonic vibration-based test system for the study of coalbed gas

Based on the influence of ultrasonic vibration on the adsorption/desorption and seepage characteristics of coalbed gas,a test system for the measurement of adsorption and seepage characteristics of coalbed gas was designed.The main component of the system is a pressure testing device.The test system consists of six parts,including an intelligentized acoustic generator, adsorption and seepage devices,a pressure supply,a deformation measurement component,a gas supply and a deformation tester.The function and operating method of the test system were introduced in detail.Experimental results show that the test system can meet completely the requirements for the characterization of adsorption/desorption and seepage of coalbed gas in either the presence or absence of an ultrasonic field.
