<p>Provided is an apparatus for testing a dense rock gas desorption rate, which is composed of a gas desorption apparatus, a gas volume measurement apparatus and a computer. The gas desorption apparatus comprises a core gripper, a boost pump and a pressure gauge; the gas volume measurement apparatus comprises a gas storage tank, a rubber hose, a quality measurement instrument, a special liquid, a liquid storage tank and a thin film, the gas storage tank storing the special liquid, and the liquid storage tank storing the special liquid; with the core gripper producing circling pressure, gas in a rock sample is desorbed and is discharged to the gas storage tank through a valve, and the gas discharges the special liquid in the gas storage tank to the liquid storage tank; the weight of the discharged special liquid is measured by the quality measurement instrument and is transmitted in real time via a data transmission line to the computer to record the weight of the special liquid discharged in real time, and the computer automatically calculates the volume of the special liquid discharged in real time with the known density of the special liquid; and the computer calculates the desorption rate of the rock sample according to the volume of the special liquid discharged in real time.</p> |
