Abstract
A device and a method for early monitoring of gas intrusion based on pressure wave propagation are provided in the present disclosure. The technical solution is as follows. The lower end of the liquid storage tank is connected to the simulated wellbore through a liquid injection pipeline, a centrifugal pump, a pressure-stabilizing water tank, and a mass flowmeter. One end of the gas storage tank is connected to a screw air compressor, while the other end is connected to the simulated wellbore through an injection pipeline and a micro-orifice flowmeter. The gas-liquid mixer is provided at the upper end of the simulated wellbore, with the pressure-disturbing device connected below it. Multiple pressure sensors are provided at the middle of the simulated wellbore and connected to the computer via wires and an oscilloscope.
