Overview

      The device researches the gas-liquid percolation physical model and data acquisition and processing in the condition of simulated coal reservoir.It automatically control to load triaxial confining pressure to simulate the stress changes in the process of reservoir mining.It has backpressure setting control function to establish the experiment with stratigraphic condition.Under the simulation stratigraphic condition,it can also develop single factor coalbed gas physical simulation experiment like cap rock,temperature,pressure and so on.It can also analyse the influence of some single factor such as cap rock breakthrough pressure,temperature,pressure to coalbed gas accumulation.At the same time,It does the experiment of the maximum pressure of a gas breakthrough rock sample.It can also research the cap rock sealing ability in different conditions.
