Abstract
A mineshaft-stratum fracture coupled flowing simulation experiment device includes a simulated mineshaft flowing system, a simulated stratum system, a simulated fracture system and a data acquisition system. The simulated mineshaft flowing system includes simulated mineshaft, simulated drilling rod, drilling fluid storage tank, stirring motor, and drilling fluid screw pump. The simulated drilling rod is located in center of the simulated mineshaft. The stirring motor is provided in the drilling fluid storage tank. The drilling fluid screw pump is connected to an inlet end of the simulated drilling rod through the drilling fluid storage tank. The simulated stratum system includes simulated stratum, clean water storage tank, separation tank, gas storage tank, gas air-compressor, and clean water screw pump. The gas storage tank is connected to the gas air-compressor and is connected to the simulated stratum through a gas pressure regulating valve.
