The application discloses a kind of
visualization test device and method of
porous medium displacement under different gravity.The
microfluidic chip model module, displacement injection module,
image acquisition module and
light source module are placed in model box shell, the model box shell is placed in the basket of
centrifuge, fluid is stored in displacement injection module, for providing fluid for
microfluidic chip model module, displacement injection module is connected with
microfluidic chip model module,
image acquisition module is used to collect
optical image information of microfluidic
chip model module in fluid displacement process;Method includes
dyeing original fluid, installing microfluidic
chip, using
injection pump to push
plastic syringe to inject fluid into microfluidic
chip, and observing the flow migration mode and fluid distribution of fluid displacement process in
porous medium.The device of the application is simple and easy to manufacture, easy to operate, and has high stability, uses
supergravity and microgravity for
model test, realizes real-time observation on two-phase fluid displacement process.
