Abstract
The utility model relates to a simulator for observing fluid flow in a porous medium. The simulator is characterized by comprising a simulator body used for observing fluid flow in a porous medium. A shell comprises a front cover and a bottom board, and the middle of the front cover is hollow and is communicated with an observing board. A pore template is parallelly fixed behind the observing board and abuts against the observing board through a backpressure mechanism so that no gap exists between the pore template and the observing board at the front end, and the rear end of the backpressure mechanism enables a shell to be integrally sealed through the bottom board. By means of the simulator, fluid flow in a porous medium in the low-temperature (or high-temperature) state can be observed. The simulator is used for observing, simulating and analyzing flow condition of a fluid such as oil, water, gas, foam and colloid in a porous medium.
