The instrument can conduct the following studies under simulated formation pressure and temperature conditions:

1. Determination of liquid permeability

At a certain flow rate, the liquid is passed through the core. By measuring the pressure difference between the inlet and outlet of the core and the flow rate of the liquid flowing through the core, combined with other parameters, the permeability of the core liquid is calculated according to Darcy's law.

2. Liquid flowability experiment

Under certain pressure and temperature conditions, study the laws of relevant parameters such as pressure, temperature, flow rate, etc. during the process of fluid flow through rock cores.
