Proppant Backflow Testing Device

The proppant backflow testing device can apply closure pressure after the proppant placement is completed, simulating the process of proppant backflow after formation closure; it can also study whether the addition of different new materials to the fracturing fluid can effectively control proppant backflow; during the closure backflow process, the internal changes in proppant, fibers, and other forms can be observed through the model window.
