Overview

      The swellable type of polymer particle is a kind of material whose volume will expand after sop up, it will not absorb oil, and the volume of water gel will shrink in oil.This instrument can infuse the swellable particle that still has very good flexibility after absorbing water into the standard laser micro size orifice plate, then measure the strength of the swellable particle. Besides, the swellable particle after absorbing water can be infused into the simulated formation pore, and the deformation of them under the water flooding pressure may driving residual oil migration in the pore, so this device can also simulate the effect of displacement of reservoir oil.
