Gel drainage rate testing device and testing method

The present invention relates to a test of special gel ZND gel drainage rate test device and test methods between simulation device for drainage rate in size. Oilfield use special gels and performance studies provide a scientific basis and the necessary experimental data. The technical program: nitrogen bottles connected to the low-pressure line valve, and then connect the intake valve; automatic pressure control device connected to the intake valve and release valve and connect the gas container, gas containers and then move to the left indicating liquid connection pipe installed below drain valve; means about parallel plates formation analog segment connecting the left and right movement instruction catheters, moving in the right directions tube connected with the top of the cylinder, the bottom of the switch associated with a conduit extending into the reservoir cup, cup of liquid on an electronic balance It means a fixed iron behind the front plexiglass plate with screws; on. The test device visualization plexiglass plate intuitive process, using gas as a power source, precise control of pressure; for special gel ZND drainage tests.
