Screen casing is squeezed；Another method is that screen casing is put into high-pressure bottle, and closure slurry is injected high pressure using high-pressure pump
In container, the filter hole of screen casing seamed on the outside of the screen casing it is stifled after, improve epipolar restriction to squeeze screen casing.The first side
There are larger difference, the reality of test result and screen casing with practical fashion of extrusion of the screen casing in oil well for the fashion of extrusion of method
Collapse resistance difference is larger；The experimental rig of second method is of high cost, high to the performance requirement of high-pressure pump, to blocking slurry
Requirement it is high, test operation is complicated, and screen casing often occur during actual test cannot be blocked very well, not play height
The case where pressure, to affect the result of testing experiment.
Therefore, it is necessary to a kind of new test device be provided, to overcome drawbacks described above.
