Abstract
A screen test apparatus includes a test cell disposed within a pressure vessel, a piston disposed within the pressure vessel, wherein the piston is in sealing contact with an inner surface of the pressure vessel, and a screen assembly disposed in an end of the test cell. The screen assembly includes a mount collar, a screen disposed in the mount collar, and an end cap adjacent the screen which includes grooves in a face adjacent the screen and passages extending through the end cap, wherein the screen assembly is configured to fully support the screen while allowing a fluid to pass through the screen.
Claims18
A screen test apparatus comprising:
- a test cell disposed within a pressure vessel;
- a piston disposed within the pressure vessel, wherein the piston is in sealing contact with an inner surface of the pressure vessel;
- and
- a screen assembly disposed in an end of the test cell, the screen assembly comprising:
- a mount collar;
- a screen disposed in the mount collar;
- an end cap adjacent the screen comprising grooves in a face adjacent the screen and passages extending through the end cap;
- wherein the screen assembly is configured to fully support the screen while allowing a fluid to pass through the screen.
A screen test system comprising:
- a pumping assembly comprising:
- a pump, a fluid reservoir, and a pressure regulator;
- a screen test apparatus comprising:
- a test cell disposed within a pressure vessel;
- a piston disposed within the pressure vessel, the piston in sealing contact with an inner surface of the pressure vessel;
- a screen assembly disposed in the test cell, the screen assembly comprising:
- a mount collar;
- a screen disposed in the mount collar;
- an end cap adjacent the screen comprising grooves in a face adjacent the
- screen and passages extending through the end cap.
- a fluid line connecting the pumping assembly to the screen test apparatus;
- a workover fluid to apply pressure to the screen assembly;
- and
- a hydraulic fluid to apply pressure to the piston.
A method of testing a screen with high pressure, the method comprising:
- disposing a test cell and a piston within a pressure vessel, such that the piston is in sealing contact with an inner surface of the pressure vessel;
- disposing a screen assembly in the test cell, the screen assembly comprising:
- a mount collar;
- a screen disposed in the mount collar;
- an end cap adjacent the screen comprising grooves in a face adjacent the screen and passages extending through the end cap.;
- filling a volume in the pressure vessel between the piston and the test cell with a workover fluid, the workover fluid configured to apply a pressure against the screen assembly;
- filling a remaining volume in the pressure vessel with a hydraulic fluid, the hydraulic fluid configured to apply pressure to the piston;
- applying pressure from a pumping assembly with the hydraulic fluid to the piston;
- and
- applying pressure with the workover fluid to the screen assembly;
- wherein the workover fluid applied to the screen assembly is pressurized to determine sealing characteristics.
