STAND FOR TESTS OF MECHANICAL-HYDRAULIC PACKERS OF BILATERAL ACTION Russian patent published in 2017 - IPC G01M3/00 E21B33/12 

FIELD: testing equipment.

SUBSTANCE: stand for testing mechanical-hydraulic packers of bilateral action contains a simulator of the casing, mounted horizontally on a stationary frame, hollow simulator of production tubing, packer and rod-stub, placed in through hole of casing and interconnected, front sealing unit is installed between hollow simulator of production tubing, that provides tightness of the zone above packer, rear sealing unit is installed between rod-stub and casing simulator that provides tightness zone above packer, hydro station to create axial load on packer through hollow simulator of production tubing by hydraulic cylinder rod, pumping installation for supply and drainage of water in zone above and under pacher, as well as through the hollow simulator of production tubing into the inner cavity of the packer. To verify the displacement of the packer relative to the casing simulator, the end of the rod-stub is set at a reference distance h from the end of the rear sealing unit. The hydraulic cylinder is mounted on a mobile frame with the ability to move along the axis of casing simulator and ability for docking -undocking with the casing simulator through the adapter, as well as with the possibility of docking-undocking rod of hydraulic cylinder with the hollow production tubing simulator. Removing the packer from casing simulator is possible with removable tool, installed between rod of hydraulic cylinder and hollow production tubing simulator and entered using hydraulic cylinder rod through the hollow production tubing simulator into the inner cavity of packer.

EFFECT: expansion of the functionality of the stand.
