Abstract
Description
technical field
[0001] This application relates to but not limited to the field of exploration technology, especially a performance testing device for visual packer rubber cartridges. Background technique
[0002] A packer is a downhole operation tool that seals the annulus with a sealing element rubber tube and isolates the production layer to control fluid production or injection and protect the casing. At present, compression packers have a wide range of applications, whether in drilling, exploration or completion processes. Its working principle: Under the action of axial force, the pressure sleeve at one end of the rubber tube produces axial displacement and compresses the rubber tube, making it radially expand and fit the inner wall of the casing, so as to seal the annular gap and prevent liquid leakage. Purpose.
[0003] As a key downhole tool, its main component, the rubber cartridge, must undergo strict performance testing before entering the well to ensure that t...
