Description

Technical Field

[0001] The utility model relates to the technical field of hangers, in particular to an internal slip liner hanger. Background Technique

[0002] The internal slip liner hanger is a tool for fixing the liner in oil and gas drilling. Its core function is to safely hang the liner on the inner wall of the casing through the biting action of the slips. This device has the advantages of large flow area and strong bearing capacity, and has been widely used in cementing construction of deep wells and ultra-deep wells.

[0003] When maintaining and servicing the existing hanger, after the equipment is lifted out of the well, it should be cleaned in time, especially the reverse nut of the reverse connection joint, the thrust bearing and the sealing cartridge core. However, when cleaning the storage box for placing parts, there is dust inside the storage box, and more water and energy are required when cleaning the storage box. Therefore, an internal slip liner hanger is needed to efficiently clean the storage box and improve the efficiency of maintaining the hanger. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an internal slip liner hanger to solve the problem proposed in the above background technique that when maintaining and servicing the existing hanger, after the equipment is lifted out of the well, it should be cleaned in time, especially the reverse nut of the reverse connection joint, the thrust bearing and the sealing cartridge core.
