Embodiment Construction

[0041] see first Figure 1-3 Examples shown in .

[0042] figure 1 with figure 2 A wellbore tubing protection device 1 according to the invention is shown in a mounted state to a wellbore tubing end 7 . The device 1 is provided for protecting the external thread 8 of the pipe end 7 . In the installed state shown, the device 1 can be manually operated so that its state is in the locked state ( figure 2 shown in ) and the unlocked state ( figure 1 shown in ) alternate between. In the locked state, the device 1 is fixed to the pipe in such a way that it prevents the protection device from being separated from the pipe due to some accidental external impact. In the unlocked state the device 1 is less securely fixed to the pipe than in the locked state and the device can be manually removed from the pipe.

[0043] The device 1 comprises a covering sleeve 2 and an actuating part 3 .

[0044] The cover sleeve 2 comprises a peripheral sleeve wall 21 with a central axis 5 ....

Abstract

A wellbore pipe protection device (1) comprises a covering sleeve (2) and an actuating element (3). The actuating element is arranged to change the deformation state of a sleeve wall (21) of the covering sleeve in order to realise interchangeability between a locked condition and an unlocked condition of the protection device. In the locked condition, elastic material (4) is being pressed by the sleeve wall into screw thread (8) of a wellbore pipe end (7). The actuating element comprises a handgrip (9) which, relative to the covering sleeve, is manually slidable in axial direction (5) and, in the locked condition, manually rotatable about the axial direction into a rotation position in which axial slidability of the actuating element is blocked in a direction towards the unlocked condition.

Description

technical field [0001] The invention relates to a wellbore pipeline protection device, which is used for protecting the thread at the end of the wellbore pipeline in the state of being installed on the end of the wellbore pipeline. Background technique [0002] As is well known, references to the term "wellbore tubing" in the prior text are intended to include all types of tubing used when conducting wellbore operations, both during the drilling phase and during the generation phase. Thus, the term "wellbore tubing" includes all types of drill bits, casings and tubulars used in a wellbore. [0003] This protective device is used to protect the internal or external thread of the end of the wellbore pipe from potential damage during the transportation and storage of the wellbore pipe. When the wellbore tubing is in operation, ie the wellbore tubing is interconnected to form a tubing string, the protective device has been removed from the tubing ends. [0004] In fact, variou...
