Abstract
A kind of sleeve pipe tieback righting-oriented device, belongs to oilfield downhole operation technical field.Grafting joint is threaded with righting cylinder body, and righting cylinder chamber body forms make-up tieback storehouse, and righting cylinder body is threaded with guiding guide shoe.The utility model has the advantages that and utilize major diameter guiding guide shoe in well, to set right in the sleeve pipe of middle position not, guiding well inner sleeve enters in sleeve pipe tieback righting-oriented device, aligns between two parties, thereby realize the success of sleeve pipe make-up tieback with the tie-back casing being lowered to.
Description
Technical field
The utility model relates to a kind of sleeve pipe tieback righting-oriented device, belongs to oilfield downhole operation technical field.
Background technology
At present, oil gas water well overhaul get buy or get by illegal means after when make-up tieback, to the sleeve pipe of lower same model in well, be lowered to sleeve pipe foot screw buckle by direct and well inner sleeve screw thread tieback, because down-hole actual conditions are comparatively complicated, make-up tieback well section may exist cementing quality poor, cause the reasons such as mineshaft diameter is larger, make well inner sleeve amesiality, there is sleeve pipe situation not placed in the middle, the screw thread of the tie-back casing being lowered to is difficult to align tieback success, secondly, even if tieback success, also may exist tieback askew, tiltedly button phenomenon, later stage pressure testing is leaked, cause construction many drawbacks such as unsuccessfully.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of sleeve pipe tieback righting-oriented device.
A kind of sleeve pipe tieback righting-oriented device, grafting joint is threaded with righting cylinder body, and righting cylinder chamber body forms make-up tieback storehouse, and righting cylinder body is threaded with guiding guide shoe.
The utility model has the advantages that and utilize major diameter guiding guide shoe in well, to set right in the sleeve pipe of middle position not, guiding well inner sleeve enters in sleeve pipe tieback righting-oriented device, aligns between two parties, thereby realize the success of sleeve pipe make-up tieback with the tie-back casing being lowered to.
Brief description of the drawings
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, does not form to improper restriction of the present utility model, wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Detailed description of the invention
Obviously the many modifications and variations that, those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of sleeve pipe tieback righting-oriented device, is that one is bought or get by illegal means the rear successful special tool of sleeve pipe make-up tieback that ensures for getting.
A kind of sleeve pipe tieback righting-oriented device, a kind of sleeve pipe tieback righting-oriented device, grafting joint 1 is threaded with righting cylinder body 2, and righting cylinder body 2 inner chambers form make-up tieback storehouse 3, and righting cylinder body 2 is threaded with guiding guide shoe 4.
Oil gas water well overhaul is got while buing or get by illegal means rear make-up tieback, need be to the sleeve pipe of lower same model in well, first on ground, grafting joint 1 is enclosed within to tie-back casing male thread with upper body bottom, electric welding grafting joint 1 and sleeve body are fixed, righting cylinder body 2 is threaded with grafting joint 1, male (or female) screw thread of tie-back casing is interior reserved to buckling button distance in sleeve pipe tieback storehouse 3, then guiding guide shoe 4 and righting cylinder body 2 are threaded, and completes ground instrument assembling.In well, be lowered to make-up tie-back casing to precalculated position, revoling tube tubing string string, guiding guide shoe 4 sets right well inner sleeve to enter inner chamber, put down sleeve pipe tubing string string well inner sleeve gently and enter sleeve pipe tieback storehouse 3 and contact with make-up tieback screw thread, rotation is also slowly transferred sleeve pipe tubing string string and is completed the construction of sleeve pipe make-up tieback.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
