Abstract
The utility model relates to a ground tool used in the underground operation site of the oil field, in particular to a ground backoff device for salvage and other special operations in the underground operation site, at least comprising an inner sleeve tube (1) and an outer sleeve (3); wherein, a holding frame (4) is arranged between the inner sleeve tube (1) and the outer sleeve (3) to form a body, an upper hub (5) and a lower hub (2) are arranged on the upper and the lower end of the outer sleeve (3) separately, the external diameter of the body is from 500mm to 800mm, the length of the body is from 1500mm to 1800mm, the external diameter of the inner sleeve (1) is from 140mm to 160mm, the wall thickness of the inner sleeve (1) is from 10mm to 20mm, the holding frame (4) is fixed with a reinforcement (6). The utility model has the advantages of convenient operation, safety and reliability, reasonable structure and strong applicability.
Description
Technical field
The utility model relates to a kind of oilfield downhole operation field ground instrument, and particularly the on-the-spot salvaging of underground work waits the instrument of special operation back-off, the ground reverse buckling equipment of definitely saying so.
Background technology
Wait in the job execution in on-the-spot salvagings of oilfield downhole operation, run into the problem that downhole oil pipe thread, drilling rod button are not opened, need to use the equipment such as rotating disk of special use.Because special-purpose equipment price height such as rotating disk, equipment is big, only just can call when the problems referred to above or equipment rebuilding occurring.Therefore, use at the special-purpose inconvenient scene of equipment such as rotating disk.
Summary of the invention
The purpose of this utility model provides a kind of ground back-off device, and it is esy to use, safe and reliable, and is rational in infrastructure, and application performance is strong.
The purpose of this utility model is achieved in that the ground reverse buckling equipment, it is characterized in that: which comprises at least inner sleeve 1, overcoat 3, have bracing frame 4 to constitute body between inner sleeve 1 and the overcoat 3, overcoat has last hub 5 and following hub 2 in two ends about in the of 3.
Described body diameter is between 500-800mm, and height is between 1500-1800mm.
The external diameter of described inner sleeve 1 is between 140-160mm, and wall thickness is at 10-20mm.
Described bracing frame 4 is fixedly connected with reinforcing rib 6.
Characteristics of the present utility model are: owing to be connected as a single entity by columnar stays frame 4 between inner sleeve 1 and the overcoat 3, overcoat 3 is fastening by last hub 5 and following hub 2 again, and entire outer diameter is chosen between the 500-800mm, and length is between 1500-1800mm.Therefore its is rational in infrastructure simple, and the reliability height is easy to manufacture.Greatly facilitate on-the-spot the use.During work, drilling rod or oil pipe are linked to each other with ground reverse buckling equipment body, wire rope is twined on the coat, being used as power with workover rig drives the tubing string rotation, realizes back-off operation.It has following characteristics:
1, this instrument uses easy to operate.
2, safe and reliable, not fragile.
3, simple in structure, to draw materials conveniently, processing is simple.
4, this instrument is applicable to that field condition uses, and is widely used in operations such as salvaging, thread making, back-off.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment accompanying drawing.
Fig. 1 is that the utility model embodiment master looks schematic diagram;
Fig. 2 is the utility model embodiment schematic top plan view.
Among the figure, 1, inner sleeve; 2, following hub; 3, overcoat; 4, bracing frame; 5, go up hub; 6, reinforcing rib.
The specific embodiment
As depicted in figs. 1 and 2, the ground reverse buckling equipment comprises that inner sleeve 1, overcoat 3, bracing frame 4 constitute body, and the external diameter of inner sleeve 1 is 140mm, and wall thickness is 10mm, and this body diameter is that 500mm, length are 1500mm.Or the external diameter of inner sleeve 1 is 160mm, and wall thickness is 20mm, and this body diameter is that 800mm, length are 1800mm.External diameter that also can inner sleeve 1 is chosen between the 140mm-160mm, and wall thickness is chosen in 10-20mm.This body diameter is chosen between the 500mm-800mm, and length is chosen between the 1500-1800mm.Overcoat has last hub 5 and following hub 2 in two ends about in the of 3, and last hub 5 and following hub 2 can be socketed on the overcoat 3 by metal tube processing and both can reinforce, and wire rope is wrapped between hub 5 and the following hub 2, are fixedly connected with reinforcing rib 6 on the bracing frame 4.Its reasonable integral structure is simple, and the reliability height is easy to manufacture, greatly convenient on-the-spot the use.During work, drilling rod or oil pipe are linked to each other with ground reverse buckling equipment body, wire rope is twined on the coat, being used as power with workover rig drives the tubing string rotation, realizes back-off operation.
Claims (4)
1. ground reverse buckling equipment is characterized in that: which comprises at least inner sleeve (1), overcoat (3), have bracing frame (4) to constitute body between inner sleeve (1) and the overcoat (3), overcoat (3) two ends up and down has last hub (5) and following hub (2).
