Description
Technical field
The present invention relates to a kind of oil drilling and extracting equipment technical fields, are related to a kind of promotion oil pipe device of downhole hanger.
Background technique
Want tripping in hanger that well oil pipe is suspended on the big four of wellhead assembly when oil field oil water well operations, hanger
Also to play a part of to seal tubing and casing, prevent the highly pressurised liquid of hanger or more from leaking into casing, therefore, have on hanger
Sealing ring.Hanger during tripping in will pass through preventer, due to derrick inclination cause hanger cannot honest tripping in, often
The problem of flashboard in preventer hangs the sealing ring on bad hanger occurs.In order to solve hanger sealing ring during tripping in
Bad problem is hung, is to push the oil pipe being connected on hanger from one direction another party of deflection with manpower at the scene, but manpower
Push it is not only time-consuming and laborious, it is uncertain that hanger can be made placed in the middle, and operator will bow observation close to well head, cannot hide
Burst accident is kept away, there are security risks.
Summary of the invention
The problem to be solved in the present invention is made in view of the above problems, provide a kind of promotion oil pipe device of downhole hanger
It will not hang bad sealing ring, and easy, safety when preventer is passed through in hanger tripping in, time saving and energy saving.
To solve the above problems, the technical scheme adopted by the invention is that:
A kind of promotion oil pipe device of downhole hanger, including promote oil pipe, sealing ring, hanger, preventer, connection spiral shell
Bolt, sealing ring are mounted on hanger, are promoted oil pipe lower part and are connect with hanger, well oil pipe is connected under hanger, is also wrapped
Idler wheel, wheel carrier, bracket, pedestal, support rod, adjusting screw rod, support base are included, pedestal is fixed on preventer by connection bolt, bottom
There is track groove on seat, there is screw hole in the right side of pedestal, and the internal screw thread of this screw hole and the external screw thread of adjusting screw rod are mating, adjusting screw rod
It is passed through in rear injection slot from the right side screw hole of pedestal, support base is sleeved on the left end of adjusting screw rod, and support base is in track
In slot, the lower end of support rod and support base hinge connection, the upper end of support rod and the lower part hinge connection of bracket, the lower end of bracket
With pedestal hinge connection, wheel carrier is mounted on the top of bracket, idler wheel is installed on wheel carrier, idler wheel is close to the outside for promoting oil pipe.
Roller surface is equipped with circular arc slot, and the radius of circular arc slot is identical as the radius of oil pipe is promoted.
The right side screw hole screw thread of adjusting screw rod external screw thread and pedestal is rectangular thread, screw pitch 4-6mm.
The present invention takes above technical scheme, has the advantage that
The present invention can be pushed using rotation adjusting screw rod and be promoted the bosom position that oil pipe is at preventer,
Hanger tripping in will not will not be hung when passing through preventer bad with the rams contact in preventer, the sealing ring on hanger, be protected
Card is constructed successfully, and operation is avoided to do over again, rotation adjusting screw rod energy righting hanger, easy, quick, time saving and energy saving, operator
Member does not have to that safety accident will not occur close to well head.
Detailed description of the invention
Fig. 1 is structural schematic diagram of the invention.
Specific embodiment
Referring to Fig. 1, including promote oil pipe 1, idler wheel 2, wheel carrier 3, bracket 4, sealing ring 5, hanger 6, preventer 7, connection
Bolt 8, pedestal 9, support rod 10, adjusting screw rod 11, support base 13, sealing ring 5 are mounted on hanger 6, promote 1 lower part of oil pipe
It is connect with hanger 6, well oil pipe is connected under hanger 6 and passes through preventer 7, pedestal 9 is fixed on blowout prevention by connection bolt 8
On device 7, there is track groove 11 on pedestal 9, there is screw hole in the right side of pedestal 9, the internal screw thread of this screw hole and the outer spiral shell of adjusting screw rod 12
Line is mating, and adjusting screw rod 12 passes through in rear injection slot 11 from the right side screw hole of pedestal 9, and support base 13 is sleeved on adjusting spiral shell
The left end of bar 12, support base 13 is in track groove 11, and support base 13 can only walk in track groove 11 to be rotated, support rod
10 lower end and 13 hinge connection of support base, the upper end of support rod 10 and the lower part hinge connection of bracket 4, the lower end of bracket 4 with
9 hinge connection of pedestal, wheel carrier 3 are mounted on the top of bracket 4, install idler wheel 2 on wheel carrier 3, and idler wheel 2 can rotate on wheel carrier 3, roll
Wheel 2 is close to the outside for promoting oil pipe 1.2 surface of idler wheel be equipped with circular arc slot 14, the radius of circular arc slot 14 with mention
The radius for rising oil pipe 1 is identical, to come into full contact with promotion oil pipe 1, does not wear and promotes oil pipe 1.Adjusting screw rod 12
External screw thread and pedestal 9 right side screw hole screw thread be rectangular thread, screw pitch 4-6mm, rectangular thread transmit torque it is big, spiral shell
Fast away from big walking, passage is fast.
It to be in the skewed side of hanger 6 when pedestal 9 is mounted on preventer 7, rotates adjusting screw rod 12, adjusts spiral shell
Bar 12 is walked, and support base 13 cannot rotate in track groove, but can walk together with adjusting screw rod 12, make 10 lower end of support rod
It walks together, pushes the idler wheel 2 on bracket and promote oil pipe 1 to center position, then decentralization promotes oil pipe 1, makes hanger 6
Preventer 7 is passed through, the sealing ring 5 on hanger 6 will not be hung bad by the flashboard in preventer 7.When promoting the decentralization of oil pipe 1
It is rolling friction with idler wheel 2, it can be along unobstructed downlink.
The foregoing is merely presently preferred embodiments of the present invention, non-to limit the scope of the patents of the invention, other are with this
The equivalence changes of the patent spirit of invention should all belong to the scope of the patents of the invention.
