Description
Technical field
This utility model is related to cutting technique field, more particularly to drilling tool is reclaimed in a kind of cutting of deep water well head system.
Background technology
With the oil production equipment that deep-sea oil gas exploration and development increase in demand and marine field are built increasing, country
Abyssal floor cleaning is required stricter.According to seabed abandoned well specification, 5m below mud line must not leave and various throw aside thing.Currently
China comes into the deep-water exploration stage, due to being affected by drilling region sea situation, is reclaimed with traditional cutting recovery method
Subsea wellheads system becomes extremely difficult, and external large-scale petroleum service company can carry out abandoned well operation, and each operation company has
Oneself special abandoned well power tool, and China's abandoned well operation is monopolized by foreign countries.According to prediction data, the coming years are domestic marine
Works and Oil/gas Well are thrown aside, and workload is heavy, and market potential is huge.
In summary, prior art there will naturally be inconvenience and defect in actual use, it is therefore necessary to being improved.
Utility model content
For above-mentioned defect, the purpose of this utility model is that providing a kind of deep water well head system cutting reclaims drilling tool,
Which can solve the above problems.
To achieve these goals, this utility model provides a kind of deep water well head system cutting and reclaims drilling tool, including outside
Hanger, underwater well head, guide base, the first centralizer, sleeve pipe, telescopic compensator, conduit, cutter and the second centralizer, 2
Underwater well head is separately positioned on the left and right sides of outside hanger, and guide base is arranged on outside hanger bottom, guide base
Arrange on the ground, the first centralizer is connected to lower section in the middle part of outside hanger, 2 sleeve pipes are separately positioned in 2 underwater wells
Mouth medial part, telescopic compensator one end are connected to the first centralizer bottom, and the other end is connected on cutter, and 2 conduits are set respectively
Put in the outside of 2 underwater well heads, the second centralizer is connected to the bottom of cutter.
Outside hanger includes that detent mechanism, well head head and rotating mechanism, detent mechanism are arranged on a left side for outside hanger
Right both sides, detent mechanism bottom are provided with well head head, and rotating mechanism is arranged on the left and right sides of outside hanger middle and lower part.
Casing diameter is 508mm, and conduit diameter is 762mm.
Detent mechanism includes that claw, claw are mutually engaged with well head head.
This utility model is reasonable in design, easy to use, adopts screw drill using pull-type well head system cutting recovery instrument
Tool drives cutter circumgyration incision sleeve pipe, drastically increases cutting efficiency and precision, saves the working time.
Description of the drawings
Fig. 1 is overall structure diagram of the present utility model；
Fig. 2 is outside hanger structural representation of the present utility model.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only in order to explaining
This utility model, is not used to limit this utility model.
Referring to Fig. 1, drilling tool is reclaimed in a kind of deep water well head system cutting, including outside hanger 1, underwater well head 2, is oriented to base
The 3, first centralizer 4 of seat, sleeve pipe 5, telescopic compensator 6, conduit 7,9,2 underwater well heads 2 of cutter 8 and the second centralizer are set respectively
Put in the left and right sides of outside hanger 1, guide base 3 is arranged on 1 bottom of outside hanger, guide base 3 is arranged on ground
On, the first centralizer 4 is connected to lower section in the middle part of outside hanger 1, and 2 sleeve pipes 5 are separately positioned in 2 underwater wells, 2 mouthfuls of inner sides
Portion, 6 one end of telescopic compensator are connected to 4 bottom of the first centralizer, and the other end is connected on cutter 8, and 2 conduits 7 are respectively provided with
In the outside of 2 underwater well heads 2, the second centralizer 9 is connected to the bottom of cutter 8.
Outside hanger 1 includes that detent mechanism 10, well head head 11 and rotating mechanism 12, detent mechanism 10 are arranged on outside outstanding
The left and right sides of hanging device 1,10 bottom of detent mechanism are provided with well head head 11, under rotating mechanism 12 is arranged in outside hanger 1
The left and right sides in portion.
Casing diameter is 508mm, and conduit diameter is 762mm.
Detent mechanism includes that claw 13, claw are mutually engaged with well head head.
High-pressure well is oral for locking for outside hanger, and keeps lifting state of the cutting tool to well head head；Enter under
During well head, supporting positive cover is supported on internal surface of sleeve pipe, it is ensured that the centering and stability of whole cutting tool, prevents from shaking
And cut partially；After entering predetermined cuts position under cutter, turn on pump is circulated, and is gradually increased discharge capacity, and highly pressurised liquid is caused by nozzle
Piston is moved downward, and bearing pin of the cutter under piston thrust effect in cutter body is rotated, and is opened and is withstood tube wall entrance cutting shape
State；Top connects helicoid hydraulic motor and drives cutter rotation to complete casing-pipe cutting by drilling fluid drive motor.
Detent mechanism holds well head tightly by catching, and rotating mechanism drives cutter rotation by helicoid hydraulic motor hydro powered, with
The action request of lifting cutting and plug-in recovery needed for completing.
In sum,
Certainly, this utility model can also have other various embodiments, spiritual and its substantive without departing substantially from this utility model
In the case of, those of ordinary skill in the art work as and can make various corresponding changes and deformation, but these according to this utility model
Corresponding change and deformation should all belong to the scope of the claims appended by this utility model.
