Abstract
The invention discloses a pulling type workover drill floor which is used for mounting a rotary disc, bearing the weight of underground pipes and tubular tools, storing tools, storing three-joint units, mounting a well mouth blowout preventer and providing work space for operation during work. The workover drill floor is of a front-back split type pulling structure. Stand columns are made from round tubes, inner tubes are sleeved with outer tubes, the upper floor surface is fixed to the outer tubes, and the lower floor surface is fixed to the inner tubes. The workover drill floor is pulled out to increase the height during work, and retracted to decrease the height during transportation, and the problem of conflict between work and transportation is solved. The workover drill floor is mainly composed of a boat-shaped base, a derrick foundation, a rotary disc base, a three-joint unit base, a floating driller platform, supporting rods, a ramp, a blowout preventer assembling and transferring device, a climbing chain box, an escaping slide way and the like. A workover drill floor body is composed of the rotary disc base and the three-joint unit base, and the rotary disc base and the three-joint unit base are pulled and retracted through a lifting system of a workover rig and fixed through pin shafts after being pulled and retracted. The pulling type workover drill floor is compact in structure, fully equipped, good in using stability and convenient to mount, does not exceed the limit when transported and does not need to be mounted in cooperation with a crane.
Description
Technical field
The invention belongs to petroleum works equipment technical field, relate to a kind of drawing and pulling type well workover rig floor for workover rig.
Background technology
There are the following problems for existing workover treatment equipment and workover process: workover treatment needs shaft mouth operation platform, is used for
Install rotating disk, bear downhole tubular tool weight, storing tools, put thribble, when operation for operation provide work space, its table top
Lower space is used for installing wellhead blowout preventer.Workover platform is frame structure, is limited by working space and wellhead assembly, rig floor
Overall dimensions relatively big, limit beyond transport, it is difficult to realize the resettlement between well site.Prior art is designed as parallelogram
Revolve and rise structure or case stacked structure, but combination installation difficulty is big, rig floor poor stability, and be required for crane cooperation installation, warp
Help of poor benefits.
Summary of the invention
For solving the defect that prior art exists, invent a kind of drawing and pulling type well workover rig floor.
The technical solution used in the present invention: split type drawing structure before and after the employing of described rig floor, column pipe makes, outward
Pipe box inner tube, upper table surface and outer tube are fixed, and following table and inner tube are fixed, and extracting out during operation increases height, retract and reduce during transport
Highly, operation and the contradiction of transport are solved.
The well workover rig floor that the present invention relates to mainly is waftd platform, support by boat shaped base, derrick footing, rotary disk basement, thribble seat, driller
Bar, ramp, preventer assemble board migration device, the climbing composition such as chain box, escaping slideway.Described rig floor body be divided into rotary disk basement and
Thribble seat, pull rises and puts respectively, hoists and falls in vertical displacement, fixing with bearing pin respectively after extracting out and retracting.Described fixing
Bearing pin is mutually perpendicular to, and during by shearing force, maintains rig floor stable.Described rotary disk basement is connected with thribble seat connecting rod, derrick footing
And strut is set between the rotating disk seat of honour, increase the stability of rig floor.Described configuration boat shaped base, increases the ground plane of workover rig
Long-pending, strengthen equipment availability stability.
The technical characteristic of the present invention also has: configuration ramp is easy to pipe and is had the guiding of upper and lower rig floor.Configuration escaping slideway is easy to
In emergency circumstances personnel quickly flee from well head.
Rig floor rotary table seat is provided with climbing chain box, transfers power to rotating disk, upright post sleeve by climbing chain box
Multiple fixing hole, the movement between general well site are set between pipe, chain box can not be pulled down and directly transport.
Enough spaces are had for installing well head four-way and a whole set of blowout preventer set, equipped with well head go-cart etc., side under rig floor
Just wellhead equipment installation, dismantle and migrate.
Utilize the lifting system of workover rig, the pull of rig floor can be realized smoothly and rise and put.
Compared with prior art, present configuration is compact, comprehensive, and stability in use is good, does not transfinites during transport, installs
Convenient, it is not required to crane and coordinates installation.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention.
Described above is only presently preferred embodiments of the present invention, and above-mentioned specific embodiment is not limitation of the present invention,
Retouching that all those of ordinary skill in the art are made as described above, revise, increase and decrease or equivalent, belong to the present invention
Protection domain.
