Background technology
In petroleum drilling operation, every mouthful of well has casing job, when setting of casing, usually because of top, drive with hook and well head middle sleeve box vertical center degree and cause not button difficulty, a sleeve pipe often needs make-up ten minutes, and 20 minutes, even for more time, greatly increased labour's expenditure, wasted a large amount of production times, significantly reduced production efficiency, be unfavorable for cost-saving.
Utility model content
The purpose of this utility model is to provide a kind of simple in structure, easy to operate casing centering guide, to solve low, the tedious defect of prior art middle sleeve make-up efficiency.
The technical solution of the utility model is: comprise that the righting portion on top and the guiding of bottom are to oral area, described righting portion comprises for the symmetrical traversing carriage slide block that is movably fixed to derrick crossbeam two sides of a ship respectively, the inner side of described traversing carriage slide block is fixing telescoping cylinder that can transversal stretching respectively, and the sleeve pipe hand identical with sleeve outer wall installed in the piston rod end of described telescoping cylinder; Described guiding comprises the movable support pin for being horizontally set on the slips of turntable surface and being separately fixed at slips both sides to oral area, each movable support pin is all set with slide block and spring from top to bottom, and slide block can be movable along movable support pin easy on and off, the upper end of described spring and slide block soffit against, lower end and slips upper surface against; On described slide block, be equipped with lateral arrangement and point to the leading screw thimble that overlaps tube hub.
Such scheme is more preferably:
Described telescoping cylinder is three grades of hydraulically extensible cylinders.
Described sleeve pipe hand is semicircle, and its front end is opening shape, and its rear end is connected with the piston rod of telescoping cylinder by bolt, and rear end also can be welded to connect with the piston rod of telescoping cylinder.
Described traversing carriage slide block is bolted on derrick crossbeam.
Described movable support pin is fixed on slips by screwed connection.
The utility model is simple in structure, easy to operate, operating efficiency is high and safety and stability, by the use of casing centering guide, has saved a large amount of time, improves the operating efficiency of make-up, reduces labour intensity, reduces production costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
In figure: 1-treats setting of casing, 2-sleeve pipe hand, 3-one-level telescoping cylinder, 4-secondary telescoping cylinder, tri-grades of telescoping cylinders of 5-, 6-traversing carriage slide block, 7-derrick crossbeam, 8-oil-in, 9-oil-out, 10-slide block, 11-leading screw thimble, 12-spring, 13-slips, 14-movable support pin, 15-well inner sleeve, 16-turntable surface.
The specific embodiment
Referring to Fig. 1, a kind of casing centering guide, comprise that the righting portion on top and the guiding of bottom are to oral area, righting portion comprises by the bolt symmetrical traversing carriage slide block 6 that is movably fixed to 7 liang of sides of a ship of derrick crossbeam respectively, the inner side of traversing carriage slide block 6 is fixing telescoping cylinder (three grades of hydraulically extensible cylinders) that can transversal stretching respectively, which is provided with oil-in 8, oil-out 9, the semicircle sleeve pipe hand 2 that (or welding) and sleeve outer wall coincide is installed by bolt in the piston rod end of telescoping cylinder; Guiding comprises the slips 13 being horizontally set on turntable surface 16 and the movable support pin 14 that is separately fixed at slips 13 both sides to oral area, each movable support pin 14 is all set with slide block 10 and spring 12 from top to bottom, and slide block 10 can be movable along movable support pin 14 easy on and off, the upper end of spring 12 and slide block 10 soffits against, lower end and slips 13 upper surfaces against; On slide block 10, be equipped with lateral arrangement and point to the leading screw thimble 11 that overlaps tube hub.
Operating principle is: when first sleeve pipe sling, first sleeve pipe is put into the female joint of well inner sleeve 15, the remaining 6-8 button of sleeve pipe pin thread, observes sleeve pipe incline direction, use the righting portion adjustment on top to make after casing centralization, then by traversing carriage slide block 6 fixation on derrick crossbeam 7.Then use casing tong slow circumvolve to transfer tourist bus, now slide block 10 can be screwed out with treating that setting of casing 1 moves down when leading screw thimble 11 departs from screw thread, continues rotary sleeve pipe wrench and completes button simultaneously.
Specific works process is: this instrument forms (as shown in the figure) by upper and lower two parts.Superstructure in left and right two sides of a ship install respectively one, traversing carriage slide block 6 makes to be fixed by bolts on derrick crossbeam 7, the hydraulic power source of usage platform is power source, officials are drilled in the work of controlling telescoping cylinder in driller house, the collapsing length of telescoping cylinder is 4.2 meters, regulating afterbody to be fixed on traversing carriage slide block 6 on derrick crossbeam realizes and moving forward and backward, sleeve pipe hand 2 shape semicircular ring, with bolt, be connected with one-level telescoping cylinder 3, rely on different realization of overhang of telescoping cylinder to move left and right, thereby promote sleeve pipe hand 2, carry out righting sleeve pipe.Lower part is divided and is complemented each other with top, movable support pin 14 and slips 13 use screwed connections, on movable support pin 14 between slips 13 and slide block 10, spring 12 is housed, slide block 10 can be movable along movable support pin 14 easy on and off, after sleeve pipe of G.I.H, the unsettled setting of casing 1 for the treatment of of tourist bus, pull leading screw thimble 11 and carry out centering sleeve pipe pin thread, then casing tong low speed rotation, tourist bus is slowly transferred, align the box of well inner sleeve 15, when casing tong is used because out of plumb is subject to self gravitation pulling force backward, the sleeve pipe hand 2 on top and telescoping cylinder (one-level telescoping cylinder 3, secondary telescoping cylinder 4, three grades of telescoping cylinders 5) under the effect of hydraulic power, reduce this pulling force, thereby play the object that makes casing centralization, make make-up and upper button become convenient and swift, when casing job is smooth, substructure can be screwed out from slips, this device volume is little, simple in structure, easy to use.
For those skilled in the art, do not departing under the prerequisite of the utility model principle, likely to concrete size, or partial structurtes make some improvements and modifications, and these improvements and modifications also should be considered as protection domain of the present utility model.
