Abstract
The utility model discloses a pair of pneumatic (hydraulic) slips for petroleum drilling, which is multifunctional and is provided with a righting device. The utility model is connected with a drilling disk of a drilling rig into a whole, and has the functions of clamping a drill column and the hanging load of a sleeve string when the operation of lifting a drill, connecting a well drilling simple root, lowering a sleeve, etc. are carried out; besides, the utility model can transfer the dynamical torque of the disk to clamp a drilling ruler for a square drill rod and can bear an elevator which is heavily loaded. The utility model has the advantages of rapid movement, reliable and safe action and complete exemption to the manual labor of drillers and to slurry sprinkling and is a requisite implement matched with a pair of tongs and the dynamical elevator on the drill rig.
Description
The utility model is the moving slip system of the working gas of a kind of oil drilling (liquid).
The slips that each oil drilling team of existing China generally uses is by the hand-held operation of making a concerted effort of driller.Owing to be in open-air atmosphere during drilling well, the mud spray person is often arranged on the raised platform around a well, the underfooting mire is skidded.Slips is very heavy in addition, and the manual operation slips is the dangerous greatly work of a kind of loss muscle power.
The purpose of this utility model: provide the moving slips of the working gas of a kind of oil drilling (liquid).It is by gas (liquid) press-brake, laborsaving fast and safely reliable without manual operation.
The utility model is achieved in that
Take out the big quadrel in the brill dish on the rig, change the new quadrel of parts that the utility model provides, shown in the miscellaneous part by specification accompanying drawing that the utility model is provided, be installed in brill dish top respectively, and fastening good, can carry out the wellbore construction operation.
Describe concrete structure of the present utility model and assembly method in detail below in conjunction with embodiment.
Accompanying drawing 1 is vertical cross section figure of the present utility model.Accompanying drawing 2 is section plans of the utility model (taking down loam cake part in addition).Please referring to Fig. 1:
Take out the original big quadrel that bores in disk center's through hole, new quadrel (1) changes the outfit; Connect six lobe shape wiper blocks (2), and put it in the interior garden of the epimere awl mouth of new quadrel (1), connect fastening with the turntable upper surface with bolt (13);
With six block pressur plates (5) and six L templates (8), be unified into a roman garden ring with Xiao Zi;
On each L template (8), adorn one pair of connecting rod (7) lower end respectively and connect slips body (9);
The pressing plate that is connected into ring-type together with the slips body be enclosed within lobe shape wiper block around and radially go in the crack; Support (3) is inserted between pressing plate (5) and the lobe shape wiper block (2), and fastening with bolt and lobe shape wiper block, the up and down ring-type pressing plate of trying drives the slips body, and should be able to move up and down does not have the jam phenomenon freely.
Cover loam cake (6) in support (9) upper end; Fix two backplates (4) on the shell body of brill dish, allow the alternate seam of two backplates respectively facing to the weight indicator on the rig and the direction of pipe slacking block;
By dress shift fork (11), its end is stretched in the level trough that snaps into ring-type pressing plate (5) in the seam of backplate.Be twisted together gas (liquid) cylinder and fixed mount of the other end can be started working.
Structure motion principle of the present utility model is: gas (liquid) press-brake piston rod, interlock shift fork (11) moves up and down and drives annular pressing plate (5) and fluctuate, connecting rod on the annular pressing plate (7) is promptly upwards mentioned slips body (9) position as shown in Figure 1 with annular pressing plate, and at this moment the slips body is dispersed in the crack between the lobe shape wiper block; Annular pressing plate is downward, connecting rod (7) promptly promotes to slide under the slips body position of the bottom shade signal of arrow points shown in Figure 1, this moment, the slips body promptly gathered together under the two sections conical surface effect of new quadrel (1), toroidal cavity between wedging drilling rod or sleeve pipe and the quadrel (1), thereby the dental lamina of slips (9) presses tube surface, the wedging dynamic balance that normal pressure that the weight of drilling rod can be produced by the conical surface of six slips bodies (9) and new quadrel (1) and frictional force form is accepted the drilling rod suspending weight.
The slips body is to ensconce six perps of flap wiper block with boring disc spins when creeping into, owing to the centrifugal action that rotates, and the duty that the slips dispersion can not hinder kelly bar.
The effect of flap wiper block (2) is that to guarantee that drilling rod can not depart from garden well center line excessive, slips is moved up and down smoothly, the operating efficiency of assurance slips.
When handling drilling failure, can remove the utility model easily, the former big quadrel of adorning the brill dish again carries out the accident operation.
Implementing the utility model needn't carry out big repacking to the rig of any model, does not also influence the motion state of former rig.Therefore the utility model be applicable to any large, medium and small type oil-well rig in, the deep drilling well construction uses.
Implement the moving slips of the utility model gas (liquid) and have following outstanding advantage:
1, it is packed in and has several functions on the brill disk center turntable of drilling well: rise, lower brill bit change, single drilling depth, the casing job etc. of carrying out of stacks, can block fast drill string or bunch tube, bear suspending weight;
2, owing to adopted the structural design of the two sections conical surfaces, the stroke ratio manual slip that slips moves up and down has shortened 1/3rd, operating rate is fast, chucking is firm, length of action and the area of slips have been increased simultaneously, reduced the pressure on the unit are, the frequency on slips pressing plate damage drilling rod surface greatly reduces;
3, the loam cake configuration design of slips can be by putting master bushing. Can clamp kelly bar when creeping into and throw chi into. Showed the molten prospect that is integrated of slips and brill dish, no heavy physical labour realizes that the possibility of electronic telecontrol possesses on the rig floor;
4, but the bearing lotus has the elevator of drilling tool or bunch tube weight above the loam cake of slips, in the absence of down-hole accident, has exempted the trouble of moving slips fully.
5, without manpower handling slips.Alleviate driller's heavy physical labor and the hardship of exempting the mud spray greatly; Can be supporting with power tongs and the moving elevator of electricity (gas), realize that rig floor does not have heavy physical labour, carry out production strictly in line with rules and regulations.
Claims (1)
- The moving slips of a kind of oil drilling construction usefulness gas (liquid) is characterized in that:Bore be equipped with in disk center's through hole be designed to the garden conical surface in two sections new quadrel 1.; Connect six lobe shape wiper blocks 2., and put it in the awl mouth of the interior garden of new quadrel epimere 1., connect fastening formation drilling rod with the turntable upper surface with bolt ⒀ and set upright parts;8. 5. six block pressur plates be coupled to a whole garden ring with Xiao Zi with six L templates, adorns one pair of connecting rod 7. on each L template, and connecting rod 7. lower end connects the slips STATEMENT OF FEDERALLY SPONSORED that 9. the slips body forms uniqueness;The ring-type pressing plate together with the slips body be enclosed within lobe shape wiper block around and radially in the crack, support 3. be inserted in pressing plate 5. and lobe shape wiper block 2. between and with bolt and the fastening formation loam cake of lobe shape piece support member 6., to accept the drilling tool loading.
