Abstract
The utility model provides a new compound type pneumatic clip for the disassembly of a drill pipe, a drill collar, a casing, and an oil tube in a project of petroleum drilling and well maintenance. In specific, the utility model disclosing a compound type pneumatic clip of well construction is characterized in that: the device has a main square clip, a clip series connected with the main square clip, four power cylinder blocks and a pneumatic pipeline assembly are connected to the main square clip, the clip teeth are arranged on the inner side of the clip series, and a mud scrapper assembly is connected with a shaft of the pneumatic clip. The utility model is driven by compressed air, the force exerted on every clip is more equality distributed, thus avoiding operational failures caused by pipe eccentricity. Operation procedure is simpler by replacing the clip to disassemble different pipes than replacing a whole pneumatic clip. Lengthened rectangle clip teeth structure is adopted in the utility model, which enlarges the force bearing area and reduces the possibility of a clip trace while prolongs fatigue life.
Description
Technical field
The utility model removes a kind of well head gripping mechanism of drilling rod, drill collar, sleeve pipe and oil pipe when relating to a kind of oil drilling and workover treatment, particularly a kind of is power with compressed air, has to realize plurality of specifications slips body combination that multiple down-hole string is used and the air operated slips that conveniently exchanges.
Background technology
The gripping mechanism that uses during oil drilling and workover treatment at present is that two elevators or single elevator add portable slips, adopt manually-operated, working strength of workers is big, inefficiency, and existence causes single-suspender rig down initiation engineering accident, hidden danger such as the threat person, device security easily.
At the problems referred to above, the air operated slips that Chinese patent: 03221040.X " oil tubing string air operated slips " and 200320100403.0 " multi-functional full-automatic drilling rod air operated slips " provide wellbore construction to use respectively, it is simple to operate that drilling rod is removed, improve automaticity, reduced working strength of workers.Similar products like is abroad also arranged.But above several air operated slips all adopts single cylinder or two cylinder to promote 4 slips bodies, between the slips body is to connect by guide peg, and eccentric if aboveground tubing string occurs, cisco unity malfunction unbalance stress will appear and in the slips body; Above-mentioned several air operated slips all are the drilling rods of the corresponding a kind of specification of a certain model, and the frequent intersection that removes of drill collar, drilling rod and sleeve pipe is carried out during aboveground operation, just must change different slips when removing different tubing strings, and very trouble operates; The slip insert of air operated slips is a triangular form at present, is stuck on the drilling rod and can produces the card trace, causes descend the application life of drilling rod, and just because of existing the problems referred to above, air operated slips is not applied at home widely.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of novel combination type oil well air operated slips that operation is used is provided, the slips body that it is characterized in that air operated slips inside is to be combined by a slips body that overlaps different size series, when removing different tubing strings, only need to change the slips body, needn't the integral replacing air operated slips, simplified operation sequence, the air operated slips of different size needn't be prepared by each operation troop simultaneously, has reduced operating cost.
The utility model purpose is to overcome the deficiency of existing air operated slips unbalance stress, there are 4 actuating cylinders the air operated slips inside that the novel combination type oil well operation that is provided is used, promote 4 slips bodies and move simultaneously, make stressed more evenly, avoided because the operate miss that tubing string off-centre is caused.
The air operated slips that novel combination type oil well provided by the utility model operation is used adopts rectangle slips dental structure, and increased the length of slip insert, increase lifting surface area, alleviated the tendency that on tubing string, produces the card trace, avoided the negatively influencing of bringing for the drill string life-span.
Particularly, the utility model discloses a kind of combined type oil well operation air operated slips, it is characterized in that comprising: big quadrel; The slips series that links to each other with big quadrel; Be connected to 4 actuating cylinders and pneumatic pipeline assembly on the big quadrel; Be positioned at the slip insert on the slips series inboard; And be connected to and scrape the mud assembly on the axle of air operated slips.
The purpose of this utility model is to realize like this.
The novel combination type oil well operation air operated slips of forming by big quadrel, serial slips body, 4 actuating cylinders and the supporting gentle pipeline of ready-packaged joint, have 4 actuating cylinders, be connected 4 slips bodies with 4 righting rod together support, make the slips body stressed more even, avoided because the operate miss that tubing string off-centre is caused; The slips body that only needs when removing different tubing strings to change different size series gets final product, and needn't the integral replacing air operated slips; What install on the slips body is rectangle slips dental structure, and has increased the length of slip insert, has increased lifting surface area, has alleviated the tendency that produces the card trace on tubing string, has prolonged fatigue life; Big quadrel, slips body, actuating cylinder, scrape parts such as mud assembly, gas circuit pipeline assembly and slip insert and be combination skid-mounted type structure, be convenient to on-site maintenance and change highly versatile.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Among the embodiment as shown in Figure 1, middle tubing string is drilling rod, drill collar, sleeve pipe or oil pipe, and tubing string can pass through by easy on and off in the slips releasing orientation.The utility model mainly by big quadrel (1), slips series (2), 4 actuating cylinders (3), pneumatic pipeline assembly (4), slip insert (5), scrape mud assembly (6), guiding device (7), erection device (8) etc. and form.
After the air inlet of actuating cylinder top, drive gripper shoe and drive the descending and chucking tubing string of slips body, the driving force of four cylinders is enough to tubing string is passed placed in the middle, has overcome hole deviation and has caused the drawback that can't tighten roofbolt.
The utility model is applicable to the rig brill dish of any kinds such as 175,205,275,375, can be used for holding " 3 , 5 ", 5 the drilling rod and 6 of serial size " etc. ", 7 drill collar and 7 of different size " etc. ", 9 " etc. roofbolt and tubing strings such as serial sleeve pipe, the fabricated structure of particular design helps on-site maintenance and replacing.
