Description

A kind of producing well disc type air operated slips
Technical field
Patent of the present invention relates to that a kind of producing well rises, lower oil pipe operation time automatically hold that the well head automation tools, particularly a kind of long-range pneumatically-operated dependence disc type slip spider and vertical active cylinder of oil pipe drive for rising, lower oil pipe operation time automatically hold the producing well disc type air operated slips of oil pipe.
Background technology
The oil pipe in well is needed to take out one by one time oil well underground work (workover treatment), existing producing well rises, lower oil pipe operation mostly adopts two elevator operating type, namely tubing coupling position is held in an elevator, or be held in tubing coupling with upper/lower positions with slip-type elevator, then promote or decline oil pipe, until needs access or when dismantling next root oil pipe, need to hold next root oil pipe with another elevator or slip-type elevator are outstanding, analogize in proper order and frequently change that elevator has carried out, lower tubing manipulation.There is the problems such as labor strength is large, inefficiency, poor safety performance in this construction operation mode, if two suspension ring hanging elevator when particularly workman frequently changes elevator wherein have one not hang up properly, and driller does not find the words i.e. maloperation being carried oil pipe, single-suspender rig down is easily caused to cause the percussion drill accident of the whole oil pipe in down-hole, cause pipe column falling well, there is great engineering equipment and personal injury hidden danger.
For above problem, Chinese patent: Multipurpose pipe column pneumatic slips (CN200820223023.9) discloses a kind of hollow body slip spider utilizing reinforcing rib to fix and adds the slips body acting in conjunction of torsion spring control to hold the air operated slips of tubing string weight, and Chinese patent: Combined pneumatic slip for oil well operation (CN200520105076), multi-functional rod tube air operated slips (CN201020519940.9), the patents such as a kind of drill collar casing air operated slips (CN201020519977.1) of anti-torsion and Multifunctional well drilling pipe column air operated slip (CN201120039748.4) are all designed with the slip spider and slips body that coordinate different Rotary table for drilling machine size, although remote control pneumatic slips clamping can be realized or unclamp petroleum pipe column, but these patent structures are complicated, guide peg mechanism is all adopted to add the complexity of air operated slips, and bulkyly cannot be installed to well head, undersized oil pipe is held when can not be used for producing well light maintenance operation.In addition, Chinese invention patent: the disclosed a kind of drilling rod by two symmetrical slip spiders and two symmetrical semicircle appending disks and multiple slips body structure of a kind of air spider (CN103132928A) holds instrument, there is complex structure equally, guide peg and cylinder are arranged on the inner inconvenient maintenance of slip spider, and slip spider size needs to coincide with Rotary table for drilling machine size the problem such as could to install.And for example Chinese patent: a kind of air spider for workover treatment (CN2375761Y) discloses a kind of oil pipe pneumatic chuck being fixed on production wellhead be made up of chuck assembly and cylinder assembly, because cylinder assembly is non-standard cylinder, complex structure, working depth is too high thus do not promoted the use of on a large scale.And for example Chinese patent: the Pneumatic oil pipe clamping device of oil well is repaiied in the disclosed a kind of oil field of Pneumatic oil pipe clamping device (2109436U), use more a kind of oil pipe pneumatic slips both at home and abroad, be made up of base portion, gripping part and pneumatic part, the three lobe slips bodies utilizing lever principle to adopt a cylinder to stir gripping part move up and down, in order to clamp or to unclamp oil pipe, instead of the use of well head elevator or slip-type elevator, achieve the working procedure that single elevator adds air spider lower oil tube.But, this pneumatic chucking device due to its base portion be plane structure, need special installation wellhead platform putting equipment, the oil well of operating platform is not had to use to most of light maintenance operation, and the slips body utilizing lever principle to realize lifting motive force is less, reliably effectively oil pipe cannot be clamped when well head deflection is serious, there is the situation that oil pipe glides, the well depth of current producing well is more and more darker, tubing weight is also more and more heavier, needs comparatively large power placed in the middle oil pipe must be pushed into well head center and the problem of reliable clamping during clamping oil pipe urgently to be resolved hurrily.
Summary of the invention
The object of the present invention is to provide a kind of producing well disc type air operated slips, monolithic lifting is fixedly mounted on well head center, the multiple vertical cylinder effect of operated from a distance realizes the lifting action of slips body, has comparatively large power placed in the middle and effectively can clamp and hang and hold tubing weight and have automatic scraping wet goods function when hoisting oil pipe simultaneously concurrently.
The present invention primarily of disc type slip spider (1), slips body (2), cylinder (3), supporting disk (4), connecting rod piece (5), upper pin (6), lower bearing pin (7), scrape oil tray (8), oil wiper (9), centering ring (10) composition, wherein, disc type slip spider (1) is an overall structure, or connect for overall structure by a switching door (11) by slips pin (12), slips body (2) and slip spider (1) also can be slided up and down relatively by measure-alike Inner arc taper-face contact, cylinder (3) to be fixed on slip spider (1) periphery flange and to attach gas channels and can control by remote switch, the piston rod of cylinder (3) is fixed on supporting disk (4), slips body (2) is connected with lower bearing pin (7) and passes through connecting rod piece (5) and is connected with the upper pin be fixed on supporting disk (4), scrape oil tray (8) link with supporting disk (4) and oil wiper (9) is installed betwixt, centering ring (10) is arranged on middle position, slip spider (1) bottom.
Beneficial effect of the present invention is: a kind of producing well disc type air operated slips is intended to solve that existing air spider exists installs and uses inconvenience, a difficult problem that clamping oil pipe power placed in the middle is little, adopt overall disc type slip spider structure first, pithead position is fixed on by wellhead flange, the cylinders of three to four vertical effects are utilized directly to promote three to the up and down clamping of pintongs slips body or unclamp oil pipe, there is power placed in the middle large, the features such as clamping is reliable, easy to install.Both the problem that existing air spider volume is large, install inconvenience had been overcome, also solve that air spider power placed in the middle is little, clamping oil pipe insecure problem, by driller's operated from a distance pneumatic operated valve, the mode of air operated slips cooperation lower oil tube is added by single elevator, greatly reduce labor strength, improve lower oil tube operating efficiency, improve well head safe operating characteristics, ensure personal safety and the device security of the operation of lower oil tube tubing string, ensure that construction operation carries out smoothly.
