Abstract
The utility model provides a multi-purpose lifting and unfreezing pipe pulling device which is used for pulling oil pipes and casing pipes during oil field construction matched with well drilling and borehole operation and in oil field abandoned wells. The multi-purpose lifting and unfreezing pipe pulling device is composed of an upper locking and fixing system, a lower locking and lifting system and a hydraulic system, slips are arranged on the upper locking and fixing system and the lower locking and lifting system, the lower locking and lifting system is capable of freely moving vertically along a high-pressure hydraulic cylinder, the moving direction of the lower locking and lifting system is determined by the oil supplying direction of the hydraulic system, an upper slip base is provided with a connecting hole, and the upper slip base is in interference fit and connected with a hydraulic cylinder connecting bar through the connecting hole. The multi-purpose lifting and unfreezing pipe pulling device is simple in structure, flexible and fast in installation, safe in operation, capable of avoiding accidents occurring when a well drilling derrick and a working derrick are used for lifting a big load, low in weight, convenient to transport, and convenient to install. Compared with the traditional one-time pipe pulling method, the repeated pipe pulling method adopted by the multi-purpose lifting and unfreezing pipe pulling device enables the whole system to operate more steadily.
Description
Technical field
The utility model provides a kind of multiplex lifting unfreezing pipe extractor, is applicable to the oil field construction and cooperates choosing of the interior oil pipe of drilling well, underground work and oil field abandoned well, sleeve pipe.
Background technology
By the disclosed a kind of Multifunctional pipe puller of Machinery Factory of Shengli Petroleum Administration, it is comprised of hoisting system, hydraulic system, Hoisting System three parts.Hoisting system is provided with two groups of oil cylinders that diameter is different, and the crossbeam of hoisting system is provided with rotating disk, slips, and the base of hoisting system can move up and down along four righting-oriented posts on the base of ground.
Huge (about 15 tons of the whole full weights of this drawbench integral body, long 9 meters, wide 3 meters, high 2.5 meters), necessary flat seat is on ground, so only adapt to oil pipe, sleeve pipe and protective casing in the abandoned well of oil field choose and also hoisting transportation loaded down with trivial details, when the workover treatment downhole tool is met card or in the wellbore construction process since place and workover rig can not move at the scene etc. former thereby can't in the unfreezing accident, use.This equipment is chosen with can only being applicable to oil field abandoned well interior oil pipe, sleeve pipe and protective casing, and the well that can pull out oil pipe, sleeve pipe and protective casing owing to the oil field abandoned well is less so utilization rate is lower.
The utility model content
For solving the problems of the technologies described above, the utility model provides a kind of simple in structure, easy to operate, reliable multiplex lifting unfreezing pipe extractor of safety.
The utility model is achieved in that
Multiplex lifting unfreezing pipe extractor, comprise the system of being locked, lower locking hoisting system and hydraulic system three parts, on the system that is locked formed by upper slips seat and slips, the upper slips seat is provided with connecting hole, lower locking hoisting system is comprised of lower slips seat and slips, the upper slips seat is connected with the fluid cylinder connecting rod by connecting hole, and lower locking hoisting system is nested on the high pressure fluid cylinder, and can move along high pressure fluid cylinder easy on and off.During work, can transform flange is connected with well head, hydraulic power unit injects the high pressure fluid cylinder with hydraulic oil by in-line 2, lower locking hoisting system moves up, device for cleaning pipeline is crossed rear together the moving up with the lower slips seat of lower locking hoisting system locking and is realized extracting of pipeline, slips in this process in the lower locking hoisting system moves down with respect to the lower slips seat, thereby guarantees the locking state to pipeline, progressively pipeline is extracted; Hydraulic power unit injects the high pressure fluid cylinder with hydraulic oil by in-line 1, lower locking hoisting system moves down, slips wherein moves up with respect to the lower slips seat, unclamp pipeline, slips in the system that is locked simultaneously moves down with respect to the upper slips seat, locking pipe, thus guarantee that pipeline can not glide; This process repeats, and progressively pipeline is extracted.
Further, the upper slips seat is connected by interference fit between connecting hole and the fluid cylinder connecting rod.
The utility model is simple in structure, and is flexible for installation quick, and handling safety avoid Drilling derrick and workover derrick to promote large load and have an accident, and the whole system quality is light, convenient transportation, the convenient installation.Compare with traditional disposable tubing method for pulling out, the utility model adopts repeatedly tube drawing mode, and the whole system running is more steady.
