Abstract
The utility model relates to oil field well repairing tools, namely a retractable fishing cylinder which is used for fishing oil tubes, drill pipes, and tubular falling objects with the circular tops of various sizes. The retractable fishing cylinder comprises an upper joint, a cylinder body and a guiding shoe component, wherein the upper joint, the cylinder body and the guiding shoe component are sequentially connected. Two symmetric guiding pins are installed in the middle section of the cylinder body. A spring is installed inside the cylinder body. A guiding sleeve is arranged at the lower end of the spring. An external-hanging slip is arranged at the lower end of the guiding sleeve. The guiding sleeve is provided with an L-type track reversing sliding groove which controls the position of the slip inside the cylinder body. According to the retractable fishing cylinder, no rotating equipment or the well depth exists on the ground, according to an inclined well and a well where rotation of a tool is not easy to control, the whole fishing and releasing process can be completed only by conducting lifting and dropping and then conducting rotating, the lifting process is not required to be carried out along with the rotating process, and the retractable fishing cylinder has the advantages of being simple in structure and flexibly facilitating fishing and releasing.
Description
technical field
The utility model relates to a kind of oil well instrument, can move back dipper.The tops of fish such as oil pipe, drilling rod and tubulose that are used for salvaging various sizes are circular fish.Trade name: L-type can be moved back dipper.
Background technology
In the prior art, when salvaging junk (being commonly called as fish), well workover adopts releasable fishing socket, comprise top connection, the top connection rear portion connects cylindrical shell, and there is fine thread at the cylindrical shell two ends, near back-up ring one end and top connection, links, another termination guide shoe, be processed with the left-handed conical surface screw thread of coarse pitch in cylindrical shell, there is a keyway at the screw thread starting point place of cylindrical shell lower end, is limiting and is milling control ring transmitting torque.Basket slips inwall has the bull buttless thread through quenching, and there is the left-handed conical surface screw thread consistent with cylindrical shell outside, at circumferencial direction, has four uniform vertical long mouthful, and wherein one is elongated opening.At elongated open end, there is wide keyway to coordinate with the key that mills the control ring.Milling control ring end has mill teeth, can be repaired top of fish, and the other end has the key matched with the cartridge openings keyway.Instrument is guide shoe bottom, top of fish can be introduced to instrument.While salvaging fish, fish inserts in slips, and it is descending that while above carrying, fish drives slips, by the sawtooth conical surface, tightened, and carries in continuation and can complete fishing.When fish is blocked when tighter, can discharge fish by the rotation tubing string in vertical shaft, exit tubing string.Its shortcoming is complex structure, discharges fish dumb.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure for above-mentioned deficiency, salvages and discharges flexible moved back dipper.
Technical solution of the present utility model is: can move back dipper and comprise top connection, cylindrical shell, the guide shoe parts that connect in turn.The cylindrical shell interlude is equipped with two symmetrical guide fingers, and spring is housed in cylindrical shell, and lower end is fairlead, the plug-in slips in fairlead lower end, and fairlead, with the track commutation chute of L-type, is controlled slips position in cylindrical shell.
The utility model has the advantages that: this dipper is to ground without rotating machinery and well depth, and inclined shaft rotates uppity well to instrument, only needs to put to put the overall process that rear rotation can complete salvaging and discharge.Without Shang Ti limit, limit, revolve.Have simple in structurely, salvage and discharge flexible characteristics.
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is the utility model structure diagram.
Fig. 2 is the track commutation chute partial view of L-type.
The specific embodiment
Referring to Fig. 1,2, the component title is as follows: top connection 1, cylindrical shell 2, guide shoe 3, guide finger 4, spring 5, fairlead 6, slips 7, the track commutation chute 8 of L-type.
Referring to Fig. 1, can move back dipper top connection 1 upper end the box thread be connected with drilling rod is arranged, there is the angular thread be connected with cylindrical shell 2 lower end, cylindrical shell 2 lower end external diameters have the angular thread be connected with guide shoe 3, cylindrical shell 2 interludes are equipped with two symmetrical guide fingers 4, spring 5 is housed in cylindrical shell 2, and lower end is fairlead 6, connecting thread shape guide shoe 3 under fairlead 6 plug-in slips 7 cylindrical shells in lower end.
Referring to Fig. 1,2, fairlead 6, with the track commutation chute 8 of L-type, by moving up and down, and then rotates, and controls slips 7 in the interior position of cylindrical shell 2.After transferring dipper introducing fish, upper bailer, make dipper slips 7 in the salvaging state, and upper bailer fish tubing string is tightly bitten, if after transferring dipper, rotation can be exited fish again.
Method of operating
1, select the dipper of appropriate size according to the fish diameter, and slips 7 is put into to off-position, then be tightened on drill string.
2, transfer instrument, when instrument approaches top of fish, the lowering velocity that should slow down, introduce fish, observes weight indicator and go up, and stops transferring.
3, carry instrument on, afterburning wanting evenly, and, according to the situation of change of weight indicator, determine whether engagement with the fish, if there be not engagement with the fish again transfer instrument, carry on again.When pulling force rises to the instrument maximum load, still fish can't be proposed, answer the turn on pump cyclic flusher.
4, when tripping out while meeting the card fish, need to discharge fish and propose instrument, percussion tool downwards still, then 90 ° of slow circumvolves can make tool and exit, and once do not become, and can repeat, until exit fish.
Claims (1)
1. one kind can be moved back dipper; comprise the top connection (1), cylindrical shell (2), guide shoe (3) parts that connect in turn; it is characterized in that cylindrical shell (2) interlude is equipped with two symmetrical guide fingers (4); spring (5) is housed in cylindrical shell (2); lower end is fairlead (6); the plug-in slips in fairlead (6) lower end (7), fairlead (6), with the track commutation chute (8) of L-type, is controlled slips (7) position in cylindrical shell (2).
