Description
Technical field
The utility model relates to a kind of oil field band and presses well repairing device.
Background technology
At present, in China during to the oil in oil field, gas, well upkeep operation, if in the well pressure is arranged, usually adopt open flow and kill-job dual mode that borehole pressure is discharged, carry out workover treatment then, its shortcoming is that open flow causes the loss of stratum energy and environment is polluted, and the open flow time is long, causes well workover efficient low; Kill-job then causes the destruction on stratum and pollution.
The utility model content
The technical problems to be solved in the utility model is at above-mentioned deficiency, provides a kind of oil field band to press well repairing device, utilizes this device, has at oil well under the situation of pressure, does not need open flow and kill-job just can carry out workover treatment.
In order to solve the problems of the technologies described above, the utility model provides a kind of oil field band of following structure to press well repairing device, comprise carrier, the bottom of carrier is connected with Height Adjustable support, the bottom of carrier is connected with loaded plate, loaded plate is provided with the oil pipe passage, be connected with preventer on the soffit of loaded plate, be connected with on the preventer and be used for the wellhead flange that is connected with well head, be connected with down fixedly pipe clamping device on the upper surface of loaded plate, preventer is with fixedly the inner chamber of pipe clamping device is corresponding with the oil pipe passage down; Down fixedly be connected with the box cupling alarm on the pipe clamping device, be serially connected with down successively from bottom to top on the following fixedly pipe clamping device belt preventer, tube connector, upward belt preventer, on fixedly pipe clamping device and high pressure are self-styled, be connected to pressure release valve on the tube connector; The both sides of loaded plate respectively are connected with oil cylinder, be connected with the lifting crossbeam on the piston rod of oil cylinder, the lifting crossbeam is provided with the oil pipe via hole, top and following the move about pipe clamping device and the slips rotating mechanism of being connected with respectively of lifting crossbeam, the inner chamber of pipe clamping device and slips rotating mechanism of moving about is corresponding with the oil pipe via hole, and this device also comprises control system.
Described slips rotating mechanism comprises with the affixed fixed cover of lifting crossbeam and is screwed onto movable sleeve on the fixed cover, is bolted with the leading screw that is used to clamp oil pipe on the movable sleeve.
The oil field band of said structure presses the use of well repairing device as follows: at first press the oil field band well repairing device to place the top of oil well, the height of adjusting the support of carrier bottom then is tightly connected wellhead flange and well head.In the time need from oil well, proposing the oil pipe in the oil well to change or repair, guide the connection of oil pipe earlier, promptly earlier an Oil-saving pipe is connected with oil pipe in the oil well with this device.The connection of guiding oil pipe is achieved in that by the control system driving oil cylinder rises, the guiding oil pipe is pierced into the pipe clamping device and it is passed of moving about from the slips rotating mechanism, start the pipe clamping device that moves about and block the guiding oil pipe, and then descend by the control system driving oil cylinder, pierce into successively in the process that the guiding oil pipe descends with oil cylinder high pressure self-styled, on fixedly pipe clamping device, upward go in ring preventer, tube connector, down belt preventer, fixedly pipe clamping device and preventer and oil pipe final and in the oil well dock down; If oil cylinder drops to low level time guiding oil pipe does not still dock with oil pipe in the oil well, starting upward this moment fixedly, pipe clamping device blocks the guiding oil pipe and makes the pipe clamping device that moves about unclamp the guiding oil pipe, starting oil cylinder then makes it to rise, after oil cylinder rises to certain altitude, make the pipe clamping device that moves about block the guiding oil pipe again and make fixedly that pipe clamping device unclamps, then make oil cylinder drive the guiding oil pipe and descend, move about like this pipe clamping device and the alternation of last fixedly pipe clamping device are docked with oil pipe in the oil well until the guiding oil pipe; The guiding oil pipe is with after oil pipe in the oil well docks, clamping move about pipe clamping device and last fixedly pipe clamping device of guiding oil pipe and making with the slips rotating mechanism unclamps, clamp the guiding oil pipe with Power Tong then, the rotational power pincers make in the screw thread of the box cupling of oil pipe in the guiding tube precession oil well, and the connection of guiding oil pipe has just been finished.After the connection of guiding oil pipe is finished, block the guiding oil pipe and unclamp the slips rotating mechanism with the pipe clamping device that moves about, start oil cylinder and drive move about pipe clamping device and the rising of guiding oil pipe, when oil cylinder rises to extreme position, use fixedly pipe clamping device chucking guiding oil pipe, the pipe clamping device that moves about unclamps and drops to behind the low level chucking guiding oil pipe again with oil cylinder, unclamp fixedly pipe clamping device and oil cylinder is risen once more this moment, after the guiding oil pipe is thus lifted to assigned address, it is screwed off, and then utilize the alternation of move about pipe clamping device and last fixedly pipe clamping device, just can propose the oil pipe in the oil well one successively, oil pipe proposes the back just can be to the oil well repairing of being correlated with.In above-mentioned oil pipe proposition process, when approaching time belt preventer of tubing coupling, the box cupling alarm sends signal, belt preventer is opened and the preventer that goes in ring is cut out by control system, after belt preventer is passed down in tubing coupling, again by belt preventer cutting out and the preventer that goes in ring is opened, the alternation by go in ring down preventer and last belt preventer realizes from the well inner high voltage to the conversion of normal pressure overseas.Down the purpose that alternately opens and closes of belt preventer and last belt preventer is to realize the conversion from the well inner high voltage to normal pressure overseas and cross box cupling, box cupling is through following belt preventer or go up when going in ring preventer, the corresponding preventer that goes in ring will be opened, the purpose of opening is the seal that prevents the belt preventer of box cupling damage, guarantees the durability of seal.The effect of preventer is to utilize its corresponding valve plate to cooperate with oil pipe so that shunt in a well after shunt in a well in the oil pipe lifting process blowout prevention and the whole propositions of oil pipe.High pressure is self-styled to be general sealing when being used for carrying on the oil pipe or transferring.Pressure release valve be used for the tube connector internal pressure when high to its pressure release.Following fixing pipe clamping device standby as last fixedly pipe clamping device, oil pipe are when fixedly pipe clamping device is not easy to tighten oil pipe on specific position, and can utilizing down fixedly, pipe clamping device tightens oil pipe.Oil pipe proposes process as mentioned above, and the process of transferring of oil pipe is opposite with the operating sequence that oil pipe proposes, and concrete operations do not repeat them here referring to the top description that the guiding oil pipe is connected.
From above-mentioned description, be not difficult to draw to use, oil field provided by the utility model band is pressed well repairing device, have at oil well and have under the situation of pressure, do not need open flow and kill-job just can carry out the advantage of workover treatment, brought energy conservation thus, prevent to pollute, save the beneficial effect of activity duration.
