Abstract
The invention discloses a work-over elevator rotor, which is characterized in that an elevator is mounted on an oil pumping pipe 1; an elevator 6 is mounted on a rotor 7 which is composed of an oil pumping line 4, a heavy-load-bearing cap 3, a rolling bearing 4 and a locking screw nut 5; the rolling bearing 4 and the locking screw nut are both mounted on the oil pumping line 1; the oil pumping line 1 and the rolling bearing 4 are positioned in the heavy-load-bearing cap 3; the locking screw nut 5 is positioned below the heavy-load-bearing 3. The invention has the advantages of simple structure, convenient usage and low maintenance cost.
Description
Technical field
The present invention relates to the power tool that the well workover of a kind of oil field is used, particularly a kind of well workover elevator rotor device, the supporting use of hydraulic tongs that main and oil field well workover is used can directly be used for drilling the filler (as the concrete obstruction) in the well, or drills the construction operation of bridging plug etc.
Background technology
When oil is got in well-digging in the oil field, when the down-hole does not have oil, often this layer well sealed, form " cement plug ", in practice with concrete, owing to reasons such as ground qualitative responses, have oil often after a period of time below " cement plug " again and occur, therefore, if want to continue to obtain " cement plug " following oil, just " cement plug " must be drilled, to extract the oil of lower floor.At present, in being engaged in the construction operation that drills " cement plug " and bridging plug, mainly be to use screw pump, employed medium had relatively high expectations, easily make screw pump problems such as obstruction occur, brought trouble to construction, and maintenance cost is higher because of it; In addition, it is strict, careless slightly to use screw pump that operating personnel are required, and just is easy to cause bit freezing, makes into well oil pipe back-off to come off, and need repeatedly salvage oil pipe, and seriously having influenced recovers the oil produces.
Summary of the invention
The objective of the invention is to want to overcome above-mentioned the deficiencies in the prior art, the construction tool-elevator rotor device that provides a kind of new oil field well workover to use, this elevator rotor device is simple in structure, easy to use, and maintenance cost is low.
For realizing that the technical scheme that above-mentioned purpose of the present invention adopts is: a kind of elevator rotor equipment for repairing well, its design feature is that an elevator is installed on oil pick-up tube, rotor is housed on the elevator, rotor is to be made of oil pick-up tube, load-bearing pressure cap, rolling bearing and locking nut, rolling bearing and locking nut all are installed on the oil pick-up tube, oil pick-up tube and rolling bearing are positioned at the load-bearing pressure cap, and locking nut is positioned at the bottom of load-bearing pressure cap.
For preventing that lubrication oil from leaking, all establish joint ring at the upper and lower side of rolling bearing, filling sealing material in the joint ring.
The present invention only installs elevator and rotor on oil pick-up tube, it is simple in structure, during use, on the oil pick-up tube that the oil pick-up tube bottom is connected in the correcting device of oil field with drill bit links to each other, top is connected on the hose by curved neck, and the power by hydraulic tongs drives oil pick-up tube and rotates, oil pick-up tube drives drill bit and rotates, easy to use, compared with prior art, it neither needs particular medium, do not need specific operating personnel yet, operation is simple, and breakdown rate is low, and maintenance cost is low.
Description of drawings
The structural representation of Fig. 1 embodiment of the invention
Fig. 2 is a user mode structural representation of the present invention.
The specific embodiment
Below in conjunction with specific embodiment the present invention is done further detailed description.
As seen from Figure 1, the present invention installs an elevator 6 in oil pick-up tube 1, one rotor 7 is installed on the elevator 6, rotor 7 is to be made of oil pick-up tube 1, load-bearing pressure cap 3, rolling bearing 4 and locking nut 5, rolling bearing 4 and locking nut 5 all are installed on the oil pick-up tube 1, oil pick-up tube 1 and rolling bearing 4 all are positioned at load-bearing pressure cap 3, and locking nut 5 is positioned at the bottom of load-bearing pressure cap 3.Upper and lower end at rolling bearing 4 is equipped with joint ring 2, is filled with the sealing material in the joint ring.
When the present invention uses, oil pick-up tube 1 bottom is connected on the oil pick-up tube 9 that links to each other with drill bit 11 in the correcting device of oil field by nut 8, top is connected on the hose 13 by curved neck 12, drive whole oil pick-up tube by the power that is stuck in the hydraulic tongs 10 on the oil pick-up tube 9 and rotate, oil pick-up tube and then drive drill bit rotate.
