Description

Hydraulic rotor device

Technical field

The utility model relates to the power tool that the well workover of a kind of oil field is used, the hydraulic rotor device that particularly a kind of well workover is used, it can directly be used for drilling the filler (as the concrete obstruction) in the well, or is used for plugging operations that well casing leaks outside and the construction operation that drills 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 to use screw pump that operating personnel are required, careless slightly, just be easy to cause bit freezing, make into well oil pipe back-off and come off, need repeatedly salvage oil pipe, seriously having influenced and recover the oil having produced, being head it off, disclosing a kind of patent No. in the prior art and be 200620170450.6 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, and rotor is by oil pick-up tube, the load-bearing pressure cap, rolling bearing and locking nut constitute, and 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.This elevator rotor equipment for repairing well, adopt screw pump to drill the defective that the filler in the well exists though solved, but could work because of it must rely on the power of external power-hydraulic tongs, thereby not only use inconvenience, and be that oil well repairing operation institute is unallowed.

Summary of the invention

The purpose of this utility model is to want to overcome above-mentioned the deficiencies in the prior art, construction tool-the hydraulic rotor device that provides a kind of new oil field well workover to use, this hydraulic rotor device utilizes self power can be engaged in work, and is easy to use, meets the needs of present oil field well-repairing work.

For realizing that the technical scheme that above-mentioned purpose of the present utility model adopts is: a kind of hydraulic rotor device, its design feature is that a gear-box is installed on an axle, be provided with flange above the gear-box, two sides all are provided with hanging hook about upper gear case, on the axle in gear-box, be equipped with, lower bearing, by dynamic bevel gear, drive bevel gear, upper bearing (metal) is installed on the top of gear-box inner axis of heart, be installed at the middle part of axle by dynamic bevel gear, be provided with spacer sleeve and lock nut at upper bearing (metal) and between by dynamic bevel gear, hydraulic motor is fixed on the outer wall of gear-box, drive bevel gear is installed on the hydraulic motor, it be installed in axle on matched by dynamic bevel gear, lower bearing is installed on the bottom of the axle in the gear-box, in the bottom of gear-box bearing gland is housed also.

Most preferred embodiment of the present utility model is for being provided with 0 type circle between flange and gear-box.

The utility model is equipped with gear-box on axle, on the gear-box outer wall hydraulic motor is installed, drive bevel gear is housed and by dynamic bevel gear in the gear-box, drive bevel gear is installed on the hydraulic motor, during hydraulic motor work, can drive drive bevel gear and rotate, the drive bevel gear drive is with matching is rotated by dynamic bevel gear, and then drives the axle rotation.During use, on the oil pipe that the axle bottom is connected in the correcting device of oil field with drill bit links to each other, the hole on top is connected on the hose by curved neck, and the power by hydraulic motor drives axle and rotates, and then drive drill bit again and rotate, easy to use, compared with prior art, utilize self power can carry out work, neither need particular medium, also do not need specific operating personnel, operation is simple, meets the needs of present oil field well-repairing work.
