Description
Technical field
The utility model relates to a kind of rod-pumped well, screw bolt well construction operation field, is applicable to the unfreezing construction that rod-pumped well, screw bolt well roofbolt are stuck, specifically a kind of back-off device of sucker rod.
Background technology
During oil well production, often occur that the reasons such as sand card, wax card, junk cause holddown phenomenon, thus carry out the construction of inspection pump, well head is not torn open when playing bar in construction, cause rod elevator because ultralimit large-tonnage pulls out sucker rod or hang that cylinder damages, sucker rod pulled off, sucker rod makes full well sucker rod can not use and scrap after carrying on large load; It is on-the-spot when the mode of well head rod tube synchronization onwards is torn in employing open, because rod tube length is inconsistent, cannot sucker rod be laid down and be forced to sucker rod sawed-off, sucker rod is extracted out again in oil pipe, to waste time and energy and dangerous, simultaneously a large amount of sucker rod is by sawed-off and scrap, and sting with 48 inch pipe wrench and carry out back-off in the manual type of the body of rod, easily the very large bounce of generation causes casualty accident.There is many hidden dangers in holddown well construction, in order to the development back-off device of sucker rod that solves the problem.
Utility model content
For solving Problems existing in background technology, the utility model proposes a kind of back-off device of sucker rod, both the generation of peril had been avoided, turn avoid rod elevator, hang the damage of cylinder, reduce the loss of sucker rod, reduce operating cost expense, alleviate the labour intensity of operation work, improve efficiency of construction.
The technical solution of the utility model is: a kind of back-off device of sucker rod, comprise lifting sub, back-off device of sucker rod main body, power transmission pipe nipple, lifting sub is connected with street corner on pressure cap connector, the lower contact of pressure cap connector is connected with the top connection of reverse buckling equipment main body, the lower contact of reverse buckling equipment main body is connected with power transmission pipe nipple, wherein, being also provided with cone slips and steady key in described reverse buckling equipment, cone slips being provided with the horizontal tooth for stinging tight sucker rod and perpendicular tooth;
Described slips is centrum, is provided with coordinates inclined-plane with centrum slips in reverse buckling equipment body interior;
Described slips is welded with steady key, coordinates with the keyway that reverse buckling equipment main body is arranged.
Beneficial effect is: by the technical scheme adopting the utility model to adopt, both avoided the generation of peril, and turn avoid rod elevator, hung the damage of cylinder, reduce the loss of sucker rod, reduce operating cost expense, alleviate the labour intensity of operation work, improve efficiency of construction.
Accompanying drawing explanation
Fig. 1 is the utility model organigram.
In figure, 1-lifting sub, 2-pressure cap connector, 3-cone slips and steady key, 4-reverse buckling equipment main body, 5-power transmission pipe nipple.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further.
A kind of back-off device of sucker rod as shown in Figure 1, a kind of back-off device of sucker rod, comprise lifting sub 1, back-off device of sucker rod main body 4, power transmission pipe nipple 5, lifting sub 1 is connected with pressure cap connector 2 top connection, pressure cap connector 2 lower contact is connected with reverse buckling equipment main body 4 top connection, reverse buckling equipment main body 4 lower contact is connected with power transmission pipe nipple 5, wherein, cone slips 3 is also provided with in described reverse buckling equipment, cone slips 3 is provided with and tight sucker rod carries non-slip horizontal tooth for stinging and sting the non-slip perpendicular tooth of tight inversive fastening pumping rods, after cone slips 3 runs locking sucker rod in reverse buckling equipment main body 4, horizontal tooth plays the effect of skidding when preventing from proposing, perpendicular tooth plays the effect preventing reverse buckling equipment along sucker rod skidding axial rotation.
Described slips 3 is centrum, is provided with coordinates inclined-plane with centrum slips 3 in reverse buckling equipment main body 4 inside, is convenient to install cone slips, be also convenient to cone slips 3 at reverse buckling equipment main body 4 internal operation and lock watt.
Described slips 3 is welded with steady key, coordinates with the keyway that reverse buckling equipment main body 4 is arranged, prevent when inversive fastening pumping rods cone slips 3 from skidding in reverse buckling equipment main body 4 inside.
Concrete, when oil well generation sand card, wax card, when the reasons such as junk cause holddown problem, transfer hook and back-off device of sucker rod sucker rod is motionless, now fix hydraulic tongs and tail rope, lifting sub 1 and pressure cap connector 2 top connection are connected tight, power transmission pipe nipple 5 and back-off device of sucker rod main body 4 lower contact are connected tight, again pressure cap connector 2 lower contact and back-off device of sucker rod main body 4 top connection are connected tightly, 21/2 pipe elevator is buckled on 1 lifting sub, with hook being carried back-off device of sucker rod to sucker rod upper end, sucker rod is poured in back-off device of sucker rod main body 4, transfer hook to power transmission pipe nipple 5 lower end close to plane on well head, pressure cap connector 2 lower contact and back-off device of sucker rod main body 4 top connection are unclamped, the sucker rod cone slips 3 selected and match in well loads in back-off device of sucker rod main body 4, screw gland, back-off device of sucker rod is carried repeatedly, select to open chalaza and tonnage in sucker rod, if wax khaki wax deposition point generally carries 1.5 tons on about 400 meters, if junk card is stuck in piston place generally carry 3 tons on about 900 meters, cone slips 3 is carried in process with under sucker rod Action of Gravity Field on back-off device of sucker rod, move down along back-off device of sucker rod main body 4 inclined-plane and the body of rod is tightly bitten, the horizontal tooth of cone slips 3 plays the effect of stinging tight sucker rod, cone slips 3 erects tooth and plays the effect of stinging tight inversive fastening pumping rods, primer fluid pressing tongs is engaged in power transmission short circuit 5 counterclockwise, and rotate until the sucker rod be stuck in oil pipe is opened.
