Abstract
A slip type rotary oil drain device for a pumping well comprises a coupling, an inner pipe, a blocking joint, a supporting shell, slips, a slope block, a screw, an upper release joint, a lower release joint, an oil drain joint and a sealing ring. When oil drainage is needed in operation, the oil pipe is lifted on the ground, so that the key at the lower part of the upper release joint is embedded with the key at the upper part of the lower release joint, and the torque of the oil pipe is rotated on the ground to enable the connecting threads of the lower release joint and the oil drainage joint to be broken off, so that oil drainage of the oil drainage hole is exposed. Before oil drainage, the oil drainer can not be actuated by various operation operations, so that the slip-type rotary oil drainer has reliable work and high success rate of operation.
Description
The utility model is the pumpingh well slip-type rotation bleeder in the oil exploitation.
Existing bleeder kind is a lot, and great majority are to use in the well that sucker rod is opened draining or the ground drop-in tool is opened draining.If behind the bleeder rod parting of these types, sucker rod is carried to be come out, can't realize draining.
The purpose of this utility model is to avoid the deficiency of existing bleeder, and a kind of slip-type rotation bleeder is provided, and realizes the draining of opening of bleeder by rotation pipeline, solves because of the disconnected problem that can not draining of sucker rod.
The purpose of this utility model be achieved in that it by box cupling, interior pipe, retaining joint, support housing, slips, sloping piece, screw, go up releasing-joint, releasing-joint, draining joint, sealing ring are formed down.Interior pipe is connected under the box cupling, and the outside of interior pipe is respectively retaining joint, support housing, slips, sloping piece, screw from top to bottom, goes up releasing-joint, following releasing-joint, and interior pipe bottom connects the draining joint.Pipe was outside in last releasing-joint was set in, last releasing-joint top connects with the retaining joint, support housing is sleeved on the releasing-joint outside and is under the retaining joint, have four windows on the support housing, sloping piece and slips are installed by Dui Ying two window places respectively, slope piece inwall contact is on last releasing-joint external surface, the circular arc of slope piece inner surface does not overlap with the center of circle of the circular arc of external surface, the slope piece is screwed on last releasing-joint, the bottom of last releasing-joint has processed the key of opening, and the openend of key has been processed tapering.The outer bottom of pipe in following releasing-joint top is sleeved on, following releasing-joint middle part screw thread connects with the draining joint, have the draining hole on the draining joint, the upper and lower installation sealing ring in draining hole, following releasing-joint bottom is sleeved on the draining joint, following releasing-joint lower end is sleeved on outside the sealing ring, and the top of following releasing-joint has processed the key of opening, and the openend of key has been processed tapering.
When slip-type rotation bleeder was gone into the well, draining joint bottom connected oil well pump, and box cupling top connects oil pipe on the oil well pump pump.When operation needs draining, carry oil pipe on the ground, make the key of releasing-joint bottom and the key tabling on following releasing-joint top, rotation pipeline then, slope piece and slips produce relative rotation, under the effect of sloping piece external surface, slips radially opens, since having processed perpendicular shape teeth on the slips, thus can be stuck on the sleeve pipe of oil well, and slips can not be rotated relatively with last releasing-joint, because the key of last releasing-joint bottom and the key tabling on following releasing-joint top, therefore, the moment of ground rotation pipeline makes down the connection screw thread of releasing-joint and draining joint produce shackle, thereby exposes draining hole draining.
Slip-type rotation bleeder of the present utility model, lean on the rotation pipeline draining during draining, when draining can arbitrarily be controlled by artificial, need not drop into instrument and the sucker rod of opening bleeder, not be subjected to the influence of rod parting, before draining, various Job Operations can not cause the bleeder action, therefore, this slip-type rotation bleeder reliable operation, job success ratio height.
Below in conjunction with drawings and Examples the utility model is further specified:
Fig. 1 is a slip-type rotation bleeder structure half sectional view of the present utility model;
Fig. 2 is slip-type of the present utility model rotation bleeder sectional drawing after the A-A disconnection in Fig. 1.
In Fig. 1: the 1st, box cupling, the 2nd, interior pipe, the 3rd, retaining joint, the 4th, support housing, the 5th, slips, the 6th, sloping piece, the 7th, screw, the 8th, last releasing-joint, the 9th, following releasing-joint, the 10th, draining joint, the 11st, sealing ring.Be that slip-type rotation bleeder of the present utility model is made up of box cupling 1, interior pipe 2, retaining joint 3, support housing 4, slips 5, sloping piece 6, screw 7, last releasing-joint 8, following releasing-joint 9, draining joint 10, sealing ring 11.Interior pipe 2 is connected in box cupling 1 time, and the outside of interior pipe 2 is respectively retaining joint 3, support housing 4, slips 5, sloping piece 6, screw 7 from top to bottom, goes up releasing-joint 8, following releasing-joint 9, interior pipe 2 bottoms connection draining joint 10.Pipe 2 outsides in last releasing-joint 8 is set in, last releasing-joint 8 tops connect with retaining joint 3, support housing 4 is sleeved on releasing-joint 8 outsides and is under the retaining joint 3, support housing 4 rises four windows is arranged, sloping piece 6 and slips 5 are installed by Dui Ying two window places respectively, slope piece 6 inwalls contact is on last releasing-joint 8 external surfaces, the circular arc of slope piece 6 inner surfaces does not overlap with the circular arc center of circle of external surface, slope piece 6 usefulness screws 7 are fixed on the releasing-joint 8, the bottom of last releasing-joint 8 has processed the key of opening, and the openend of key has been processed tapering.Pipe 2 outer bottoms in following releasing-joint 9 tops are sleeved on, following releasing-joint 9 middle part screw threads connect with draining joint 10, have the draining hole on the draining joint 10, the upper and lower installation sealing ring 11 in draining hole, following releasing-joint 9 bottoms are sleeved on the draining joint, following releasing-joint 9 lower ends are sleeved on outside the sealing ring 11, and the top of following releasing-joint 9 has processed the key of opening, and the openend of key has been processed tapering.
When slip-type rotation bleeder was gone into the well, draining joint 10 bottoms connected oil well pump, and box cupling 1 top connects oil pipe on the oil well pump pump.When operation needs draining, carry oil pipe on the ground, make the key of releasing-joint 8 bottoms and the key tabling on following releasing-joint 9 tops, rotation pipeline then, slope piece 6 and slips 5 produce relative rotation, under the effect of sloping piece 6 external surfaces, slips 5 radially opens, since having processed perpendicular shape teeth on the slips 5, thus can be stuck on the sleeve pipe of oil well, and slips 5 can not be rotated relatively with last releasing-joint 8, because the key of last releasing-joint 8 bottoms and the key tabling on following releasing-joint 9 tops, therefore, the moment of ground rotation pipeline makes down the connection screw thread of releasing-joint 9 and draining joint 10 produce shackle, thereby exposes draining hole draining.
