Abstract
The utility model relates to a stamping expansion sealing slip well plugger used for plugging returned up high pressure liquid flow in an oil pipe space in the process of work-over treatment with no well killing or spraying in oil fields. The stamping expansion sealed slip well plugger comprises a T-shaped head 9, a connecting body 12, a platen expansion sealing body 19, a tooth plate 23 and other parts, wherein, the T-shaped head 9 is arranged in a an expansion sealing cone 7 of a leather cup. A piston 16, a shield cap 18 and the platen expansion sealing body 19 are arranged in a working barrel 20. A shield hoop 21 arranged in an expansion sealing body 19 of the tooth plate is positioned by a positioning pin 22. The tooth plate 23 is arranged between the working barrel 20 and an end cover 26. The utility model can overcome the resistance of coagulated oil and wax deposition in a well, can plug the well in any positions more tightly, have easier salvage and unsealing operation, and can be reused after wearing parts are replaced. The utility model can plug wells containing coagulated oil and few wax deposition, and also high-pressure oil wells, and raise the adaptive norm of a spray-proof operating machine.
Description
Relate to the field
The utility model relates to not a kind of stifled well device in the open flow workover treatment process of not kill-job of oil field, and the high pressure liquid stream of returning on being used in the shutoff oil pipe space specifically, is the stamping expansion sealed type slip well packer.
Background technology
The tubing plug of oil field use at present can only be fixed on the position, can not adapt to the requirement of not kill-job, in addition, during construction, flies out in well easily.
Technology contents
The purpose of this utility model is to provide a kind of resistance that coagulates oil and wax deposition that can overcome in the well, seals tightlyer, and salvaging, deblocking is easier and reusable stamping expansion sealed type slip well packer.
The utility model is achieved in that and comprises fishing head 1, top connection 2, O type cushion rubber 3, tube connector 4, pressure cap 5, leather cup 6, leather cup expands and seals cone 7, O type cushion rubber 8, T shape 9, O type cushion rubber 10,11, connector 12, connector short circuit 13, pin 14, O type cushion rubber 15, piston 16, O type cushion rubber 17, retaining cap 18, pressing plate expands and seals body 19, seating nipple 20, retaining hoop 21, alignment pin 22, dental lamina 23, turn 24, aluminium pin 25, end cap 26, there is fishing head 1 end of this device, top connection 2 tube connectors 4, pressure cap 5, leather cup 6 connects successively, the leather cup envelope cone 7 that expands is built-in with T shape 9, connector 12 is connected with connector short circuit 13, between connector short circuit 13 and the piston 16 pin 14 is arranged, piston 16 is arranged in the seating nipple 20, retaining cap 18, pressing plate expands and seals body 19, retaining hoop 21 in expanding envelope body 19, dental lamina is arranged, retaining hoop 21 is equipped with dental lamina 23 by alignment pin 22 location between seating nipple 20 and the end cap 26.
Piston 16, retaining cap 18, the bloated envelope of pressing plate body 19 connect successively.
Between dental lamina 23 and the end cap 26 turn 24 is arranged.
The bloated envelope of dental lamina body 19 is connected by aluminium pin 25 with end cap 26.
O type cushion rubber 3 is arranged between top connection 2 and the tube connector 4, between tube connector 4 and the T shape 9 O type cushion rubber 8 is arranged, between T shape 9 and the connector 12 O type cushion rubber 11 is arranged, O type cushion rubber 10 is arranged between seating nipple 20 and the connector 12, O type cushion rubber 15 is arranged on the piston 16.
The bloated envelope of pressing plate cone 7 is made two bodies with piston 16.
Connector has chute, and T shape 9 can be slided in groove.
Advantage of the present utility model is: just it is sent in the well to adopt hollow stem, therefore can overcome the resistance that coagulates oil and wax deposition in the well; Adopt slips anchoring, therefore can be the people with the stifled well in position; Adopted packing element to expand and sealed, therefore sealing is tighter; Salvage, deblocking is easier, can reuse after changing consumable accessory.
This device can carry out shutoff to the well that contains the slight wax deposition of coagulating oil, also can block up well to high pressure oil wells, has improved preventing spraying operation machine accommodation greatly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Concrete enforcement
Mainly be made up of fishing head 1, top connection 2, O type cushion rubber 3, tube connector 4, pressure cap 5, leather cup 6, leather cup the expand envelope body 19, seating nipple 20, retaining hoop 21, alignment pin 22, dental lamina 23, turn 24, aluminium pin 25, end cap 26 of envelope cone 7, O type cushion rubber 8, T shape 9, O type cushion rubber 10,11, connector 12, connector short circuit 13, pin 14, O type cushion rubber 15, piston 16, O type cushion rubber 17, retaining cap 18, pressing plate that expand, its operating principle is:
When setting, with hollow stem this device is delivered in the well behind the assigned address from oil pipe, in hollow stem, suppressed, learn according to Pascal's law at well head, fluid pressure acts on the piston 16, thereby promote that it is descending, the piston 16 descending promotion dental laminas envelope cone 19 that expands is descending, at this moment, the radial component that the bloated envelope of dental lamina cone 19 acts on the dental lamina 23 forces dental lamina 23 outwards to move, along with the increase of pressure, the tooth of dental lamina 23 is bitten tubing wall tightly, has finished the grappling process of well packer.Go up exhaust core barrel post then, top connection 2 like this, tube connector 4, T shape 9, the dental lamina envelope cone 7 that expands is up thereupon, and dental lamina expands envelope cone 19 with the packing element distending.Block the oil pipe inner chamber, continue the upper lifting pipe post, top connection 2 is cut off with the pin of hollow stem junction, takes out hollow stem, finishes stifled well.
During deblocking, be shipped to fisher on the well packer position with hollow stem after, firmly downwards bump top connection 2, under the effect of impact, top connection 2, tube connector 4, T shape 9 is descending, and the dental lamina envelope cone 19 that expands breaks away from packing elements, packing element shrinks under the effect of himself elastic force, thereby packing element connects envelope; Carry fisher then, fisher is caught the fishing head 1 of well packer and is driven that it is up, this moment, the dental lamina envelope cone 19 that expands was up, so dental lamina 23 is also with regard to deblocking.
Adopt the connector 12 of band chute between the first half and the latter half, T shape 9 is slided in groove, drive the dental lamina envelope cone 19 that expands and move up and down, realize the bloated envelope and the deblocking of packing element, thereby packing element and dental lamina two parts are expanded seal and deblocking can be separated.
