Description
Technical field
The utility model is related to a kind of capping tools for insulating bottom oil, gas and water layer in the mines such as oil well, gas well,
More particularly to a kind of packer.
Background technology
In oilfield development process, in order to solve interlayer contradiction, the well water rate of climb and oil field composite water cut are controlled
The rate of climb, it is necessary to carry out seperated layer water injection.Packer is the essential tool during seperated layer water injection, packer be located at oil pipe and
Between sleeve pipe, when the packing element of packer bears axial load, packing element axial crushing deformation and radial expanding deformation oil can be made so that
Contact is produced between packing element and sleeve pipe, the contact can seal the circular passage between oil pipe and internal surface of sleeve pipe, finally
Realize blocking in DP technology.
At present, the structure of packer generally comprises top connection 2, packer body 3, lower contact 4 and transition joint 1, and in
Between joint 1 be arranged on the medium position of packer body 3, it is O-shaped to be additionally provided with one between transition joint 1 and packer body 3
Sealing ring 5.In said structure, transition joint 1 and packer body 3 realize sealing by O-ring seal 5, its be specifically
The annular groove of the insertion of an appearance O-ring seal 5 is opened on the outer wall of transition joint 1, using this sealing means, O-ring seal 5 is pacified
Fill unstable, be susceptible to displacement, and 0 star sealing ring 5 with, for point is contacted, sealed between transition joint 1 and packer body 3
Effect is bad.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of packer of good seal performance.
In order to solve the above technical problems, the technical solution of the utility model is：A kind of packer, its innovative point is：Bag
Include
One packer body, the packer body is a circular tube structure, is respectively fixedly connected with the two ends of packer body
There are a top connection, a lower contact, the top connection is circular ring structure with lower contact, and the internal diameter of top connection is more than packer master
The internal diameter of body；
One transition joint, the transition joint is arranged in packer body and is located therein position, in transition joint
A T-shaped sealing ring is additionally provided between packer body, the T-shaped sealing ring is close to the outer wall and packer of transition joint respectively
The inwall of main body, the T-shaped sealing ring is fixed in transition joint by a limit screw cap, the stop nut and transition joint
Between be screwed, while having one to hold the T-shaped through hole that T-shaped sealing ring is installed on stop nut.
The utility model has the advantage of：In the utility model, for using T between transition joint and packer body
Type sealing ring forms sealing, so as to increase T-shaped sealing ring and transition joint, the contact area of packer body, improves sealing
Effect, in addition, being fixed in transition joint using stop nut for T-shaped sealing ring, and coordinates the shape of T-shaped sealing ring, from
And T-shaped sealing ring is carried out well spacing, it is to avoid it is subjected to displacement, it is ensured that sealing effectiveness.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the schematic diagram of traditional packer.
Fig. 2 is the schematic diagram of the packer in the utility model.
Fig. 3 is the A portions enlarged diagram of Fig. 2.
Specific embodiment
The following examples can make professional and technical personnel that the utility model is more fully understood, but therefore will not
The utility model is limited among described scope of embodiments.
A kind of packer as shown in Figure 2, including
One packer body 1, the packer body 1 is a circular tube structure, and at the two ends of packer body 1, fixation connects respectively
A top connection 2, a lower contact 3 are connected to, top connection 2 is circular ring structure with lower contact 3, and the internal diameter of top connection 2 is more than packing
The internal diameter of device main body 1, internal thread is provided with the left end of lower contact 3, and the right-hand member of packer body 1 is provided with external screw thread, lower contact 3
The right-hand member of left end and packer body 1 is connected through a screw thread fixation, so left end and the packer body 1 of lower contact 3 right-hand member
A step surface being close to is formed, the internal diameter of lower contact 3 is equal to the internal diameter of packer body 1.
One transition joint 4, schematic diagram as shown in Figure 3 understands that transition joint 4 is arranged in packer body 1 and is located at
Its medium position, is additionally provided with a T-shaped sealing ring 5 between transition joint 4 and packer body 1, and the T-shaped sealing ring 5 is distinguished
It is close to the outer wall of transition joint 4 and the inwall of packer body 1, T-shaped sealing ring 5 is indirect in being fixed on by a limit screw cap 6
On first 4, it is screwed between stop nut 6 and transition joint 4, while have one to hold T-shaped sealing ring 5 on stop nut 6 pacifying
The T-shaped through hole of dress.For forming sealing using T-shaped sealing ring 5 between transition joint 4 and packer body 1, so as to increase T
Type sealing ring 5 and transition joint 4, the contact area of packer body 1, improve sealing effectiveness, in addition, being adopted for T-shaped sealing ring 5
It is fixed in transition joint 4 with stop nut 6, and coordinates the shape of T-shaped sealing ring 5, so as to enters to T-shaped sealing ring 5 well
Row is spacing, it is to avoid it is subjected to displacement, it is ensured that sealing effectiveness.
It should be understood by those skilled in the art that, the utility model is not restricted to the described embodiments, above-described embodiment and
Principle of the present utility model simply is illustrated described in specification, on the premise of the utility model spirit and scope are not departed from,
