Suitable for high angle hole and horizontal well.
Utility model content
The utility model can substitute conventional mainly solving the technical problems that provide a kind of ultra dense envelope hook-up for cementing
Rubber plug can be applied in high angle hole or horizontal well.
In order to solve the above technical problems, the technical solution that the utility model uses is: providing a kind of ultra dense envelope water filling
Mud device, comprising: rubber plug core, rubber, circlip and sealing ring, the rubber is by several support chips and several diaphragm seal groups
At the rubber hot pressing sticks on the rubber plug core, and the sealing ring is mounted on the front end of the rubber plug core, the circlip
The front end of the rubber plug core and the circlip are mounted between the sealing ring and rubber.
In one preferred embodiment of the utility model, the rubber is by the identical support chip of 6 structures and 2 structure phases
Same diaphragm seal composition.
In one preferred embodiment of the utility model, 6 support chips are divided into two groups of supporters up and down, every group of support
Body is made of the support chip that 3 equidistant hot pressing stick on rubber plug core.
In one preferred embodiment of the utility model, hot pressing sticks in every group of supporter to 2 diaphragm seals respectively
Lower section.
In one preferred embodiment of the utility model, the support chip is rubber piece, and the diaphragm seal is rubber
Diaphragm seal.
In one preferred embodiment of the utility model, the outer diameter of the diaphragm seal is slightly larger than the outer diameter of the support chip.
If the beneficial effects of the utility model are: the utility model by being arranged outside rubber plug core by several support chips and
The rubber of dry diaphragm seal composition, is supported by several support chips, it is ensured that the centralizer of the hook-up for cementing leads to simultaneously
Cross circlip and sealing ring progress secondary seal that several diaphragm seals carry out once sealing, are arranged by rubber plug core front end, it is ensured that
The hook-up for cementing have reliable sealing performance, thus make the utility model hook-up for cementing can be applied to high angle hole or
In horizontal well, and cementing quality can be improved, guarantee safety in production.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of ultra dense one preferred embodiment of envelope hook-up for cementing of the utility model；
The components in the drawings are labeled as follows: 1, rubber plug core, 2, rubber, 21, support chip, 22, diaphragm seal, 3, circlip, 4,
Sealing ring.
Specific embodiment
The preferred embodiment of the utility model is described in detail with reference to the accompanying drawing, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, to make the protection scope of the utility model apparent clear
Define.
Referring to Fig. 1, the utility model embodiment includes:
A kind of ultra dense envelope hook-up for cementing, comprising: rubber plug core 1, rubber 2, circlip 3 and sealing ring 4, if the rubber 2 by
Dry support chip 21 and several diaphragm seals 22 form, and 2 hot pressing of rubber sticks on the rubber plug core 1, pass through support chip
21 pairs of hook-up for cementing are supported between two parties, ensure the sealing in the hook-up for cementing use process by diaphragm seal 22
Property；The sealing ring 4 is mounted on the front end of the rubber plug core 1, the circlip 3 be also mounted at the front end of the rubber plug core 1 and
For the circlip 3 between the sealing ring 4 and rubber 2, circlip 3 described in use process can realize that device is self-locking, and pass through
Sealing ring 4 realizes secondary seal.
Preferably, the rubber 2 is made of the identical diaphragm seal 22 of identical support chip 21 and 2 structure of 6 structures.
Further, 6 support chips are divided into two groups of supporters, every group of supporter up and down and are glued by 3 equidistant hot pressing
The support chip 21 being connected on rubber plug core 1 forms.Hot pressing sticks in the lower section of every group of supporter to 2 diaphragm seals 22 respectively.
Wherein, the support chip 21 is rubber piece, and the diaphragm seal 22 is rubber gasket, using rubber material,
Make support chip 21 and diaphragm seal 22 that there is good intensity and elasticity, can ensure that centralizer and leakproofness.
Further, the outer diameter of the diaphragm seal 22 is slightly larger than the outer diameter of the support chip 21, it is ensured that sealing reliability.
The utility model discloses a kind of ultra dense envelope hook-up for cementing, by being arranged outside rubber plug core by several support chips
With the rubber of several diaphragm seals composition, it is supported by several support chips, it is ensured that the centralizer of the hook-up for cementing, together
