Description

A kind of seal modules suitable for sand control treatment

Technical field

The utility model is related to a kind of seal modules, and more specifically, the utility model is related to one kind being used for sand control treatment Seal modules.

Background technology

Currently, with the continuous development of offshore oil exploitation technology in offshore oil industry, sand control completion technology is not yet Disconnected improvement and innovation, therefore the requirement to sand preventing tool is also higher and higher.

Include a variety of seal forms in the sand control pipe of sand control treatment, such as packing element seals, O circle sealings, seal modules are close Envelope is also one of which, it is suitable for multiple types of tools, can cooperatively form ring packing with corresponding sealing drum.

The structure type of conventional seals module mainly has following two：

Referring to Fig.1, the both sides of this kind of seal modules are metalwork 1, and centre is bottom whole rubber structure 2 outstanding.This The advantages of kind of seal modules is good airproof performance, is not easy long-pending sand, but the disadvantage is that due to the interference volume of rubber 2 cause greatly it is not easy to install, And the volume of rubber structure 2 accounts for major part, and overall deformation is very big, encounters small step or sand is easy to it It scratches and even tears, so as to cause seal failure.

With reference to Fig. 2, this kind of seal modules are matrix with metalwork 1, and the section structure of the metalwork 1 is upper lobes And seal groove is provided among bottom, the both sides of the upper lobes are respectively arranged with sealing strip 3 and are used as external seal, in the bottom Between seal groove internal clearance cooperation mounting O-shaped rings 4 realize interior sealing.The advantages of this seal modules is to facilitate installation, tear-proof Scratch resistance is strong, but disadvantage, in being installation process, O-ring 4 is easy to be sheared or reverse, and tiny sand be easy into Enter to seal clearance and generate product sand, to cause to damage to the sealing surface of module.

As it can be seen that existing seal modules technology, it is capable of anti-long-pending sand and is not easy to install, and be easy tearing；Convenient for fast pacifying Dress again cannot anti-long-pending sand, and seal be easy failure, have different degrees of shortcomings and deficiencies.

Utility model content

The purpose of this utility model be exactly overcome the deficiencies of existing technologies with it is insufficient, and provide a kind of novel be used for thus The seal modules of sand control treatment, the application of novel seal module can solve the above-mentioned prior art in actual use many and ask Topic, to improve operation quality.

The technical solution of the utility model is：

A kind of seal modules for sand control treatment include the metalwork as matrix, the section structure of the metalwork For the shape of plane, the centre of the lower part protrusion plane are protruded with upper lobes plane and lower part on the basis of rectangular Position is provided with groove, and the first vulcanized rubber is respectively set in the both sides of the upper lobes plane, and the two of plane are protruded in the lower part The second vulcanized rubber is respectively set in the groove at side and intermediate position, the upper plane of first vulcanized rubber is higher than the metal The lower plane of the upper lobes plane of part, second vulcanized rubber protrudes plane less than the lower part of the metalwork.

The utility model overcomes the shortcomings of the prior art, and advantage is：

(1) inside and outside sealing is vulcanized rubber attachment, and the O circle sealings for avoiding the prior art easy to produce torsion and cut Cut the deficiency of phenomenon.

(2) by the reasonable computation of sealing performance, it can be achieved that between vulcanized rubber and metalwork most suitable interference volume tune It is whole, both can guarantee installation, dismounting it is convenient and efficient, ensure that the moderately good of sealing performance.

(3) by adjusting the hardness of vulcanized rubber and tearing strength, it is ensured that it encounters flat when tiny step or sundries Slide-through is crossed without causing to damage.

(4) since there is no clearance fit the problem of, therefore long-pending sand phenomenon can be effectively avoided, to the sealing of protection module Face is not damaged, and is reduced and is replaced number.

(5) it installs, dismantle the auxiliary tool that can continue to use original module, tool is increased newly without addition.

(6) to the adaptable of operating environment, the deficiency of conventional module is not only compensated for, but also can replace into mouth mold Block is easy to implement production domesticization, to reduce operating expenses.

Specific implementation mode

In order to make the utility model be easier to be understood, with reference to the accompanying drawings and embodiments to the skill of the utility model Art scheme is described in detail.

With reference to Fig. 3, the seal modules for sand control treatment of the utility model include the metalwork 1 as matrix, described The section structure of metalwork 1 is the shape with upper lobes plane and lower part protrusion plane on the basis of rectangular, and under The intermediate position of portion's protrusion plane is provided with groove, and the first vulcanized rubber 5 is respectively set in the both sides of the upper lobes plane, described The second vulcanized rubber 6 is respectively set in the both sides of lower part protrusion plane and the groove at intermediate position, first vulcanized rubber 5 Upper plane is higher than the upper lobes plane of the metalwork 1, and the lower plane of second vulcanized rubber 6 is less than the metalwork 1 Lower part protrude plane.

First vulcanized rubber 5 of 1 upper lobes plane both sides of the metalwork is for realizing external seal, the lower part protrusion The second vulcanized rubber 6 in plane both sides and intermediate position groove is for realizing interior sealing.

The technical solution of the utility model is schematically described above by reference to drawings and examples, which does not have It is restricted.Those skilled in the art will be understood that in practical applications, metalwork and rubber structure in the utility model Set-up mode be possible to that certain changes occur according to the needs of actual conditions, and other staff may also do under its enlightenment Go out similar Design.In particular, it should be pointed out that without departing from the design aim of the utility model, all obvious changes And its similar Design, it is all contained within the scope of protection of the utility model.
