Description
Technical field
The utility model belongs to oil gas field equipment technical field more particularly to a kind of packing of compression fission MESH (grid)
Device seal assembly.
Background technology
In recent years, with the continuous improvement of exploration and development technique, underground operation tool is to achieve the purpose that several work,
Annular space between increasing tubing string and casing is not only blocked, but also can be used in annular between plugging tubing string and bore hole
Space.
And important component of the seal assembly as downhole tool, heatproof, pressure resistance and corrosion resistance directly affect
To the using effect of downhole tool and service life etc..Seal assembly when working in corrosive high temperature subsurface environment,
High Pressure Difference need be born, seal assembly shoulder is easily squeezed out by High Pressure Difference and destroyed, and leads to seal failure, to cause downhole tool
Resistance to pressure difference is low, service life is given and shortened.With the application of bore hole downhole tool, seal assembly is not only wanted being capable of plugging tubing string and set
Larger annular space between pipe, but also want the irregular gap for capableing of plugging tubing string and open hole wall.Existing seal assembly by
It is limited, is not applied in all pounds of grade casings of same size in technology.This to the design of downhole tool, production, use
Process brings many difficulties.In conclusion existing routine downhole tool seal assembly is difficult to meet above-mentioned working condition requirement, therefore urgently
A kind of reliable seal assembly is needed to ensure the normal use requirement of downhole tool.
Invention content
Place in order to overcome the above-mentioned deficiencies of the prior art, the utility model provide a kind of compression fission MESH packers
Seal assembly, the seal assembly can realize in same size in all pounds of grade casings, being capable of plugging tubing string and open hole well wall pieces
Irregular gap.
To achieve the above object, the utility model adopts the following technical solution：A kind of compression fission MESH packers are close
Sealing assembly, including intermediate packing element and end packing element, the intermediate packing element are compressible packing element made of high molecular material, and packing element
In be equipped with corrosion resistant metal grill, the both ends of intermediate packing element are respectively equipped with an end packing element, and end packing element is high molecular material system
At, including seperated molding ontology and fission, the ontology with it is seperated in be equipped with corrosion resistant metal grill, and ontology and divide
Internal metal grill angle is different, seperated that chamfering is equipped at outer end.
In the above-mentioned technical solutions, the inner wall middle of the intermediate packing element is equipped with one of groove.
In the above-mentioned technical solutions, the section of the groove is small trapezoidal of outer imperial palace.
In the above-mentioned technical solutions, the contact surface of the intermediate packing element and end packing element is inclined-plane.
In the above-mentioned technical solutions, the high molecular material that the intermediate packing element and end packing element use is nitrile rubber, hydrogenation
Nitrile rubber, fluorubber,At least one of FFKM, PTFE.
The utility model has the beneficial effects that：
1. using the ends the MESH packing element with certain elasticity, annular space that can not only be between plugging tubing string and casing, and
And can be between plugging tubing string and open hole wall irregular gap；
2. the seal assembly uses the high molecular material of high temperature resistant, corrosion resistant high intensity, can be reached in 212 ℉, pressure-bearing
To 10K Psi, and being capable of hydrogen sulfide corrosion-resistant；
3. using the intermediate gum cover of the ends the MESH gum cover and compressible deformation with certain elasticity, seal assembly is compressible,
And sealing effect is good, service life is long；
4. the utility model can be used in the casing of same size difference pound grade.
Description of the drawings

Body 4, the ontology 3 with corrosion resistant metal grill 2, and ontology 3 and 2 angle of metal grill in seperated 4 are equipped in seperated 4
Difference, fission 4 are equipped with chamfering 5 at outer end.
In the above-mentioned technical solutions, the inner wall middle of the intermediate packing element 1 is equipped with one of groove 6.
In the above-mentioned technical solutions, the section of the groove 6 is small trapezoidal of outer imperial palace.
In the above-mentioned technical solutions, the contact surface of the intermediate packing element 1 and end packing element is inclined-plane.
In the above-mentioned technical solutions, the high molecular material that the intermediate packing element 1 and end packing element use is nitrile rubber, hydrogenation
Nitrile rubber, fluorubber,At least one of FFKM, PTFE.
Across pound grade, which refers to the utility model, can be used in same size but the different a variety of casings of pound grade.
The ontology 3 and fission 4 for holding packing element are formed by curing by high molecular material high temperature and pressure, 3 part of ontology leaching before curing
Coating adhesive ensures and the adhesive strength after high molecular material solidification.Intermediate packing element directly injects mold by high molecular material, warp
High temperature high-pressure curing is crossed to form.
