Description
Technical field
High pressure underground gas well apparatus field is the utility model is related to, more particularly to a kind of high pressure underground gas well underground is let out
Leak repair apparatus.
Background technology
High pressure underground gas well often in depth under, and its concrete structure is the well casing being vertically arranged by several is connected to
Together；
The link position of adjacent well casing is connected by well casing box cupling（Specific such as Fig. 2,3, wherein well casing are labeled as 1, box cupling
For 2）；
In high pressure underground gas well using after for many years, its collar location due to aging corrosion etc., easily occur between well casing
Gap, cause incident of leakage；
Such case is run into, current processing mode is the high pressure underground gas well of direct waste treatment hair loss life leakage,
Compared with waste of resource, it is also a bigger cost to install new high pressure underground gas well, and economy is bad.
Utility model content
The purpose of this utility model is to overcome the above-mentioned deficiency in the presence of prior art, there is provided one kind delay high pressure
Lower gas storage well service life, economize on resources, the more preferable high pressure underground gas well of economy.
In order to realize above-mentioned purpose of utility model, the utility model provides following technical scheme：
A kind of high pressure underground gas well underground repairing leakage device, it includes：
Inner support pipeline；
Elastomer, the elastomer in a tubular form and are linked on the inner support pipeline（On pipe circumference face）, and elasticity
Body both ends are no more than the both ends of inner support pipeline（Elastomer be filled in after being compressed inner support pipeline outer wall and well casing inwall it
Between, possess outside very big stress, it can make repair apparatus integrally lean on elastomer and adjacent portions caused by this stress
Part is frictionally held in well casing）；
Press pipeline, and the pressure number of tubes is two and is symmetrically connected to the elastomer both ends, the support tube
The pressure pipeline is sheathed with outside the both ends in road respectively, the pressure pipeline and inner support pipeline enclosure are detachably provided with spacing
Device, it can limit slip of the pressure pipeline with respect to inner support pipeline.
The repair apparatus is placed into the well casing of the box cupling leaked when operating with, and is then managed by pressing
Road presses to elastomer, limits slip of the pressure pipeline with respect to inner support pipeline finally by stopping means, elastomer is in pressure
Under can deform upon, be connected with inner support pipeline and well casing inner wall sealing, realize the sealing of the joint to adjacent well casing, so
Even being leaked between box cupling and well casing, because our repairing is inside the well casing of repairing, the fluid in well casing
It will not be spilt again from the joint of adjacent well pipe, so that gap that will not be again between box cupling and well casing outer wall is spilt, increase gas storage
In the life-span of well, without the discarded gas storage well leaked, delay high pressure underground gas well service life, economize on resources, economy
More preferably.
As preferred scheme of the present utility model, the elastomer is divided into two sections, and ring set is provided between two sections of elastomers
The protective in interior supporting pipeline outer wall is closed, such as Fig. 3, it can be seen that, two adjacent well casings at box cupling do not dock completely,
Its federation leaves gap, so just need box cupling to be tightly connected from outside, when one section of elastomer overall structure is used alone,
Because elastomer is squeezed, it can be extruded from the gap of adjacent well pipe, and well casing end always has corner angle, not exclusively smooth, this
Sample may cause the rupture of outer elastomeric surface, influence its sealing effectiveness and service life, set protective effectively to prevent
Such case occurs.
As preferred scheme of the present utility model, the elastomeric material is hydrogenated nitrile-butadiene rubber, and hydrogenated nitrile-butadiene rubber has
There is good oil resistance（It is good to fuel oil, lubricating oil, fragrant series solvent resistance）；And due to its HI SA highly saturated knot
Structure, it is set to have good heat resistance, excellent resistance to chemical corrosion（To freon, acid, alkali have it is good anti-resistance to
Property）, excellent ozone resistance, higher incompressible permanent deformation performance；Hydrogenated nitrile-butadiene rubber also has high intensity simultaneously, high
The features such as tear resistance, excellent anti-wear performance, it is one of supereminent rubber of combination property, the service life of gas storage well is prolonged
Long effect is more preferable.
As preferred scheme of the present utility model, the stopping means is cyclic structure, and supporting pipeline axis is within it
Inner support pipe ends are centrally disposed on, the set-up mode of cyclic structure can make the limit effect of stopping means more preferable, pressure
The relative locking of pipeline and inner support pipeline is more firm.
As preferred scheme of the present utility model, the surface of elastomer outer end annular is plane, the pressure pipeline
Contact surface with elastomer is annular plane, more stable to the pressure transmission of elastomer under pressurized state.
As preferred scheme of the present utility model, the elastomer in the case where turning state naturally, the wall thickness of elastomer be more than or
Equal to the wall thickness of the pressure pipeline, such set-up mode can be such that elastomer preferably fills up between inner support pipeline and well casing
Gap, if pressure pipeline wall ratio elastomer it is big, original state elastomer can't fill up inner support pipeline and
Gap between well casing, it can produce the phenomenon of " S " bending during pressure, reduce elastomer contact with inner support pipeline and well casing
Area, influence its sealing property.
As preferred scheme of the present utility model, the inwall on the pressure pipeline with the one end open of elastomer phase pair is
Domatic, the domatic formation being arranged circumferentially is coniform, and the repair apparatus needs simultaneously to press to elastomer from the pressure pipeline at both ends,
It is a process to pressure, the opposite-grinding device of use is more easy to position to this coniform inwall better adaptability, during so as to pressure
Pressure conduction is more accurate, more preferable to pressure effect so that the installation effect of final elastomer is more preferable, meanwhile, in well casing under
When putting or pulling up article, the guide effect to mobile article is more preferable, is more easy to during decentralization enter pressure pipeline and moves down, pulls up
When, it is possible to prevente effectively from the stuck of article causes the situation that rope breaks.
As preferred scheme of the present utility model, the length of the protective in the axial direction is more than adjacent in the gas storage well
Gap between well casing, elastomer is not touched the gap between well casing because of extruding completely, further ensure elastomer
It is intact, it ensure that its sealing.
Compared with prior art, the beneficial effects of the utility model：
Delay high pressure underground gas well service life, economize on resources, economy it is more preferable.
