Description
Technical field
The present invention relates to high pressure underground gas well apparatus field, more particularly to a kind of high pressure underground gas well underground leakage is repaiied
Mend device.
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, and box cupling is
2）；
In high pressure underground gas well using after for many years, its collar location due to aging corrosion etc., between easily occurring and between well casing
Gap, causes 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, more unrestrained
Take resource, it is also a bigger cost to install new high pressure underground gas well, and economy is bad.
The content of the invention
It is an object of the invention to overcome the above-mentioned deficiency in the presence of prior art, there is provided one kind postpones high pressure subterranean storage
Gas well service life, economize on resources, the more preferable high pressure underground gas well of economy.
In order to realize foregoing invention purpose, the invention 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 is linked on the inner support pipeline（On pipe circumference face）, and elastomer two
Two ends of the end no more than inner support pipeline（Elastomer is filled between the outer wall of inner support pipeline and well casing inwall after being compressed,
Possesses outside very big stress, it can make elastomer and adjacent component of the repair apparatus integrally by the generation of this stress
It is frictionally held in well casing）；
Pressure pipeline, the pressure number of tubes is for two and is symmetrically connected to the elastomer two ends, the support pipeline
The pressure pipeline is sheathed with outside two ends respectively, the pressure pipeline and inner support pipeline enclosure are detachably provided with spacing dress
Put, it can limit slip of the pressure pipeline with respect to inner support pipeline.
The repair apparatus are placed into the well casing of the box cupling for leaking when operating with, and are then managed by pressing
Road presses to elastomer, the slip finally by stopping means limitation pressure pipeline with respect to inner support pipeline, and elastomer is in pressure
Under can deform upon, be connected with inner support pipeline and well casing inner wall sealing, realize the sealing to the joint of 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
Joint that will not be again from adjacent well pipe spills, so that gap that will not be again between box cupling and well casing outer wall spills, increases gas storage
The life-span of well, without discarding the gas storage well that leaks, delay high pressure underground gas well service life, economize on resources, economy
More preferably.
Used as preferred scheme of the invention, the elastomer is divided into and is provided with ring between two sections, two sections of elastomers and is linked in
The protective of inner support tube pipeline outer wall, such as Fig. 3 be can see, and the adjacent well casing of two at box cupling is not docked completely, and its is total
Gap can be left, so just need box cupling to be tightly connected from outside, when one section of elastomer overall structure is used alone, due to
Elastomer is squeezed, and it can be extruded from the gap of adjacent well pipe, and well casing end always has corner angle, not exclusively smooth, so may be used
The rupture of outer elastomeric surface can be caused, its sealing effectiveness and service life is influenceed, setting protective can effectively prevent this
Situation occurs.
Used as preferred scheme of the invention, the elastomeric material is hydrogenated nitrile-butadiene rubber, and hydrogenated nitrile-butadiene rubber has good
Good oil resistance（It is good to fuel oil, lubricating oil, fragrant series solvent resistance）；And due to its HI SA highly saturated structure, make
The good heat resistance of its tool, excellent resistance to chemical corrosion（To freon, acid, alkali with good resistance）, it is excellent
Different ozone resistance, incompressible permanent deformation performance higher；Hydrogenated nitrile-butadiene rubber also has high intensity, high tear simultaneously
Can, be one of supereminent rubber of combination property, to the service life prolongation effect of gas storage well the features such as anti-wear performance is excellent
More preferably.
Used as preferred scheme of the invention, the stopping means is cyclic structure, and it is centered on inner support tube road axis
Inner support pipe ends are arranged in, the set-up mode of cyclic structure can make the limit effect of stopping means more preferable, and press pipeline
Relative locking with inner support pipeline is more firm.
Used as preferred scheme of the invention, the surface of the elastomer outer end annular is plane, the pressure pipeline and bullet
The contact surface of gonosome is the plane of annular, and under pressurized state, the pressure transmission to elastomer is more stable.
Used as preferred scheme of the invention, in the case where state is turned naturally, the wall thickness of elastomer is more than or equal to the elastomer
The wall thickness of the pressure pipeline, between such set-up mode can be such that elastomer preferably fills up between inner support pipeline and well casing
Gap, if the wall ratio elastomer of pressure pipeline is big, original state elastomer can't fill up inner support pipeline and well casing
Between gap, it can produce the phenomenon that " S " bends during pressure, reduce the contact surface of elastomer and inner support pipeline and well casing
Product, influences its sealing property.
With the inwall of the one end open of elastomer phase pair it is slope on the pressure pipeline as preferred scheme of the invention
Face, the domatic formation being arranged circumferentially is coniform, and the repair apparatus need simultaneously to press elastomer from the pressure pipeline at two ends, are
One process to pressing, the opposite-grinding device of use is more easy to positioning to this coniform inwall better adaptability, is pressed during so as to pressure
Power conduction is more accurate, to pressure effect more preferably, so that the installation effect of final elastomer is more preferably, meanwhile, transferred in well casing
Or during pull-up article, the guide effect to mobile article is more preferable, it is more easy to enter pressure pipeline and move down during decentralization, pulls up
When, it is possible to prevente effectively from the stuck situation for causing rope to break of article.
Used as preferred scheme of the invention, protective length in the axial direction is more than adjacent well casing in the gas storage well
Between gap, elastomer is not touched gap between well casing because of extruding completely, further ensure the intact of elastomer,
Ensure that its sealing.
Compared with prior art, beneficial effects of the present invention：
Postpone high pressure underground gas well service life, economize on resources, economy it is more preferable.
