Description
Technical field
The present invention relates to injection well pipe column, specifically a kind of pipe string of oil-water well axial vibration absorber.
Background technology
Current domestic conventional waterflooding well is all to be pressurized under the unified regulation of ground water-injection station using booster pump, passes through ground water filling
Pipeline enters well.Due to the vibration characteristics and waterflood-transmission line unstability of water-injection station booster pump, injection liquid stream is also easy to produce
Fast is unstable, injection well pipe column is also easy to produce axial vibration.The method that some oil fields are exploited using vibration：There is underground to surpass
Acoustic vibration method, down-hole mechanical vibratory drilling method and underground shock wave method etc. achieve certain effect, but because to tubing string by
Power situation optimizes, and causes water injection string working environment to deteriorate, also easily makes the life tools such as supporting packer, hydraulic anchor
Lower, or even failure, cause vibration production practice to fail to promote the use of a large area in oil field.
The content of the invention
It is an object of the invention to provide a kind of pipe string of oil-water well axial vibration absorber, simple and reliable for structure, field conduct
Method is easy, is effectively improved tubing string and kit working condition.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of pipe string of oil-water well axial vibration absorber,
Including base tube, oscillator, elastic device, the oscillator is enclosed on the outside of base tube and forms annular space, the elasticity between the two
Device is installed in above-mentioned annular space.
The elastic device is that disc spring combines either rubber air bag or compression spring.
Inner chamber is provided with step in the middle part of the oscillator, and the annular space between oscillator and base tube is separated under annular space epicoele and annular space
Chamber, elastic device is respectively provided with the annular space epicoele and annular space cavity of resorption.
Step upper surface in the middle part of the oscillator coordinates with upper heelpiece ring gap, and step lower surface is matched somebody with somebody with lower top packing ring gap
Close, step is provided with the outside of the base tube upper end, step lower surface coordinates with upper top packing ring gap, passed through outside the base tube
Engagement thread is also arranged clamping sleeve and clenched admittedly with locking, and lower bottom rubber ring is withstood in the clamping sleeve upper surface.
Elastic device upper end in the annular space epicoele, which abuts, pushes up packing ring, and lower end abuts upper bottom rubber ring, the annular space cavity of resorption
In elastic device upper end abut lower top packing ring, lower end abuts lower bottom rubber ring.
The oscillator external cylindrical surface is threaded and is arranged extra block, and screw thread coordinates with extra block internal thread gap.
Described extra block is clenched admittedly with oscillator with locking.
Compared to prior art, the invention has the advantages that：
(1) process pipe string is improved because of tubing string vibrational state caused by water filling, the stability of safeguards containment device working condition,
Extend water injection string in the well life-span.
(2) tool construction is simple and reliable, and site construction technology is simple.
Brief description of the drawings
Fig. 1 is a kind of structural representation of pipe string of oil-water well axial vibration absorber；
Fig. 2, Fig. 3 are the structure chart of other two kinds of embodiments.
In figure：Base tube 1, it is upper top packing ring 2, upper disc spring combination 3, oscillator 4, upper bottom rubber ring 5, it is lower top packing ring 6, under
