Description
Technical field
The present invention relates to a kind of involving swab, swabbing operation rig tool, more particularly to a kind of steel wire rope pumping return channel.
Background technology
In oilfield exploitation procedure, the pumping that often carry out substantial amounts of formation testing, involving swab, Oil/gas Well discharge opeing etc. is made
Industry, these swabbing operation strokes are typically very long, and substantially from underground, specific a certain depth is extracted into well head always, and its distance is general
There are tens meters to hundreds of meters even to go up km.Because pumping stroke is oversize, swabbing operation can not be using traditional sucker rod pumping machine
Polished rod, and polished rod can only be replaced using the steel wire rope for having certain flexibility.Simultaneously with the Persisting exploitation in oil field, stripper well is got over
Come more, the air content of these wells is small, and borehole pressure is low, be no longer appropriate for being filled using the wellhead sealing designed for high pressure oil wells
It is standby.
The well mouth sealing device that the formation testing of current Oil Field, involving swab swabbing operation are used has continued to use oil-extractor polish-rod substantially
The basic structure of sealing, i.e., by compressing packing box so that there are enough contacts to realize between seal box and steel wire rope
Wellhead sealing；But because steel wire rope itself has helicla flute, to realize that sealing needs the contact bigger than sealing polished rod, but
When the contact between seal and steel wire rope reaches wellhead sealing requirement, swab occurs during descending
Descending situation about being obstructed, so steel wire rope is descending to cross the small requirement of range request resistance in order to meet, scene is mostly using artificial behaviour
The hydraulic pressure or pressurized seal of work.General swabbing operation generally requires two people's compounding practices and completes.
Because the seal of existing steel wire rope sealing device pressure required in use is needed with working condition
Difference and be changed, and using disposable sealing, determine that its effect is bad.Meanwhile, in swabbing operation, normal pumping
Speed does relative toward sliding friction between 1.96-3.98 meter per seconds, between steel wire rope and packing, weares and teares quickly, when often working
Between packing not long just lose sealability.Because steel wire rope itself has thread groove, ensureing that steel wire rope being capable of normal work
In the case of, even if imposing severe pressure, the seal pressure between packing and steel wire rope is improve, in actual applications, still
Have the problems such as leakage scene, the hidden danger that causes to catch fire, well head pollution and difficult operation.
Therefore, during steel wire rope swabbing operation, certain leakage phenomenon will necessarily be produced, is directed to this, if will leakage
The fluid for going out reclaims to imported into pipeline by a device will well solve steel wire rope sealing problem.
The content of the invention
In view of this, the invention provides a kind of steel wire rope well head receding machine, it is used to reclaim in steel wire rope swabbing operation and lets out
Reveal the fluid for producing, to ensure the safety in production in oil field.
What the embodiment of the present invention was realized in；
A kind of sealing device for oil steel wire rope well, including oil collecting pipe, centralizer, draining pressure head, O-ring seal, packing, packing
Box, drainpipe, water pipe buckle, check valve and well head soldering.
Described oil collecting pipe is used to collect the fluid revealed during steel wire rope swabbing operation, can be existed according to actual conditions
Install insulation belt or end cap additional outward.
Described centralizer is arranged between oil collecting pipe and draining pressure head, it is ensured that steel wire rope direction vertically, controls steel wire rope
Vibration amplitude, while can according to circumstances install additional filter screen and oil jacket is scraped, it is ensured that return flow line it is smooth.
The draining pressure head is arranged on packing box, fixed packing position, applies pressure；Drainpipe is connected simultaneously outwards to arrange
Water, can according to circumstances install insulation belt additional.
The packing using internal layer is thin, outer thickness structure, the similar structure as hairbrush of multiple combined schedules, every layer
Can all play a part of to strike off steel wire rope surface and depend on thing.
The drainpipe is arranged between draining pressure head and well head soldering, is used to discharge the fluid in oil collecting pipe, uses buckle
It is fixed on interface.
The check valve uses low-pressure valve, it is ensured that fluid is not countercurrently.Magnetic valve can according to circumstances be selected.
The well head welding, is connected on well head and valve.
The present invention has advantages below；
1st, thin outer thick structure in packing, is effectively reduced the contact between steel wire rope, extends packing service life；
2nd, the space for existing between packing and packing, can make packing produce certain change according to the up and down motion of steel wire rope
Shape, can also store the smooth steel wire rope of a small amount of fluid, it is to avoid reeled off raw silk from cocoons during steel wire rope up-downgoing, beat the phenomenons such as torsion, extension
Service life.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
Reference：1-oil collecting pipe；2-centralizer；3-draining pressure head；4-O-ring seal；5-packing；6-packing
Box；7-drainpipe；8-water pipe buckle；The soldering of 9-well head；10-check valve.
Specific embodiment
Below in conjunction with accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that institute
The embodiment of description is only a part of embodiment of the invention, rather than whole embodiments.Give embodiments of the invention,
All embodiments that those of ordinary skill in the art are obtained under the premise of creative work is not made, belong to guarantor of the present invention
The scope of shield.
Refer to Fig. 1：A kind of steel wire rope pumping return channel, including oil collecting pipe 1, centralizer 2, draining pressure head 3, packing 5, disk
Root box 6, drainpipe 7, well head soldering 9 and check valve 10.Wherein well head soldering 9 is welded by oil pipe and discharge outlet, is connected to
Between well head four-way and valve；Packing box 6 is fixed on well head by standard tubing thread, and inside is put into multiple packings 5, Ran Houyu
Draining pressure head 3 is connected, and the position of packing 5 is fixed by fastening draining pressure head 3；Individual event valve 10 is fixed on well head soldering discharge outlet
On；The connection draining of drainpipe 7 pressure head 3 and well head soldering 9；Centralizer 2 be arranged on draining pressure head 3 in, oil collecting pipe 1 by screw thread with
Draining pressure head 3 is connected, while the position of fixed centralizer.
Operation principle of the present invention：
When steel wire rope is up, the multilayer packing for having class hair brush structure strikes off the fluid that steel wire rope surface depends on, and steel wire rope leads to
Cross draining pressure head 3, centralizer 2 to move upwards, due to the vibrations in itself of gravity and steel cable, the fluid for depending on can be scattered in oil collecting pipe
In 1, when steel wire rope is descending, check valve 9 is opened, and the fluid of collection can be by centralizer 2, draining pressure head 3, drainpipe 7, check valve
9 and well head soldering 10 enter pipeline in, complete pumping.And thin outer thick structure in packing, be effectively reduced with steel wire rope it
Between contact, extend packing service life；The space existed between packing and packing, can make packing according to the upper and lower of steel wire rope
Motion produces certain deformation, can also store the smooth steel wire rope of a small amount of fluid, it is to avoid reeled off raw silk from cocoons during steel wire rope up-downgoing,
The phenomenons such as torsion are beaten, is increased the service life.
