Description
Technical field
The present invention relates to the integrated tube rod post of Thickened oil injection-production, specifically a kind of thick oil horizontal well note adopts integral process pipe
Roofbolt and method.
Background technology
As oil field development enters the middle and later periods, the quantity of thick oil horizontal well is continuously increased, at present, and this kind of well is mostly using steaming
The vapour mode of handling up is produced.Former well flow string is needed during turn-week operation, lower steam injection string plays steam injection string, under
Flow string, the job execution under such two two is excessively cumbersome, and heat loss is also increased while increase construction cost.And
Although conventional note, which adopts integrated technique, can accomplish to simplify turn-week process, quick to turn to take out, lower-continuous mapping is limited, it is difficult to
Pump is lowered into horizontal segment, as production later stage liquid level declines, submergence reduces, yield reduction, or even stops production.
By retrieval, in the integrated tube rod column technology field of Thickened oil injection-production, there is presently no find using as the application
Combination.
The content of the invention
Integral process tube rod post and method are adopted it is an object of the invention to provide a kind of thick oil horizontal well note, it is possible to achieve water
The note of flat pump adopts integration, can increase lower-continuous mapping, extend manufacture cycle, and can simplify turn-week process, saves turn-week
Cost, reduces heat loss.
In order to reach above-mentioned purpose, present invention employs following technical scheme, a kind of thick oil horizontal well note adopts integral process
Tube rod post, including tubing string, roofbolt, horizontal injection-extraction pump, the roofbolt are gravity weighted lever post, and the gravity aggravates roofbolt
It is built in inside tubing string, the lower end of the tubing string and roofbolt connects horizontal injection-extraction pump simultaneously.
Also include wellhead hookup, the upper end of the tubing string and roofbolt connects wellhead hookup simultaneously.
The horizontal injection-extraction pump is the horizontal injection-extraction pump of hydraulic power assisted.
It is to use gravity weighted lever in straight well section that the gravity, which aggravates roofbolt,.
In order to reach above-mentioned another object, present invention employs following technical scheme, a kind of thick oil horizontal well note adopts integration
The horizontal injection-extraction pump of hydraulic power assisted, during turn-week, the horizontal segment of oil well is brought into by tubing string and roofbolt by process, pipe
The top connection wellhead hookup of roofbolt, straight well section roofbolt uses gravity weighted lever；
During steam injection, decentralization roofbolt touches pump, the steam injection passage of the tubing string is achieved a butt joint connection, roofbolt is at this moment passed through well head
Suspension arrangement is suspended on well head to keep the straight condition of roofbolt, into steam injection pattern；
By steam injection, stewing well, after open flow, when turning to take out, upper shadoof post makes steam injection passage realize dislocation sealing, production
Passage is unimpeded, into production model.
Compared to prior art, the invention has the advantages that：
(1) the tube rod post can realize that the note of horizontal pump adopts integration, can increase lower-continuous mapping, extend manufacture cycle,
Turn-week process can be simplified again, turn-week cost is saved, heat loss is reduced；
(2) wellhead hookup can make roofbolt be in straight condition in well, it is to avoid the overbending of roofbolt；
(3) gravity accentuation techniques and hydraulic booster technology provide down action edge for the roofbolt, can solve viscous crude oblique greatly
Spend the slow lower problem of roofbolt of well.
Brief description of the drawings
Fig. 1 adopts the structural representation of integral process tube rod post for a kind of thick oil horizontal well note of the invention.
In figure：1- wellhead hookups；2- tubing strings；3- gravity aggravates roofbolt；The horizontal injection-extraction pumps of 4-.
Embodiment
Detailed description for the present invention and technology contents, coordinate brief description of the drawings as follows, but accompanying drawing is only provided with reference to saying
It is bright to be used, not for being any limitation as to the present invention.
According to Fig. 1, a kind of thick oil horizontal well note adopts integral process tube rod post, including tubing string 2, roofbolt, level note are adopted
Pump 4, the roofbolt is gravity weighted lever post 3, and the gravity aggravates roofbolt and is built in inside tubing string, the tubing string and roofbolt
Lower end simultaneously connect horizontal injection-extraction pump.Also include wellhead hookup 1, the upper end of the tubing string and roofbolt connects well simultaneously
Mouth suspension arrangement.The horizontal injection-extraction pump is the horizontal injection-extraction pump of hydraulic power assisted.It is in straight well section that the gravity, which aggravates roofbolt,
Using gravity weighted lever.
Tube rod post composition includes four parts, and combination is：The lower end connection level note of tubular column system and roofbolt system is adopted
The upper end connection wellhead hookup of pump, tubular column system and roofbolt system, roofbolt itself is by the way of gravity exacerbation.
During turn-week, the horizontal injection-extraction pump of hydraulic power assisted is brought into the horizontal segment of oil well by tubing string and roofbolt, tube rod post
Top connects wellhead hookup, and straight well section roofbolt uses gravity weighted lever.During steam injection, decentralization roofbolt touches pump, makes the pipe
The steam injection passage of post achieves a butt joint connection, at this moment roofbolt is suspended on well head to keep roofbolt by wellhead hookup
Straight condition, into steam injection pattern.By steam injection, stewing well, after open flow, when turning to take out, upper shadoof post leads to steam injection
Dislocation sealing is realized in road, and production passage is unimpeded, into production model.
Presently preferred embodiments of the present invention is the foregoing is only, is not used to limit the scope of the claims of the present invention, other use this hair
The equivalence changes of bright patent spirit, all should all belong to the scope of the claims of the present invention.
