The utility model discloses a kind of connection switching device being applicable to the quick anti-flushing well of oilwell water shutoff, go out pipe including blocking agent, pump into pipe, the described pipe that pumps into is connected to blocking agent and goes out the upper end of pipe, and along pumping into pipe obliquely until blocking agent goes out infratubal port direction, it is 120 DEG C that blocking agent goes out to manage and pump into pipe clamp angle.The described pipe that pumps into arranges at least one.Described pump into pipe in arrange pump into tube control flap.Described blocking agent goes out to manage positive upper end connection backwash liquor and goes out pipe, and both axis are consistent.Described backwash liquor goes out to arrange backwash liquor inside pipe and goes out tube control flap.Described gone out by blocking agent pipe, pump into pipe, to go out the connection switching device that pipe constitutes be integral type structure to backwash liquor.Changing-over pipeline flow process when this utility model eliminates anti-flushing well, it is only necessary to be can be achieved with by controlled valve, thus significantly shorten pressure and raise suddenly time spent when needing quick anti-flushing well.
Description
Technical field
This utility model relates to oilfield water blockoff communication apparatus, specifically one, and to be applicable to oilwell water shutoff the most anti-
The connection switching device of well-flushing.
Background technology
During oilfield plug water construction, it sometimes appear that blocking agent blocks in the earth formation, to cause blocking agent to pile up in oil pipe solidifying
Knot, occurs that injection pressure increases to over suddenly the phenomenon of safe pressure limiting, easily causes construction accident.For guaranteeing construction safety, need
Want Rapid Implementation anti-flushing well, in sleeve pipe, generally inject well killing fluid blocking agent is all washed out from oil pipe, before anti-flushing well, need
Disconnecting the pipeline accessing well head, conversion is connected in waste liquid pool, often consumes a longer time with changing-over pipeline owing to disconnecting,
It sometimes appear that the phenomenon that cannot wash out due to blocking agent solidification during anti-flushing well after connecting pipeline, cause construction accident.
Summary of the invention
The purpose of this utility model is to provide a kind of connection switching device being applicable to the quick anti-flushing well of oilwell water shutoff, saves
Changing-over pipeline flow process when having removed anti-flushing well, it is only necessary to be can be achieved with by controlled valve, thus significantly shorten pressure and raise suddenly
Time spent when needing quick anti-flushing well.
In order to reach above-mentioned purpose, this utility model have employed following technical scheme, and it is quick that one is applicable to oilwell water shutoff
The connection switching device of anti-flushing well, goes out pipe including blocking agent, pumps into pipe, described in pump into pipe and be connected to blocking agent and go out the upper end of pipe, and
Along pumping into pipe obliquely until blocking agent goes out infratubal port direction, it is 120 DEG C that blocking agent goes out to manage and pump into pipe clamp angle.
The described pipe that pumps into arranges at least one.
Described pump into pipe in arrange pump into tube control flap.
Described blocking agent goes out to manage positive upper end connection backwash liquor and goes out pipe, and both axis are consistent.
Described backwash liquor goes out to arrange backwash liquor inside pipe and goes out tube control flap.
Gone out by blocking agent pipe, pump into pipe, to go out the connection switching device that pipe constitutes be integral type structure to backwash liquor.
Compared to prior art, this utility model has the advantages that
A kind of connection switching device being applicable to the quick anti-flushing well of oilwell water shutoff of this utility model, when injecting blocking agent, closes
Backwash liquor goes out tube control flap, opens and pumps into tube control flap.During anti-flushing well, close and pump into tube control flap, open backwash liquor
Go out tube control flap.This apparatus structure is simple, easy to use, changes pressure in conventional blocking agent injection process and raises suddenly needs
The problem that quickly during anti-flushing well, changing-over pipeline is the longest, it is only necessary to controlled valve can implement anti-flushing well, it is to avoid dismounting well
Mouth injects the security risk that flow process is brought, it is ensured that the plug water construction smooth and easy operation of safety, is suitable for when oilfield plug water construction
Use.This utility model has only to can be achieved with quick anti-flushing well by controlled valve, changing-over pipeline when eliminating anti-flushing well
Flow process, saves the operating time.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of connection switching device being applicable to the quick anti-flushing well of oilwell water shutoff.
In figure: 1: blocking agent goes out pipe；2: pump into pipe；3: backwash liquor goes out pipe；4: pump into tube control flap；5: backwash liquor goes out management and control
Valve processed；6: blocking agent goes out pipe direction and pumps into pipe angular separation is 120 DEG C.
Detailed description of the invention
Relevant detailed description of the present utility model and technology contents, coordinate accompanying drawing to be described as follows, but accompanying drawing only provide ginseng
Examine and purposes of discussion, be not used for this utility model is any limitation as.
According to Fig. 1, a kind of connection switching device being applicable to the quick anti-flushing well of oilwell water shutoff, go out pipe 1 including blocking agent, pump into
Pipe 2, described in pump into pipe and be connected to blocking agent and go out the upper end of pipe, and along pumping into pipe obliquely until blocking agent goes out infratubal port side
To, it is 120 DEG C that blocking agent goes out to manage and pump into pipe clamp angle.The described pipe that pumps into arranges at least one.Described pump into pipe in arrange pump into pipe
Control valve 4.Described blocking agent goes out to manage positive upper end connection backwash liquor and goes out pipe 3, and both axis are consistent.Described backwash liquor goes out and sets inside pipe
Put backwash liquor and go out tube control flap 5.Gone out by blocking agent pipe, pump into pipe, to go out the connection switching device that pipe constitutes be integral type to backwash liquor
Structure.
In communication apparatus body, when injecting blocking agent, pump truck pipeline is accessed and pumps into pipe 2, open and pump into tube control flap
4, close anti-flushing well control of export valve 5, blocking agent is gone out pipe 1 by blocking agent and injects well head；During anti-flushing well, from sleeve pipe, pump into pressure
Well liquid, closing control valve 4, to open backwash liquor and go out tube control flap 5, liquid backwash gone out goes out pipe control valve by backwash liquor
Door 5 and backwash liquor go out pipe 3 and inject liquid storage tank, and blocking agent goes out pipe direction and pumps into pipe angular separation and be 120 DEG C and reduce injection resistance,
It is more conducive to the smooth and easy injection of blocking agent.
The foregoing is only preferred embodiment of the present utility model, be not used to limit the scope of the claims of the present utility model, its
He uses the equivalence change of patent spirit of the present utility model, all should all belong to the scope of the claims of the present utility model.
