Description
Technical field:
The utility model relates to thermal recovery, fireflood oil well and fractured well sand washing operation technical field, in particular to a kind of water
Power is crushed sand flushing device.
Background technique:
During thermal recovery, fireflood oil well and fractured well sand washing operation, due to sand face is cementing or oil well fracturing operation in
Fracturing sand forms sand bridge, and conventional sand flushing tool impact force is insufficient, and it is slow or rush motionless sand washing drilling depth occur, and it is hard can not to break sand face
Shell, operating efficiency is low, causes subsequent job process that can not carry out, seriously affects oil well and reproduce.
Utility model content:
The technical problem to be solved by the present invention is to provide a kind of hydraulic fracture sand flushing devices, and the arrangement achieves can
Effectively broken sand face carries out sand washing operation, and operating efficiency is high, avoids to rise out again since conventional sand flushing tool operation is unsuccessful
Sand-flushing pipe column changes the process of lower milling tubing string, saves operating cost, and structure novel, working performance is safe and reliable, easy to use,
It is low in cost.It is insufficient to overcome existing sand flushing tool impact force, the deficiency of sand washing difficulty.
Technical solution adopted in the utility model is: a kind of hydraulic fracture sand flushing device, including top connection；In top connection
Rotation assembly is equipped in portion's limiting slot, rotation assembly lower end connects central tube, is equipped with ball-and-seat on central tube, central tube passes through
Drive assembly, drive assembly are connected to top connection lower end, and central tube lower end connects hollow scraper, is provided with hydrophthalmia on hollow scraper,
Design has a single flow channel on the inner cavity of rotation assembly lower end, and drive assembly lower end inner cavity is equipped with single flow channel, and liquid is from rotation assembly
Single flow channel on inner cavity passes into drive assembly internal rotating blade and flows out to center from drive assembly lower end single flow channel
Inside pipe, liquid is able to drive rotating vane rotation when flowing through drive assembly internal rotating blade, rotating vane rotation being capable of band
Dynamic central tube rotation.
The beneficial effects of the utility model are: the utility model, which realizes, can effectively be crushed sand face progress sand washing operation,
Operating efficiency is high, avoids to play out sand-flushing pipe column again since conventional sand flushing tool operation is unsuccessful, changing the work of lower milling tubing string
Sequence saves operating cost, and structure novel, working performance is safe and reliable, easy to use, low in cost.
Detailed description of the invention:
The utility model is described in more detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural schematic diagram of the utility model reacting cycle state.
Fig. 2 is the structural schematic diagram of the utility model positive recurrent state.
Specific embodiment:
As shown in Figure 1 and Figure 2, a kind of hydraulic fracture sand flushing device, including top connection 1；It is set in 1 inside limiting slot of top connection
There is rotation assembly 2,2 lower end of rotation assembly connects central tube 5, ball-and-seat 3 is equipped on central tube 5, it is total that central tube 5 passes through transmission
At 4, drive assembly 4 is connected to 1 lower end of top connection, and 5 lower end of central tube connects hollow scraper 6, is provided with hydrophthalmia on hollow scraper 6,
Design has single flow channel on 2 lower end inner cavity of rotation assembly, and 4 lower end inner cavity of drive assembly is equipped with single flow channel, and liquid is total from rotation
4 internal rotating blade of drive assembly is passed at the single flow channel on 2 inner cavities to flow out to from 4 lower end single flow channel of drive assembly
Inside central tube 5, liquid is able to drive rotating vane rotation, rotating vane rotation when flowing through 4 internal rotating blade of drive assembly
It is able to drive the rotation of central tube 5.
In use, 1 upper end screwed connection sand-flushing pipe column of top connection, when inverse circular sand washing adapter, liquid is taken sand flow and is scraped from hollow
Hydrophthalmia flows through central tube 5 in knife 6, opens ball-and-seat 3, is returned out into oil pipe by well head.
When direct circulation is crushed, high pressure water is entered by top, and because ball-and-seat 3 is arranged at 5 top of central tube, high pressure water can only be flowed through
2 inner cavity single flow channel of rotation assembly, impact rotating vane generate rotation torque, and rotating vane drives central tube 5 rotating, in turn
It drives hollow scraper 6 to rotate, broken drilling is carried out to hollow 6 lower part sand face of scraper.Rotation assembly 2 uses bearing, and central tube 5 revolves
When turning, top connection 1 is not rotated with central tube 5.
It is understood that being merely to illustrate the utility model above with respect to the specific descriptions of the utility model and not being
It is limited to technical solution described in the utility model embodiment, those skilled in the art should understand that, it still can be with
It modifies to the utility model or equivalent replacement, to reach identical technical effect；Needs are used as long as meeting, all in this reality
Within novel protection scope.
