The utility model provides a kind of sand flushing tool, as shown in Figure 1, including tubular body 1 and baffle 2, wherein tubulose
Connecting plate 3 and the baffle ring 4 positioned at 3 lower section of connecting plate are provided on the inner wall of ontology 1；One end of connecting plate 3 connects with baffle 2
It connects；Liquid pass hole 201 is provided on baffle 2；Baffle 2 is configured as the upper of in the nature edge of its lower face and baffle ring 4
End face is bonded, and is rotated up relative to connecting plate 3 when by upward active force and is detached with baffle ring 4.
It is understood that the gap after under 1 lower going-into-well of tubular body between casing passes through convenient for sand cleaning fluid.
The operation principle for the sand flushing tool that the utility model embodiment provides is as described below：
It is lowered into casing after the upper end of tubular body 1 is connect with sand-flushing pipe column, until the lower end of tubular body 1 reaches
Artificial bottom of a well or predetermined depth.
When carrying out positive sand washing, sand cleaning fluid is pumped into the inner cavity of sand-flushing pipe column, sand cleaning fluid is made quickly to move down, entered
After in tubular body 1, by the liquid pass hole 201 on baffle 2, it is discharged later from the bottom end of tubular body 1, by the sand setting of underground
It breaks up, so that the sand setting broken up and sand cleaning fluid is mixed to form mulling solution, and along sand-flushing pipe column and the annular space of casing formation under
Ground is drained on and.
When carrying out anti-sand washing operation, sand cleaning fluid is pumped into the annular space that sand-flushing pipe column is formed with casing, keeps sand cleaning fluid fast
Speed moves down, and the sand setting of underground is broken up, and so that the sand setting broken up and sand cleaning fluid is mixed to form mulling solution, and enter pipe
In shape ontology 1, mulling solution applies baffle 2 upward active force, and baffle 2 is made to be detached with baffle ring 4, and then tubular body 1
Inner cavity is connected to up and down, and mulling liquid is entered by tubular body 1 in sand-flushing pipe column, drains into ground from bottom to top.
Wherein, the structure of tubular body 1 can be a variety of, for example, can be hollow cylindrical structure, hollow round table
Shape structure etc..
The sand cleaning fluid used when carrying out sand washing operation refers to the liquid for releasing sand plug, currently used sand cleaning fluid class
Type has oil, water, emulsion and vaporization liquid etc..
In sand flushing tool provided by the utility model, by being provided with connecting plate 3 and position on the inner wall of tubular body 1
Baffle ring 4 in 3 lower section of connecting plate, one end of connecting plate 3 is connected with baffle 2, liquid pass hole 201, and baffle 2 is provided on baffle 2
It is configured as the lower face at its edge in nature to be bonded with the upper surface of baffle ring 4, to be flowed into 1 inner cavity of tubular body
In sand cleaning fluid increased by speed after liquid pass hole 201, when being discharged from the bottom end of tubular body 1 to the impact force of shaft bottom sand setting compared with
Greatly, sand washing effect is improved；When one end by the way that connecting plate 3 is arranged is connect with baffle 2 and baffle 2 is by upward active force
It is rotated up relative to connecting plate 3 and is detached with baffle ring 4, then enter the mulling liquid in tubular body 1 when carrying out recoil sand
Apply upward active force when flowing up to baffle 2, baffle 2 is made to be detached with baffle ring 4, to which mulling liquid passes through tubular body 1
It enters in sand-flushing pipe column, and drains into ground from bottom to top.
In the utility model embodiment, as shown in Figure 1, the lower end of tubular body 1 is a pointed ends 101.
Wherein, the connection type between tubular body 1 and pointed ends 101 can there are many, for example, the two can
To link together by welding, directly the two can also be processed as one.
So set, keep the bottom of sand flushing tool pointed, and positioned at the outside of tubular body 1, when tripping in sand flushing tool
Shi Jineng breaks up some unsubstantial sand settings, and can prevent from making drifting tubing string lowering velocity is too fast to cause to suppress pump because of maloperation,
If the bottom of sand washing head 2 is not pointed but planar, when drifting tubing string lowering velocity is too fast encounters underground sand setting, sand setting
It is easy to block the planar bottom end of sand washing head 2, in turn results in and suppress pump.It is understood that the shape class of pointed ends 101
It is similar to the shape of the pen tip of common pen, downward, the shape in section is right angled triangle for tip.
The realization method that one end as connecting plate 3 is rotatably connected with baffle 2, one end and the baffle 2 of connecting plate 3 can lead to
Linear bearing connection is crossed, or is connected through the hinge.
Connect with sand-flushing pipe column for the ease of tubular body 1, as shown in Figure 1, the upper end of tubular body 1 be connected with in it
The top connection 5 that chamber is connected.
The mode that top connection 5 is connect with tubular body 1 can be welding, or be detachably connected.It is preferred that being detachably connected, just
It is dismantled in the two.There are many modes being detachably connected, the mode being preferably threadedly coupled, such as 5 side of being threadedly coupled of top connection
Formula is set in outside 1 upper end of tubular body.
So set, ensure that top connection 5 connect fastening with tubular body 1, at the same it is easy to disassemble, needing replacing sand washing
It is very convenient when tool.Wherein, it is provided with external screw thread on the outer wall of 1 upper end of tubular body, is arranged on the inner wall of 5 lower end of top connection
There is internal thread compatible with the external screw thread.
In the utility model embodiment, internal thread is provided on the inner wall of 5 upper end of top connection；Wherein, under sand-flushing pipe column
External screw thread compatible with the internal thread is provided on the outer wall at end, top connection 5 is threadedly coupled with drifting tubing string.It ensure that and connect
First 5 tightness being connect with sand-flushing pipe column, it is very convenient when sand-flushing pipe column lower end installs or removes top connection 5.
In the utility model embodiment, the diameter of liquid pass hole 201 can be 12-20mm, preferably 17mm.
The speed so set, size of liquid pass hole 201 not only passed through convenient for sand cleaning fluid, but also after sand cleaning fluid being made to pass through compared with
Greatly.When the diameter of liquid pass hole 201 is smaller, sand cleaning fluid by flow it is too small, influence the efficiency of sand washing；And work as liquid pass hole 201
Diameter it is too big when, sand cleaning fluid is not big enough by rear speed, not big enough to the impact force of shaft bottom sand setting, and sand washing effect is bad.
In the present embodiment, the thickness of baffle 2 can be 2-4mm, preferably 3mm.
So set, both can guarantee the robustness of baffle 2, the sand cleaning fluid to flow downward is avoided to damage the impulse force of baffle 2
Baffle 2, and the thickness that can avoid baffle 2 causes greatly its weight larger very much, and cause the mulling liquid flowed up cannot smoothly by
The case where baffle 2 jacks up.
In the present embodiment, the total length of sand flushing tool can be 450-550mm, preferably 500mm.
By setting the length of tubular body 1 to 500mm, it ensure that tubular body 1 has certain length, be lowered into
Detection casing can be assisted after in casing, and whether there is or not deformations.
It should be noted that the total length of the diameter of liquid pass hole 201, the thickness of baffle 2 and sand flushing tool is not limited to
Range is stated, can be determined according to actual condition.
In this application, it should be understood that term " first ", " second " etc. are used for description purposes only, and should not be understood as
It indicates or implies relative importance or implicitly indicate the quantity of indicated technical characteristic.
The above is merely for convenience of it will be understood by those skilled in the art that the technical solution of the utility model, not to
Limit the utility model.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on,
It should be included within the scope of protection of this utility model.
