The descaling tool of two kinds of structure type, and according to the prior art, when being used alternatingly, two kinds can only be transferred respectively by tubing string twice
Descaling tool causes scale removal operation process cumbersome, and operating efficiency is low, and operating cost is high.
Invention content
The utility model provides a kind of diameter of axle one reciprocating descaling spray gun, to solve mentioned above in the background art ask
Topic.
The technical issues of the utility model is solved is realized using following technical scheme：The utility model provides one kind
Diameter of axle one reciprocating descaling spray gun, including the body of a gun and pipette tips, the pipette tips are connected to the lower end of the body of a gun, the rifle by short circuit
End surface is provided centrally with circular hole, and axial nozzle is evenly distributed with around the circular hole, is arranged on the side wall of the body of a gun
There are radial nozzles, piston is provided in the body of a gun, one end of piston, which is inserted in the short circuit and is sealed with short circuit, to be coordinated, piston
The other end is inserted in the circular hole of body of a gun end and coordinates with the inner wall sealing of the circular hole, and the side of upper piston area was provided with liquid
Hole, liquid pass hole are located at the sealing cooperation section of piston and the body of a gun or more, spring are housed, one end of spring is limited in the short circuit
System is against in the junction of pipette tips and short circuit, the other end of spring on the end face of the piston.
The axial nozzle at least there are three.The radial nozzles share six groups, and every group is total to there are three radial nozzles,
Six groups of radial nozzles equidistantly arrange in an axial direction.
The beneficial effects of the utility model are：The utility model is by the waterpower scale removal of two kinds of structure type in the prior art
Tool is combined into one, and by putting into different size of ball to well head, can be realized in the case where only transferring one-trip string axial
The alternating of scale removal and radial scale removal improves operating efficiency to simplify operation process, reduces operating cost.In addition, axis
Diameter scale removal alternately, is relatively carried out at the same time the power input that can reduce pump, reduces the power demand to equipment, can make the suitable of technology
It is broader with range.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
In figure, 1- axial direction nozzles, 2- beads, 3- pipette tips, 4- springs, 5- short circuits, the big balls of 6-, 7- radial nozzles, the 8- body of a guies,
9- pistons, 10- liquid pass holes.
Specific implementation mode
The utility model is described further below in conjunction with attached drawing：
The present embodiment includes the body of a gun 8 and pipette tips 3, and the pipette tips 3 are connected to the lower end of the body of a gun 8, the rifle by short circuit 5
First 3 end face is provided centrally with circular hole, and axial nozzle 1 is evenly distributed with around the circular hole, is set on the side wall of the body of a gun 8
Radial nozzles 7 are equipped with, piston 9 is provided in the body of a gun 8, one end of piston 9 is inserted in the short circuit 5 and matches with the sealing of short circuit 5
It closes, the other end of piston 9 is inserted in the circular hole of 8 end of the body of a gun and coordinates with the inner wall sealing of the circular hole, the side on 9 top of piston
It is provided with liquid pass hole 10, liquid pass hole 10 is located at piston 9 with more than the sealing cooperation section of the body of a gun 8, bullet is housed in the short circuit 5
Spring 4, one end of spring 4 are limited in the junction of pipette tips 3 and short circuit 4, and the other end of spring 4 is against the end of the piston 9
On face.
The axial nozzle 1 at least there are three.
The radial nozzles 7 share six groups, and every group there are three radial nozzles 7 altogether, between six groups of radial nozzles 7 wait in an axial direction
Away from arrangement.
It is using the step of the utility model progress scale removal：
1, by scale removal tubing string lower going-into-well, tubing string is hampered, and illustrates to encounter fouling.
2, big ball 6 is put into, big ball 6 is by the passage plugging in 9 center of piston, to cut off 9 part below of piston, axial spray
Mouth 1 and radial nozzles 7 are all blocked.
3, forward direction is suppressed, and oily overpressure increases, and piston 9 overcomes the resistance of spring 4 to move down, the mistake on piston 9
When fluid apertures 10 is moved to the sealing section between piston 9 and the body of a gun 8 or less, water by liquid pass hole 10 enter piston 9 and the body of a gun 8 it
Between annular space, then sprayed by radial nozzles 7, realize radial scale removal.If (fouling is not serious, can scale removal always to shaft bottom)
4, Downhole jetting but no drilling depth are carried out, illustrates that wellbore fouling is more, wellbore is small, and descaling tool is blocked, at this time into
Big ball 6 is recycled to ground and taken out by row anti-flushing well, meanwhile, piston 9 returns to original position under the action of spring 4, again by radial spray
Mouth 7 blocks.
5, bead 2 is put into, bead blocks the circular hole in 3 center of pipette tips after entering in pipette tips 3, and high pressure water is from axial nozzle 1
It sprays, realizes axial scale removal.
6, when tubing string is hampered, stop scale removal, anti-flushing well washes out bead 2.
7, upper lifting pipe post to last time is hampered position, constructs by step 2,3.
8, scale removal is hampered again, constructs by step 4,5,6.
9, scale removal terminates anti-flushing well, washes out all dirty in well consider to be worth doing.
10, it rises and scale removal tubing string.
Can have been found out by above-mentioned operation process, the utility model not only can to axial nozzle 1 and radial nozzles 7 into
Row switching, and two kinds of nozzles can work independently so that and the utility model can fully merge the advantages of two kinds of descaling tools,
And then scale removal effect is fully ensured that while convenient working.
In conclusion the waterpower descaling tool of two kinds of structure type in the prior art is combined into one by the utility model,
Structure novel, it is ingenious in design, by putting into different size of ball to well head, can be realized in the case where only transferring one-trip string
The alternating of axial scale removal and radial scale removal improves operating efficiency to simplify operation process, reduces operating cost.Separately
Outside, diameter of axle scale removal alternately, is relatively carried out at the same time the power input that can reduce pump, reduces the power demand to equipment, can make skill
The scope of application of art is broader.
