The screen is arranged on the lower sides of the guide pipes. The one-way valve is arranged at the bottom of the body. According to the vacuum suction pitshaft fishing and cleaning tool, negative pressure is formed in the tool based on the Venturi principle, fluid mixed with dropping matter and debris is sucked into the body, and fishing is completed; the fishing effect is good, and efficiency is high.
Description
Technical field
The present invention relates to petroleum drilling well workover field, particularly relate to a kind of vacuum draw pit shaft salvaging, fettler
Tool.
Background technology
During drilling well and workover treatment, down-hole often can produce a large amount of loose junk and chip etc., and this needs clear
Reason is clean, to ensure lower step operation normal construction.Due to loose junk and chip etc. often have volume little,
The physical characteristics such as density is high, quantity is many, big to its difficulty salvaged, conventional fishing tool is to this kind
Junk need to enter well and repeatedly salvage, but effect is the most not fully up to expectations；Drilling and repairing well operation certainly will be increased
The risk and cost.
Summary of the invention
In order to solve above-mentioned technical problem, the present invention provides a kind of vacuum draw pit shaft to salvage, cleaning tool,
Utilize venturi principle to form negative pressure in device, the fluid being mixed with junk and chip be drawn into internal,
Completing to salvage, salvage effective, efficiency is high.
To this end, technical program of the present invention lies in:
A kind of vacuum draw pit shaft is salvaged, cleaning tool, including the body that can connect as one with drilling tool and
It is set in turn in the nozzle carrier of body interior, guide pipe, screen cloth and check valve；Described body is tubular；Institute
State nozzle carrier to be fixedly installed on described body medial wall；One or more nozzle it is provided with on described nozzle carrier,
Each nozzle all with the bottom surface out of plumb of described nozzle carrier；It is fixedly installed one on the downside of corresponding described nozzle carrier
Individual or multiple guide pipes, the diameter of described guide pipe is more than the diameter of described nozzle, and in each guide pipe
Axis overlaps with the extended line of the axis of described nozzle；Described screen cloth is arranged at the downside of described guide pipe；
Described check valve is arranged at described body bottom portion.
Further, described nozzle and guide pipe are provided with spacing in the vertical.
Further, when described nozzle is multiple, it is uniformly distributed along described nozzle carrier circumference；Lead described in Dui Ying
Have to pipe multiple, be uniformly arranged along described body circumference.Further, described nozzle is provided with 2～5, right
The described guide pipe answered is provided with 2～5.
Further, described body bottom is also equipped with milling shoe.
Further, described body is additionally provided with Magnet.
Further, described body is additionally provided with scrapes tube brush.
Further, described body is assembled into one by fixing device by two semi-circular tubes.This fixing device can
Think ring-type buckle, it is also possible to be bridge joint hasp.The convenient dismounting of body, it is simple to internal salvaging bits clear out.
By on-the-spot actual application, this vacuum draw pit shaft is salvaged, cleaning tool has the advantage that
1. fishing can disposably be completed, effective；
2. its position in tubing string can arbitrarily be adjusted；Salvaging the capacity of chip as required, regulation increases this
The length (oil pipe or milling pipe) of body, the ability salvaging junk is big；
3. multiple fishing tool can be coordinated to be used together, expanded its scope salvaged, reduced and salvage number of times.
Accompanying drawing explanation
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the use state diagram of the present invention.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, technical scheme is described in detail.
As it is shown in figure 1, a kind of vacuum draw pit shaft is salvaged, cleaning tool, body 4 is tubular, its top
It is provided with the screw thread mated with drilling tool, is connected as one with drilling tool by screw thread；Body 4 is internal to be depended on from top to bottom
Secondary it is provided with nozzle carrier 1, guide pipe 3, screen cloth 5 and check valve 6；Nozzle carrier 1 is fixedly installed on body 4
On medial wall, being provided with one or more nozzle 2, does not hangs down in each nozzle 2 all bottom surfaces with nozzle carrier 1
Directly；Being fixedly installed one or more guide pipe 3 on the downside of corresponding nozzle carrier 1, the diameter of guide pipe 3 is more than
The diameter of nozzle 2, and the axis of each guide pipe 3 overlaps with the extended line of the axis of nozzle 2；Sieve
Net 5 is arranged at the downside of guide pipe 3；Check valve 6 is arranged at bottom body 4.
Venturi effect show restricted flow when by the flow section that reduces, fluid occurs that flow velocity increases
Phenomenon, its flow velocity is inversely proportional to flow section.And learnt that the increase of flow velocity is with fluid by Bernoulli's theorem
The reduction of pressure, can produce low pressure near swiftly flowing fluid, forms vacuum area, generates therefrom
Pressure differential there is strong adsorption effect.
During use, as in figure 2 it is shown, fluid pumps on the upside of body, when flowing through at nozzle 2, disconnected owing to crossing stream
Face reduces, and rate of flow of fluid increases, and forms vacuum area, flow out from nozzle 2 meanwhile on the downside of nozzle carrier 1
Fluid inject guide pipe 3, and flow through guide pipe 3 and enter the annular region between body 4 and pit shaft；Part
Fluid is downward, takes the junk in pit shaft and chip arrives the salvaging of this vacuum draw pit shaft, the bottom of cleaning tool,
Owing to now its body 4 chamber pressure is less than external pressure, the fluid taking the junk in pit shaft and chip is pushed open
It is internal that check valve enters body 4, the most upwards filters through screen cloth 5, and junk and chip are inside body 4；
Liquid enters the position between nozzle carrier 1 and screen cloth, then flows into guide pipe 3, forms circulation (such as arrow in figure
Shown in head).After termination of pumping, closed check valve, junk and chip are fixed on body 4 internal, it is to avoid again fall
Go back to shaft bottom, then pull out of hole, open body, cleaning, complete fishing.
As one embodiment of the present of invention, there is gap, in other words in nozzle 2 and guide pipe 3 in the vertical
Saying, nozzle 2 is not partially inserted into inside guide pipe.
Preferably, nozzle 2 is provided with 2～5, and corresponding guide pipe 3 is provided with 2～5.It is further preferred that nozzle 2
For time multiple, it is uniformly distributed along nozzle carrier 1 circumference；Corresponding guide pipe 3 has multiple, along body 4 circumference
It is uniformly arranged.
As an improvement project of the present invention, body 4 bottom is also equipped with milling shoe 7.Milling shoe is used for protecting this
Body 4 is not damaged by during going into the well.
As an improvement project of the present invention, body 4 is additionally provided with Magnet.It is domestic heavy to salvage simultaneously
Iron filings in sand.
As an improvement project of the present invention, body 4 is additionally provided with and scrapes tube brush, be used for clearing up pit shaft.
As an improvement project of the present invention, body 4 is assembled into one by two semi-circular tubes by fixing device
Body.
