Specific embodiment
To make technical scheme of the present invention and advantage clearer, embodiment of the present invention is made below in conjunction with attached drawing into
One step it is described in detail.
An embodiment of the present invention provides a kind of down-hole oil tube siphunculus tool, as shown in Figure 1, it includes becoming buckle joint 2, aggravate
Bar 3, limited cap 4, mandrel 5 and scraping head 6.
Specifically, scraping head 6 is internally provided with cavity, and the lower part for becoming buckle joint 2 is connected with the top of weighted lever 3, add
The lower part of weight bar 3 is connected with the top of mandrel 5, and limited cap 4 is set on the outer wall of mandrel 5, lower part and the scraping head of limited cap 4
6 top is connected, and mandrel 5 is adapted for insertion into the cavity of scraping head 6, and mandrel 5 can relative rotation and axial position with scraping head 6
It moves.
Therefore, the present invention is internally provided with cavity using scraping head 6, and mandrel 5 is adapted for insertion into the cavity of scraping head 6
In, mandrel 5 and scraping head 6 can relative rotation and axial displacement, jarring and rotational shear pipe can be realized by extraction tool repeatedly
The viscous crude effect assembled in column, realizes the unimpeded of tubing string.
As the further improvement to the present embodiment, which further includes wire rope socket 1, steel wire rope
The lower part of cap 1 is connected with becoming the top of buckle joint 2 by screw thread；The down-hole oil tube siphunculus tool further includes the first pin 7, and first
Pin 7, which passes through, becomes buckle joint 2, and one end, which is exposed, to be become outside the outer wall of buckle joint 2, and the other end is connected with weighted lever 3, solid for connecting
Surely become buckle joint 2 and weighted lever 3；The down-hole oil tube siphunculus tool further includes the second pin 8, and the second pin 8 passes through weighted lever 3,
One end is leaked out outside the outer wall of weighted lever 3, and the other end is connected with mandrel 5, for connecting fixed weighted lever 3 and mandrel 5；The underground
Oil pipe siphunculus tool further includes third pin 9, and third pin 9 passes through scraping head 6, and one end is leaked out outside the outer wall of scraping head 6, separately

Scraping head 6 and limited cap 4.
Meanwhile as shown in Fig. 2, scraping head 6 lower part for cone, scraping head 6 is facilitated to be lowered into tubing string, in scraping head
6 outer wall, which is laid with spiral, to be scraped and chips, and scraping head 6 is driven for scraping to chip by spiral under the action of the water in pit shaft and oil stream
Rotation, realizes the scraping to viscous crude in tubing string；The lower part outer wall of mandrel 5 is provided with protrusion, it should be noted that protrusion is in Fig. 1
In do not specifically give, protrusion cannot be by limited cap 4, for limiting motion range of the mandrel 5 in scraping head 6.
In actual use, the tool is lowered into the separate injection tubing string of underground by 10 connecting steel wire ropes cap 1 of steel wire,
Using the Gravitative Loads of tool, scraping head 6 is made to be inserted into viscous crude and blocks well section, by water in tubing string and oil stream to the work of scraping head 6
With, scraping head 6 generates rotation, and spiral is made to scrape scraping tube wall of chipping, meanwhile, scraping head 6 can relative rotation and axial position with mandrel 5
It moves, when scraping head 6 is hampered, mandrel 5 and weighted lever 3 continue traveling downwardly jarring scraping head 6, during extraction tool repeatedly, lead to
It crosses the jarring of tool and rotational shear crushes the viscous crude assembled in tubing string, realize de-plugging purpose.
The down-hole oil tube siphunculus tool of the present invention, including becoming buckle joint, weighted lever, limited cap, mandrel and scraping head, scraping
Head is internally provided with cavity, and mandrel is adapted for insertion into the cavity of scraping head, and mandrel can relative rotation and axial direction with scraping head
Displacement, on the one hand, using mandrel and scraping head can relative rotation and axial displacement, by extraction tool repeatedly can realize jarring and
The viscous crude effect assembled in rotational shear tubing string, realizes the unimpeded of tubing string；On the other hand, by water in pit shaft and oil stream to scraping
The active force of head rotates scraping head, realizes the scraping to viscous crude in tubing string, and inventive structure is simple, reduces appearance during de-plugging
The incidence of failure, and when tool is when meeting card during upper carry can lift the method for tool by work by anti-flushing well and repeatedly
Tool proposes that reduction tool falls the risk of well out of well.
The above is for only for ease of it will be understood by those skilled in the art that technical scheme of the present invention, not limiting
The present invention.All within the spirits and principles of the present invention, any modification, equivalent replacement, improvement and so on should be included in this
Within the protection domain of invention.
