Abstract
A kind of underground is logical to scrape integration tool string, including joint, and mandrel, drifting pipe nipple, scraper is primarily characterized in that：The mandrel segmentation is provided with external screw thread, and the drifting pipe nipple and scraper inner walls are provided with internal thread, and drifting pipe nipple and scraper are linked together by mandrel, and drifting pipe nipple is arranged on the bottom of scraper；The body portion of the scraper is also secured on mandrel, and is stretched out outside the housing of scraper；The blade lengths of the body portion differ, and bottom is shortened cutting blade, is up lengthened successively, generally form inverted trapezoidal structure set of blades.The utility model provide it is a kind of be applied to that hole deviation is big, underground the oil well of sleeve pipe slight bending, lead to and scrape integration tool string.
Description
Technical field
The utility model is related to oil exploration equipment field, more particularly to a kind of underground is logical scrapes integration tool string.
Background technology
With the increase of producing well working time, oil well well workover number of times increases year by year, and drifting process and scraping process are two
The process for plowing complete independently, is typically supported the use（First drifting scraping again）, and both processes most service shafts with
And using more in partial maintenance operation well.In the prior art, by drifting scraping integrated tool, by original work twice
Sequence becomes one time to complete, and so both saves operating cost, can shorten accounting for the well cycle again, but existing drifting scraping is integral
Change tool length longer, be not suitable for hole deviation is big, use in the well of sleeve pipe slight bending, easy card tubing string.
Utility model content
The purpose of this utility model is to scrape integration tool string in view of the deficienciess of the prior art, providing a kind of underground and leading to.
Technical scheme：The utility model solve the technical scheme that is used of problem for：A kind of underground is logical to scrape integration tool string,
Including joint, mandrel, drifting pipe nipple, scraper is primarily characterized in that：The mandrel segmentation is provided with external screw thread, the drifting
Pipe nipple and scraper inner walls are provided with internal thread, and drifting pipe nipple and scraper are linked together by mandrel, and drifting pipe nipple is set
Put in the bottom of scraper；The body portion of the scraper is also secured on mandrel, and is stretched out outside the housing of scraper.
Wherein, the blade lengths of the body portion differ, and bottom is shortened cutting blade, is up lengthened successively, is generally formed
Inverted trapezoidal structure set of blades.
Wherein, the blade edge of the set of blades is zigzag.
Wherein, the external diameter of drifting pipe nipple is less than the external diameter at scraper most shortened cutting blade.
Wherein, the length of drifting pipe nipple is 80mm.
Beneficial effect：The utility model has the advantages that：Drifting pipe nipple length of the present utility model is far below general
Logical gauguste cutter, it is adaptable to which hole deviation is big, in the oil well of sleeve pipe slight bending, is difficult to cause due to the impurity jam pipe that scraping is produced
The phenomenon of post；The set of blades of inverted trapezoidal structure, shortened cutting blade first carries out pre- pipe cleaning, reduces the thickness of the dirty block of tube wall, long blade is immediately
And carry out pipe cleaning again, improve the operating efficiency of scraping tube wall；The drifting scraping activity duration, operating cost was significantly than original reduction
Reduction, has reached the effect produced in crude oil volume increase, is further raising oil-water well operation technology, shortens duty cycle, lifting is made
Industry quality and operation effectiveness.
Brief description of the drawings
Fig. 1 is the utility model structure chart.
Embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the utility model is further elucidated, the present embodiment is with the utility model
It is lower premised on technical scheme to be implemented, it should be understood that these embodiments are merely to illustrate the utility model rather than limit this reality
With new scope.
As shown in figure 1, a kind of underground, which leads to, scrapes integration tool string, including joint 1, and mandrel 2, drifting pipe nipple 3, scraper 4, its
It is characterized mainly in that：The segmentation of mandrel 2 is provided with external screw thread, and drifting pipe nipple 3 and scraper 4 inner walls are provided with interior spiral shell
Line, drifting pipe nipple 3 and scraper 4 are linked together by mandrel, and drifting pipe nipple 3 is arranged on the bottom of scraper 4；The shaving
The body portion of device 4 is also secured on mandrel 2, and is stretched out outside the housing of scraper 4.
Wherein, the blade lengths of the body portion differ, and bottom is shortened cutting blade 5, up lengthens, generally forms successively
Inverted trapezoidal structure set of blades.
Wherein, the blade edge of the set of blades is zigzag.
Wherein, the external diameter of drifting pipe nipple 3 is less than the external diameter at the most shortened cutting blade 5 of scraper 4.
Wherein, the length of drifting pipe nipple 3 is 80mm.
Drifting pipe nipple length of the present utility model is far below common gauguste cutter, it is adaptable to which hole deviation is big, sleeve pipe slight bending
Oil well in, be difficult to cause due to the phenomenon for the impurity jam tubing string that scraping is produced；The set of blades of inverted trapezoidal structure, shortened cutting blade is first
Pre- pipe cleaning is carried out, reduces the thickness of the dirty block of tube wall, and then long blade carries out pipe cleaning again, the work effect of scraping tube wall is improved
Rate；The drifting scraping activity duration substantially reduces than original reduction, operating cost, the effect produced in crude oil volume increase has been reached, to enter
One step improves oil-water well operation technology, shortens duty cycle, lifting operation quality and operation effectiveness.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art
For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and
Retouching also should be regarded as protection domain of the present utility model.
