Abstract
A kind of axial vibration crawl device, it includes body, pin thread and box, and the body outer surface is longitudinally uniformly provided with 4 10 equal-sized annular tooths, equal-sized thin sand launder is equipped between every annular tooth；Each annular tooth section is right angled triangle, and right angle one, facing to box side, first annular tooth section by box side is double inclined plane.The present invention is simple in construction, can prevent drill string reverse movement and prevent the accumulation of landwaste.
Description
Technical field
The invention belongs to field of mechanical technique, more particularly to a kind of oil gas well drilling instrument.
Background technology
The exploration and development technology of the complicated casing programme well such as horizontal well, extended reach well is more and more ripe in recent years.Due to well
The problems such as oblique angle is larger, pit shaft fluid column and stratum form larger pressure difference, talus deposit so that the frictional resistance of drill string is larger, makes
It is obstructed into load transfer, rate of penetration reduces and drill string, the problems such as casing wear is serious.Domestic and international experts and scholars develop shaft
To vibration antifriction tool, drill string produces axial vibration by a small margin, is changed into the static friction between drill string and the borehole wall in the axial direction
Dynamic friction, Value of Friction Loss can be effectively reduced.
But when axial vibration generator works, some active force points to drill bit direction, can make BHA
Advance by a small margin is produced, fraction the pressure of the drill is provided to drill bit.Active force of the another part away from drill bit direction can make drill set
The retroversion produced by a small margin is closed, influences drilling efficiency.
The content of the invention
It is an object of the invention to provide a kind of axial vibration crawl device that can prevent drill string reverse movement.
Technical scheme is as follows：
The present invention includes body, pin thread and box, wherein, it is equal-sized that body outer surface is longitudinally uniformly provided with 4-10 bars
Annular tooth, equal-sized thin sand launder is equipped between every annular tooth；Each annular tooth section is right angled triangle, and directly
Facing to box side, first annular tooth section by box side is double inclined plane at angle one.
In use, the pin thread or box of axial vibration crawl device are connected with axial vibration generator, when axial vibration occurs
When device drive drill string does the axial vibration opposite with drilling direction in pit shaft, the ring-like tooth group of axial vibration crawl device outer surface
Right angle side contacts with the borehole wall, and resistance is larger, can effectively prevent the reverse movement of whole drill string.Conversely, vibrated to drilling direction
When annular tooth inclined-plane contacted with the borehole wall, resistance is small, can smoothly advance.Thin sand launder in annular tooth group can prevent the accumulation of landwaste,
The double inclined plane annular tooth of adjacent box side can facilitate drill string to remove.
The present invention has the following advantages that compared with prior art：
(1) it is simple in construction；
(2) prevent drill string reverse movement and prevent the accumulation of landwaste.
Brief description of the drawings
Fig. 1 is the structural representation part figure of the present invention.
In figure：1- boxes, 2- bodies, 3- annular tooths, 4- pin threads, 5- dredge sand launder, 6- double inclined plane annular tooths.
Embodiment
In the axial vibration crawl device schematic diagram shown in Fig. 1, one end of body 2 is connected with box 1, the body it is another
End is connected with pin thread 4, and the outer surface of body is axially uniformly provided with 6 equal-sized annular tooths 3, is all provided between every annular tooth
There is equal-sized thin sand launder 5；Each annular tooth section is right angled triangle, and right angle one is facing to box side, by mother
First section of annular tooth 6 for detaining side is double inclined plane.
This instrument is connected by screw thread with axial vibration generator, should be according to specific operating mode, selective use.
