Abstract
The utility model relates to a wear -resisting chip removal drill collar, including drill collar body, wear -resisting dish and male joint, wear -resisting dish is all installed at drill collar body both ends, wear -resisting dish includes wear -resisting area, spiral groove and buffering area, the strip groove of spiral groove for offering on the disc outside wear -resisting dish, other parts are wear -resisting area on the outer disc of wear -resisting dish, and the buffering area sets up in between wear -resisting dish and drill collar body for convex structure, the male joint sets up in drill collar body right -hand member. The utility model discloses a set up wear -resisting dish, let the drill collar body in the pit not with wall of a well direct contact, reducing wear, set up spiral groove on the wear -resisting dish, the detritus can upwards be discharged through it, reduce the drill collar sticking of tool, wear -resisting dish is detachable construction simultaneously, in case wearing and tearing are too serious, removable new wear -resisting dish reduces the wasting of resources rather than whole drill collar, practices thrift drill collar manufacturing cost, reduces and changes the degree of difficulty.
Description
Technical field
This utility model relates to a kind of oil drilling tool, particularly to a kind of wear-resisting chip removal drill collar.
Background technology
Drill collar, is in the foot of drill string, is the key component of bottomhole assembly.It is big that it is mainly characterized by wall thickness, and one
As be 4 to 6 times of drill pipe thickness, there is bigger gravity and rigidity.Drilling process acts primarily as the effect of following several respects:
1, the pressure of the drill is applied to drill bit；2, alleviate the vibration of drill bit, swing and beat, make bit operation steady.
Along with the continuous exploitation of oil, it has also been found that following problem during drill collar uses: drill collar and the borehole wall when using common drill collar
Friction is relatively big, and the power being applied to drill bit consumes the biggest in drilling process；Landwaste easily deposits, and causes drill collar or heavy weight drill pipe
Dry grind with the borehole wall and form bit freezing.And drill collar is relatively costly, once damages and be difficult to repair, causing waste greatly.
Utility model content
For the problems referred to above, the purpose of this utility model is the deficiency overcoming prior art to exist, it is provided that one can reduce drill collar
Abrasion, discharges the drill collar of landwaste the most smoothly.
The technical solution of the utility model is achieved in that
A kind of wear-resisting chip removal drill collar, including drill collar body, Wear resistance disk and male joint；Described drill collar body two ends are mounted on wear-resisting
Dish；Described Wear resistance disk includes wear-resistant strip, helical groove and buffer strip；Helical groove is the strip offered on Wear resistance disk periphery
Groove, on Wear resistance disk periphery, other parts are wear-resistant strip, and buffer strip is arc-shaped structure, are arranged at Wear resistance disk and drill collar body
Between；Male joint is arranged at drill collar body right-hand member.
Further, bigger than this body diameter of drill collar 1/2 inch of described Wear resistance disk external diameter.
Further, described Wear resistance disk uses and is threaded on drill collar body.
Further, described helical groove quantity is 3 to 8.
Further, described helical groove bottom is provided with rounding, reduces landwaste and is detained.
Further, described helical groove is dextrorotation.
The utility model has the advantage of:
1, by arranging Wear resistance disk, allow drill collar body directly not contact with the borehole wall in down-hole, reduce abrasion；
2, on Wear resistance disk, helical groove is set, landwaste upwards can be discharged by it, reduces drill collar bit freezing；
3, Wear resistance disk is demountable structure, once weares and teares excessively serious, and replaceable new Wear resistance disk rather than whole drill collar reduce
The wasting of resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is structural representation left view of the present utility model；
In figure: 1 is drill collar body, 2 is Wear resistance disk, and 2-1 is helical groove, and 2-2 is wear-resistant strip, and 2-3 is buffer strip, and 3 are
Male joint.
Detailed description of the invention
The utility model is described in further detail for embodiment in below in conjunction with the accompanying drawings, but is not intended that this utility model
Any restriction.
As shown in Figure 1 and Figure 2, a kind of wear-resisting chip removal drill collar, including drill collar body 1, Wear resistance disk 2 and male joint 3；Described brill
Quickly body 1 two ends are mounted on Wear resistance disk 2；Described Wear resistance disk 2 includes wear-resistant strip 2-2, helical groove 2-1 and buffer strip 2-3；
Described helical groove 2-1 is the strip slot offered on Wear resistance disk 2 periphery, and helical groove 2-1 quantity is 3 to 8, spiral shell
Rotation groove 2-1 bottom is provided with rounding, reduces landwaste and is detained, and helical groove 2-1 is other portions on dextrorotation Wear resistance disk 2 periphery
Being divided into wear-resistant strip 2-2, buffer strip 2-3 is arc-shaped structure, is arranged between Wear resistance disk 2 and drill collar body 1；Male joint 3
It is arranged at drill collar body 1 right-hand member；Bigger than drill collar body 1 external diameter 1/2 inch of described Wear resistance disk 2 external diameter；Wear resistance disk 2 uses spiral shell
Stricture of vagina is connected on drill collar body 1.
In drilling process, the drilling rod connected by male joint 3 drives drill collar operation, and the landwaste after drill bit breaks rock passes through helical groove
2-1 is transported to drill collar body 1 section, because drill collar body 1 external diameter is slightly less than Wear resistance disk 2, so landwaste can be the most defeated by annular space
Delivering to top Wear resistance disk 2, and carried again up by helical groove 2-1, reduce landwaste and block up, buffer strip 2-3 arranges energy
Reduce the landwaste residual at drill collar body 1；Wear resistance disk 2 is relatively large in diameter simultaneously, drill collar body 1 can be replaced to contact stratum, its table
Topcoating has wearing layer, can increase the wear-resistant time；Even if last serious wear, it is also possible to directly change Wear resistance disk 2, by breakage
2 times factory's Repair gene of Wear resistance disk after can reuse, can be the most cost-effective.
The above is only preferred implementation of the present utility model, it is noted that this utility model is not limited to aforesaid way,
On the premise of without departing from this utility model principle, moreover it is possible to improve further, these improvement also should be regarded as protection of the present utility model
Scope.
