Fig. 2 is the structural schematic diagram in the middle part of middle cylinder body of the embodiment of the present invention.
Specific implementation mode
In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without creative efforts, shall fall within the protection scope of the present invention.
Embodiment
As depicted in figs. 1 and 2, an embodiment of the present invention provides a kind of T-type PDC sand cleaning devices, including cylinder 1, the cylinders
For the structure that middle part is small, both ends are big, the first chamfering 2 is provided at the position that the middle part of cylinder 1 is connect with both ends；In cylinder 1
Portion is tiltedly installed with multiple strip projected parts along cylinder circumferencial direction, and the strip projected parts include upper rotation protrusion 3 and backspin protrusion 4,
The inclined direction of upper rotation protrusion 3 and backspin protrusion 4 on the contrary, between adjacent upper rotation protrusion 3, between adjacent backspin protrusion 4 with
And it is formed with runner 5 between upper rotation protrusion 3 and backspin protrusion 4；It is both provided with multiple PDC composite sheets on each strip projected parts
6。
It should be noted that the stack shell 1 and the strip projected parts of T-type PDC sand cleaning devices provided in an embodiment of the present invention are one
Body molding structure, PDC composite sheets 6 are welded on the strip projected parts.Integrated molding can improve the T-type PDC sand removals
The integral strength of device, and its is streamlined more smooth.
In specific implementation process, in order to enable the corner angle of upper rotation protrusion 3 and backspin protrusion 4 do not hinder to fluid flowing
Movement in road, preferably, in the embodiment of the present invention that one end close to each other in upper rotation protrusion 3 and backspin protrusion 4 is equal
It is set as arc-shaped.In this way, when fluid enters upper end runner from lower end runner, fluid can be along the end of upper rotation protrusion 3
Portion's circular arc flows into upper end runner, and circular arc will not only hinder fluid, but also be also possible that fluid obtains in circular arc tangential line direction
High flow velocities reach and wash away the better effect of sand setting.
In specific implementation process, preferably, in the embodiment of the present invention in upper rotation protrusion 3 and backspin protrusion 4
One end away from each other is both provided with the second chamfering 7.Second chamfering is set, enable to the T-type PDC sand cleaning devices be easier into
Go out wellbore, avoids because the top surface corner angle of upper rotation protrusion 3 and backspin protrusion 4 influence and interim card occur；Moreover, setting second is fallen
Angle can be such that it coordinates with the first chamfering, improve the overall aesthetics of cylinder.
In specific implementation process, preferably, in the embodiment of the present invention between upper rotation protrusion 3 and backspin protrusion 4
It is staggered.It is staggered in this way so that when the fluid in a lower end runner enters upper end runner, can alternately flow to different
Upper end runner, the fluid of different lower end runners collides in a upper end runner, can increase the impact force of fluid, into
One step improves the effect for washing away desilting.
In specific implementation process, if it is upper rotation protrusion 3 and backspin protrusion 4 angle of inclination it is too small, fluid from
When lower end runner enters upper end runner, the flow velocity that tangential direction obtains is not fast enough, the effect for washing away desilting can be influenced, if upper rotation
The angle of inclination of protrusion 3 and backspin protrusion 4 is excessive, then flow velocity of the fluid in runner can be affected again, causes to wash away
Desilting can not be taken away with fluid.In order to avoid there is such situation, preferably, upper rotation protrusion in the embodiment of the present invention
3 and the angle of inclination of backspin protrusion 4 be along 45 ° of the tubular axis direction.Preferably effect is washed away in this way, can ensure
Fruit, and the desilting for washing away is enabled to be taken away with fluid, it avoids blocking.
In specific implementation process, preferably, in the embodiment of the present invention, the top surfaces of the strip projected parts for institute
State the identical arc surface of cylinder body outer wall.In this way, the corner angle that the strip lifts top surface can be avoided to influence the T-type PDC
Disengaging of the sand cleaning device in wellbore improves the smoothness of the T-type PDC sand cleaning devices disengaging wellbore.
In specific implementation process, PDC composite sheets 6 be for being modified to irregular cutting bed or the lower borehole wall,
So that borehole track more flat smooth, in order to improve the efficiency of finishing, preferably, each in the embodiment of the present invention
PDC composite sheets 6 on the strip projected parts are divided equally two rows and are set up in parallel, that is, polylith PDC pieces are divided into two rows, compactly simultaneously
It is listed in together, in this way, when the T-type PDC sand cleaning devices rotate drive on boldly in the wellbore, all PDC pieces are together to irregular
Cutting bed or the lower borehole wall are modified, and dressing efficiency is improved.
The present invention is not limited to above-mentioned optional embodiment, anyone can obtain various other under the inspiration of the present invention
The product of form, however, make any variation in its shape or structure, it is every to fall into the claims in the present invention confining spectrum
Technical solution, be within the scope of the present invention.
