It is used for high angle hole and horizontal well.
In order to achieve the above object, and then the technical solution taken is as follows:
One kind 4.5 " cutting bed removes heavy weight drill pipe, including aggravates tube body, top connection and lower contact, the exacerbation tube body,
Top connection passes through changeover portion with lower contact respectively and connects；Two sections are provided between the top connection and lower contact to be connected and be
The exacerbation tube body of coaxial inner conductor, the exacerbation tube body include that the first cleaning section, the second cleaning section and righting section, the righting section are set
It sets between the first cleaning section and the second cleaning section, for the first cleaning section with the second cleaning section except length is different, other structures are identical；
Several first helicla flutes are offered on the excircle of the first cleaning section, and several the are offered on the excircle of the second cleaning section
Two helicla flutes offer third helicla flute, first helicla flute, the second helicla flute and third spiral shell on the outer circumference surface of righting section
Spin slot corresponds；The first spiral groove and the second spiral groove are of an L-shaped structure perpendicular to the section of weighting tube body axis, described
The arc-shaped groove of third helicla flute；First helicla flute and the excircle of the first cleaning section are formed by cutting rib and are provided with
Cutting tool is provided with one layer of wearing layer on the excircle of righting section.
Further, the top connection is female adapter, and lower contact is male connection.
Further, the outer diameter of the changeover portion is less than the outer diameter for aggravating tube body, top connection and lower contact.
Further, it is respectively arranged on the excircle of one end for aggravating tube body in the top connection and lower contact resistance to
Bull ring.
Further, the wear ring with a thickness of 2-3mm.
Further, the second cleaning segment length is longer than the length of the first cleaning section.
Further, the groove body of the first helicla flute on two sections of exacerbations tube body, the second helicla flute and third helicla flute
It is consistent to move towards direction.
The beneficial effects of the present invention are: present invention setting, there are two weighted section, rationally, structure is simple and practical for design, lead to
The removing to cutting bed is crossed, make a trip in drilling process difficult, bit freezing the tool even risk and drop of drillling tool twisting off can be reduced
Low drilling cost.
