Single cone bit for slim hole drilling

The single tricone bit breaks rock by cutting to form a bottom hole pattern with a mesh cutting trajectory. In this unique cutting method, the tooth and the rock have sufficient contact time, which is more energy than the impact method, and the rock breaking efficiency is higher; at the same time, the number of teeth that the single cone bit touches the bottom of the well is large, and the teeth are evenly stressed , Conducive to the work of cutting structure and extending the life of the bearing system

Main structure features :

With particular structure of the cone, equal worn of the compacts in permanent contact area and alternative contact area of the bit is realized .

 

Wear resistance of the cutting structure is enhanced by setting PDC cutters in the permanent contact area of the cone where compacts are most severely worn.

 

Optimized hydraulics structure improved the cleaning ability of hydraulic system on cone and bottom hole, and assure higher ROP.

 

The bit has excellent gage protection and up reaming abilities by setting active cutting conical spherical gage compacts on head body.
