MINI-MD ROLLER CONE BIT FOR SLIM HOLE DRILLING APPLICATION.

In addition to the feature of MD motor bit, Mini MD slim hole bit is also design with special bearing &seal structure and lubrication system. Mini MD bit’s cutter material and cutting structure are reasonably matches with rock properties of the formation and this eliminated the specific problems such as low drilling efficiency and cutter breakage and loss, etc. Keywords:

High reliability and long working life

New type of lubrication system

Improve bit stability, prevent bit diameter shrinkage and extend the bit’s working life

Inclined double-stable head O.D.

Optional features: D, H, K, X,Y,

D: Gage protection by diamond enhanced cutters on head O.D.:

The gage protection is significantly by adding diamond enhanced gage compacts on head OD. Bit with this feature is suitable for drilling ain directional and honrizontal well with high abrasive formation.

H: Gage protection by diamond enhanced cutters on cone:

Diamond compacts arranged in heel row or gage row for the cone can enhance gage protection and increase its working life. It is suitable for frilling in high abrasive formation, hard or extreme hard formations.

K: Cutting structure for hard plastic formation

Unique designing parameters and lengthen insert crest enlarge rock –breaking volume at the bottom hole and increase bottom hole coverage and increase ROP of the bit in hard plastic formations.

X :Convex crested wedge inserts

Inserts of this shape have high cutting efficiency and anti-rock-breaking ability and can effectively increase bit’s ROP and working life. Bit with this feature is suitable for drilling medium soft to medium hard formations.

Y: Conical-spherical inserts

If bit is equipped with conical-spherical inserts as main cutting elements then the bit is suitable for drilling in hard and brittle formation.
