5 1/2 Inch Single Core Tci Tricone Bit For Oil And Gas

5 1/2 inch single core bits for oil and gas

This series of bits suitable for slim hole drilling operations such as sidetracking and reentry operations

The size range of YC series bir is 3 1/2-6 1/2inch and its IADC code is 437-637

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 worm

.optimized hydraulics structure improved the cleaning anility 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.
