PDC Bi-center Biare reaming drills, which are divided into single-sided reaming and double-sided reaming. Single sided reaming can be used for smaller wellbore sections and then expanded to larger wellbore sections. Brightway can design and produce multiple specifications of PDC reaming bits, including...
PDC Bi-center Bit are expansion drill bits, which are divided into single-sided expansion and double-sided expansion. Brightway can design and produce PDC Bi-center Bi with multiple specifications, such as single-sided expansion drill bits and double-sided expansion drill bits. Can be used in medium hardness formations or formations with soft interlayers.
● Optimized bit profile and cutting structure, force balance and anti-whirl design reduce vibration severity while achieving aggression, it creates smoother, effcient drilling.
● Aggressive cutting structure designed with Ф16mm premium cutters for higher ROP.
● Computational Fluid Dynamics Similuation and Hydraulics Optimization for better cutter cooling and cutting evacuation to enhance ROP and Bit life.
● TSP Premium cutters for Super Gage Protection: enhanced bit stability, bit life and hole quality.
