Oilfield Equipment Drilling Rig Parts-Drilling Bit
Oil&Gas Drilling PDC bits introduction
The hydraulics of PDC bits are designed to keep the hole clean and the bit cool, which in turn
increases the ROP and longevity of the bit.
Kingwell offers a wide range of PDC bits in sizes up to 24". All PDC bits are fully
customizable to meet specifi c drilling requirements, depending on the formation being drilled
and the equipment being used. Refer to page 9 for PDC bit design options.
PDC BIT OPTIONS
Steel body PDC bits are a lower cost alternative, to matrix body bits. They are generally
preferred in soft formations, such as sandstone.
Matrix body PDC bits provide excellent resistance to wear. They are commonly used in harder
more abrasive formations such as limestone and dolomite.
Number of Blades:
The number of blades on a PDC bit is largely determined by the formation being drilled.
Generally higher blade and cutter counts are used for harder formations, whereas in softer
formations fewer blades can be used to increase ROP.
Gauge protections is applied to all bit blades to insure longevity and to sustain a straighter
hole which increases ROP.
Cutter Characteristics (count and size):
Cutter count and size can be adjusted for drilling in specifi c formations. Small cutters and high
cutter count are chosen for hard and abrasive rock formations, whereas large cutters and a
reduced cutter count are preferred for soft to medium formations.
PDC bits are available with fl ushing holes or open center and either fixed or adjustable nozzles.
Options are available for all varieties of PDC bits and are designed specifi c to those PDC bits to
maximize bit performance and longevity.
