ROLLER CONE BIT FLUID CIRCULATION
Drilling fluid passes from the drillstring and out through nozzles
in the bit. As it passes across the face of the bit it carries the
drilled cutting from the cones and into the annulus. The original
design for rock bits only allowed the drilling mud to be ejected
from the middle of the bit . This was not very efficient and led to
a build up of cuttings on the face of the bit (bit balling) and
cone erosion. A more efficient method of cleaning the face of the
bit was therefore introduced. The fluid is now generally ejected
through three jet nozzles around the outside of the bit body . The
turbulence created by the jet streams is enough to clean the
cutters and allow efficient drilling to continue.
