In water well drilling rig operations, optimizing mud circulation boosts bit efficiency greatly.
-
For pure clay,
use low-solids mud (
under 3%
solids)
to reduce bit adhesion.
-
Match pump capacity to bit’s debris removal—keep at 20-30m³/h for timely cuttings transport.
-
Install desilters and shakers to remove particles over 0.074mm, maintaining flow.
Add small PAM in clay-sand layers to enhance sand carrying. Monitor viscosity; water well drilling rigs perform better with fine circulation control.
