What Does Mud Mixing Tank Mean?
A mud mixing tank in the context of drilling fluids refers to the tank which helps in mixing and homogenizing the mud mix for use in the drilling operation.
Within the mud mixing tank, drilling fluid should achieve the appropriate characteristics for the drilling operation and attain a homogenous mix with proper dispersion of additives as they are added in comparatively small ratios.
Trenchlesspedia Explains Mud Mixing Tank
The mud mixing tank is a part of the drilling fluid system that is comprised of other components such as mud pumps, mud hoppers, mud buckets, mud control systems, fluid routing systems, centrifugal pumps, bulk storage and transfer systems and mud monitoring systems which can be remotely monitored and adjusted for specific situations.
Drilling fluid, which consists of various components such as bentonite, polymer additives, and weighting agents in water, oil or synthetic base, have high viscosity and need sufficient pumping to ensure that the mud is completely mixed. Effective mixing and agitating maintain good mud characteristics by reducing settlement.
A properly mixed drilling fluid will help keep the borehole open and allow for smooth drilling operations. Non-homogenous muds can cause problems within the borehole such as stuck bottom hole assembly (BHA), an unstable borehole and stuck pipe.
