Drilling mud weighting equipment and system

As one of the few API and ISO certified manufacturer,GN Solids Control design various drilling mud weighting equipment and system for Petroleum drilling,Micro-Tunneling,Horizontal direction Drilling,downhole drilling etc.

To know why people need to weight the drilling mud as operation goes,firstly,we need to know

Composition of drilling mud

Water-based drilling mud most commonly consists of bentonite clay (gel) with additives such as barium sulfate (barite), calcium

carbonate (chalk) or hematite. Various thickeners are used to influence the viscosity of the fluid, e.g. xanthan gum, guar gum, glycol, carboxymethylcellulose, polyanionic cellulose (PAC), or starch. In turn, deflocculants are used to reduce viscosity of clay-based muds; anionic polyelectrolytes (e.g. acrylates, polyphosphates, lignosulfonates (Lig) or tannic acid derivates such as Quebracho) are frequently used. Red mud was the name for a Quebracho-based mixture, named after the color of the red tannic acid salts; it was commonly used in 1940s to 1950s, then was made obsolete when lignosulfonates became available. Other components are added to provide various specific functional characteristics as listed above.

While operation goes,some material as composed of the drilling mud above may lose.To keep the balance of the drilling mud,drillers need to weight the drilling mud by adding chemicals into the mud.Usually,a complete drilling mud weighting system is consist of following equipment or accessories.

1)Drilling mud tank for the storage of the drilling mud

2)Mud Agitator for stiring the mud in the tank to prevent silting.

4)Mixing hoppers with venturi tube to adding mud chemicals.

5)Mixing centrifugal pump for the power for sucking fluids from tank and bring chemical into tank.

6)Mud Shear pump etc for shearing of the weighted mud.

GN Solids control design and make all above items from multi-tank system to single tank system for different applications.
