Mud agitator is a auxiliary equipment in solid control system, which can agitate the drilling fluid to make solid phase particles suspension and keep drilling fluid uniformity. In petroleum drilling process, drilling mud is called" drilling blood" , it is the indispensable substances to keep drilling normally operate, which can keep balance the underlying pressure, carrying suspension drilling cuttings, cleaning well bottom, protecting borehole wall, colling drill bit, lubricating drill tools and transporting power.
Mud agitators whether can normally work have the big influence to the whole mud system, can keep mud uniformity and make solid phase particles suspended. Mud agitator mainly used to mix mud to prevent mud solid phase particles sediment in the tank circulating system and make the circulating mud performance is stable, and make the mud density meet the requirements of drilling.
The mechanical aspects of mud agitator mainly come from the reaction force of mud in the whole working condition, which can adjust the mud density. The quality of per mud unit volume is called mud density. The density of mud is can not be ignored part in the whole drilling process, however, the parameter of mud agitator is indirectly influence mud density, so it has real value to research mud agitator duty parameter.
