- What’s the main function of drilling mud?
- As we all know, drilling mud, also called drilling fluid, is a product which is used in the process of drilling deep boreholes. The mud is an integral part of the drilling process, serving a number of functions. Then what’s the main function of drilling mud?
Yes, the most critical function of drilling mud is lubricant. Drilling generates tremendous friction, which can damage the drill or the formation being drilled. Drilling mud cuts down on the friction, lowering the heat of drilling and reducing the risk of friction-related complications. So we said it ‘s very important during the drilling
