The performance parameters of drilling mud materials serve as a crucial basis for evaluating their quality. Key performance indicators include density, viscosity, shear stress, fluid loss, gel strength, and pH value. Density refers to the mass of the mud per unit volume; viscosity describes the mud's fluidity; and shear stress indicates the resistance the mud exhibits, whether in a static or flowing state.
Fluid loss refers to the volume of water filtered out of the mud over a specific period; gel strength denotes the shear stress of the mud after it has remained static; and the pH value indicates the mud's acidity or alkalinity. As these performance parameters directly impact drilling efficiency and safety, they require careful selection and appropriate adjustment.
