Product Description
Natural Graphite Drilling Lubricant is a high-performance friction reduction additive engineered through a specialized manufacturing process that utilizes purified natural graphite as its primary raw material. This advanced natural graphite drilling lubricant is formulated with selective coating agents and surfactants to enhance its dispersion stability and lubricating efficiency in water-based drilling fluids. The product effectively reduces interfacial friction between multiple contact surfaces, including drill pipe and borehole wall, drill pipe and casing, as well as drill pipe and drilling fluid, while maintaining the rheological and filtration properties of the base fluid system unchanged.
The lubricating mechanism of this natural graphite drilling lubricant leverages the unique layered crystal structure of graphite, which provides exceptional slip properties and pressure resistance under extreme downhole conditions. Its platelet-shaped particles form a protective lubricating film on metal and formation surfaces, significantly reducing coefficient of friction and mechanical wear.
