[Applications]
The main function of this product is to reduce the flow resistance of drilling fluids and the friction coefficient of the filter cake, reduce bit torque, improve drilling efficiency, and prevent sticking incidents. Specifically, the lubricant forms an adsorption film on the surface of metal, rock, and clay, transforming solid-to-solid friction between the drill string and the borehole wall into oil film friction, thus significantly reducing frictional resistance. Additionally, the liquid lubricant enhances drilling fluid flowability, facilitates plastification, adjusts torque, and lowers processing temperature.
[Specific Functions]
1. Reduce Flow Resistance and Friction Coefficient
The lubricant significantly reduces flow resistance and filter cake friction coefficient in drilling fluids, thereby reducing torque during drilling, preventing bit sticking, and improving hydraulic horsepower.
2. Improve Drilling Efficiency
By reducing friction and wear, the lubricant extends the service life of drill pipes and bits, enhancing operational efficiency and safety.
3. Compatible with Various Drilling Fluid Systems
The lubricant is compatible with various water-based and oil-based drilling fluids, offering good compatibility and stability.
4. Environmental Performance
Modern drilling lubricants are typically made from eco-friendly materials, minimizing environmental impact and meeting environmental regulations.
