The main components of drilling fluid lubricant are mineral oil and surfactants. It is a drilling fluid additive that is compounded through a special production process. It features low fluorescence and excellent anti-wear and friction-reducing properties, with no adverse effect on the rheology and filtration properties of the drilling fluid. The reduction rate of the lubrication coefficient can reach more than 80%.
Drilling fluid lubricant has significant advantages in wellbore stability, lubrication and anti-adhesion, inhibition of shale hydration and swelling, formation slurry control, and rapid drilling. It has become an essential tool for drilling high-temperature deep wells, offshore drilling, high-angle directional wells, horizontal wells, and protecting complex well sections and reservoirs. Currently, oil-based drilling fluids play a dominant role in overseas drilling and unconventional oil and gas drilling.
