Main ingredients
Oil based lubricant for drilling fluid is a type of oil-based lubricant that is made from mineral oil or vegetable oil as the base material, surfactants, lubrication enhancers as auxiliary materials, and moderately esterified.
Nature and Use
The product is a uniform and flowable liquid, effectively reducing the friction between the drill pipe and the wellbore, drill pipe and casing, and drill pipe and mud during the drilling process. Especially suitable for lubrication in horizontal wells, large displacement wells, window wells, and some difficult wells.

Product features
1. Quickly reduce the friction between the drill bit, drilling tools, and the formation, resulting in a significant decrease in the torque of the rotary table.
2. Has good water cooling properties.
3. Has little impact on the viscosity and other properties of drilling fluid.
Usage
Just mix it directly into the drilling fluid. Recommended dosage:1.0%-2.0%。
