1. Product introduction
This product is based on special vegetable oil and compounded with various surfactants. It has good dispersion in water. It is a low fluorescence water-based lubricant, has no interference to geological logging, has strong emulsification and lubrication, can significantly reduce the friction coefficient, prevent bit and differential pressure sticking, and has good high temperature stability. It can resist temperature above 180 ℃ and can be used in deep wells, It is an excellent lubricant for drilling fluid of exploration well, special operation well and directional well.
