The dosage of lubricate in geology survey core drilling and petroleum drilling is increasing day by day. The current lubricates are still using toxic mineral oil, such as diesel oil, as their row materials. So the application of current lubrication certainly will be limited by the strict environment requirements. A new type of high efficient lubricant (Glub) whose characteristics confirm to the environment protection requirement was introduced. The results of indoor test and field application showed that the Glub has great lubricating capacity, can well distributed in drilling fluid, forms strong and thick oil film. It can notable reduce the friction coefficient and torque and meet the requirements of drilling.
