The solid lubricant is a kind of crystalline carbon compound.It is well processed with natural mineral substance and some proportional positive ions surface active agent.The product has very good performances of lubricating,high-temperature resisting,collapsing resisting and plugging,etc.It has no fluorescence and doesn’t affect the well-logging.It is much used in all kinds of well-drilling systems.
   

   MRH solid lubricant is ranked as the important scientific projects of the year 2000 by the province scientific and technological office.In 2004,we spent 6million RMB improving the workshop,equipments and working conditions.
