Graphite is an allotrope of carbon, gray black, opaque solid, chemical stability, corrosion resistance, with acid, alkali and other agents are not easy to react. Can be oxidized by oxidant, can be used as an antiwear agent, lubricant, high purity graphite used as a neutron reducer in atomic reactors.

The role of oil graphite in the field of drilling mud: 1. Has good lubrication performance, can reduce the torque and stuck drilling accidents; 2. Good temperature resistance, suitable for deep Wells; 3. The surface of the product is smooth, and it has a self-lubricating effect when rubbing with other materials; 4. It has the function of sealing and stabilizing well wall and preventing collapse; 5. Suitable for shielding temporary plugging technology to protect oil and gas layer; 6. Good compatibility, easy to use and maintain.
