[0002] Solid lubricants can be used to produce physical separation between two contact surfaces in the field of oilfield drilling. Common solid lubricants are graphite-based solid lubricants, but such solid lubricant products have disadvantages such as high cost and unstable performance. Coupled with the country's protection and control of energy and the environment, it is necessary to improve the traditional solid lubricant preparation method; currently, most major oilfields use the method of burning waste mud blocks into bricks for the treatment of waste mud blocks. This method has problems of air pollution and waste of recoverable physics in the waste mud blocks; furthermore, the scheme of combining the two to utilize mud waste to produce solid lubricants sustainably has been gradually used.
