Drilling mud cuttings are solid waste generated during the drilling process, primarily composed of bentonite, drilling cuttings, water, and various chemical additives. They contain various toxic and hazardous pollutants such as alkalis, salts, and oils, making them challenging to treat.


Drilling waste mud and its cuttings are subject to strict national regulation and are classified as general industrial solid waste. They should be treated in accordance with relevant requirements and regulations. This approach ensures the recovery and protection of the environment while utilizing resources responsibly.


SEPARATE's method for treating drilling mud cuttings is as follows:


Separated waste materials such as cuttings from drilling waste are subjected to a series of purification, drying, and recovery processes to be reused as concrete aggregates.


The slurry water generated from cleaning cuttings undergoes processes like chemical treatment, destabilization, coagulation, and solid-liquid separation to form mud cakes. These can be mixed with clay or shale in a certain proportion and used for brick-making.


The separated filtrate water goes through pretreatment processes such as destabilization, coagulation, flotation, oxidation, and adsorption filtration to remove major pollutants. It can be used for oilfield reinjection, safe reinjection into geological formations, or meeting discharge standards. Wastewater, after being treated by the sewage treatment system, can achieve standard discharge.
