Waste drilling fluid (water-based) is the main waste produced in the process of drilling. It is a multiphase stable suspension composed of clay, weighting materials, drilling cuttings, inorganic salts and other components. With the deepening of oilfield development, the production of waste drilling fluid is increasing, and the environmental contradiction caused by waste drilling fluid is becoming more and more prominent. With the increasingly stringent requirements of environmental protection in our country, it is an inevitable trend that the disposal of waste drilling fluid without falling to the ground can meet the HSE site specification and transportation conditions.
