Clean production for oil and gas drilling

In the process of oil and gas exploration and development, the total amount of drilling fluid waste is large. At the same time, since the drilling fluid waste contains various processing agents, the composition of the pollutants is complex, the concentration is high, the chromaticity is large, and the chemical oxygen demand (COD) is high. To meet the new environmental protection requirements, there is an urgent need to accelerate the development and application of high-efficiency treatment agents and new technologies, new processes and new equipment for drilling fluid waste treatment, change the traditional end treatment ideas for drilling fluid waste, and establish a whole process control and clean production of well field closed-loop, fulfill the engineering applications, and achieve a n
