Construction of mud stations to achieve non-landing treatment of water-based and oil-based drilling waste while drilling

• The construction of a centralized mud processing station to achieve non-landing processing of drilling waste while drilling has become a new way of environmental protection in oilfields in recent years. Take a lower-level oilfield in Liaohe ...

In recent years, the state has put forward the goal of zero discharge of drilling waste. From the source reduction of drilling waste, process control to end treatment, strict requirements have been implemented in stages in order to minimize the environmental pollution of drilling waste. . The drilling mud with water as the continuous phase is the water-based drilling mud, and the solid waste generated by drilling is included in the general solid waste management; the drilling mud with diesel as the continuous phase is the oil-based mud, and the solid waste generated by the drilling is hazardous waste.

An oil field in Liaohe Oilfield is located in Chifeng City, Inner Mongolia. According to the source, composition and characteristics of pollutants, the drilling mud produced in the block is water-based drilling mud. The earliest treatment method is to add lime and other substances after the drilling mud is discharged into the mud pool. Cure in place, and then carry out ecological restoration. According to the requirements of the new environmental protection law, some special areas at home and abroad require that drilling wastes be treated without landing while drilling. As a result, the company proposed to build a centralized mud treatment station, mainly for the treatment of drilling mud in the Liaohe Oilfield, with a treatment scale of 240m3/day.

This method of centralized processing using mud processing stations, one-time input and enjoyment by multiple wells, can greatly reduce EIA risks and construction costs. In the future, the construction of centralized mud processing stations will gradually become popular in oilfield drilling projects. As one of the few domestic companies that can independently design and build drilling mud centralized processing stations, KOSUN Machinery can provide customers with integrated solutions, from mud station design drawings to mud station equipment production configuration, and then to the mud station site construction. Whole process construction.
