It is now a national requirement for drilling waste not to be dumped on the ground so as to protect the land resources and environment.
Because the residue after the mud is processed by the solids control system during the drilling process contains a lot of harmful substances such as heavy metals, sludge, which may cause irreparable damage to the soil, special treatment is required for the drilling waste to prevent it from falling to the ground. The waste must be treated until it meets the discharge standards required by the national environmental protection regulations. This is the reason why the drilling waste is not dumped on the ground.
Drilling waste manage equipment in operation
The oilfield drilling waste management system is divided into two types according to its composition characteristics:
- Oil-based drilling waste management system
- Water-based drilling waste management system
The main mechanical equipment used in the drilling waste management system includes: drying vibrating screen, drilling cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc.
Drilling waste manage equipment at work
The use of drilling waste management system has achieved good social and economic benefits. First, the recycling of solid waste means harmless and clean production, thus meeting the requirements of recyclable economy and environmental protection. One good example is that this system has effectively helped reduce the environmental hazards in Xinjiang. Second, the smaller mud storage tank reduces the land usage and saves a certain amount of land usage fees. Third, in terms of cost, this technology has the characteristics of low cost and good economic effects. According to the company’s technical staff, the cuttings separated by this technology can reach standard discharges, serve as paving materials, crop cultivation soil, etc., and the water can be recycled to achieve the purpose of waste utilization, energy saving and emission reduction.
