Drilling Waste Management

Drilling Waste Management
Drilling waste management has put forward higher requirements with the constant improvement of the environmental protection requirement. Drilling waste purification system can not only be very good to solve the environmental problems, but also can do recycling to the waste of the solid control system. While drilling cutting management system maximize retains the useful mud, and it concentrated solidify after processing of drilling cuttings. That helps to reduce the destruction of the environment in oil filed working.
Oilfield environmental drilling waste management system usually contains drying shaker, screw pump, vertical cutting dryer, screw conveyor, etc those can be used for the mud dry processing such as solids control equipment

Drilling Waste Management Process:

Key Equipment for Drilling Waste Management
1. Vertical cutting dryer
Vertical cutting dryer is mainly used in waste mud treatment for environmental protection. KINGWELL Dryer can effectively recycle
oils from the cuttings, which can effectively achieve curing transport and meet the requirements of environmental protection. KINGWELL vertical cutting dryer’s capacity is 40-50 tons per hour, and usually the oil content is lower than 3% after processing, which means KINGWELL vertical cutting dryer can conform to the requirements of the typical 6%. KINGWELL vertical cutting dryer can be used for various types of drilling mud and it is very effective to dry oil-based and compound base drilling cuttings mud.

2. Decanter centrifuge

Decanter centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and fluids. It is especially effective when used in oilfield service industry, industrial service industry and especially in environmentally sensitive areas. This type of centrifuge is high in recovery rate, effective in solid control and remarkable in the reduction of cost spent on drilling mud resupplying and management. It is a very sophisticated dynamic balancing machine, able to operate stably with the whirling speed ranging from 0 to 3900 and generate centrifugal force of 3000G.

3. Drying Shaker

Drying shaker is one of the KINGWELL’s new shale shakers combining with the international market demand which can meet the needs of environmental protection. Drying shaker is the first phase of solid control equipment. Drying shaker makes the whole tail drilling processing sustained and effective by drying, screening and purifying drilling cutting waste. And it is the perfect match with vertical cutting dryer.

4. Screw conveyor

Screw Conveyor has horizontal, diagonal and combination form. it can be used with other transportation equipment. And it works through the combined transport, separate transportation, mixing, blending, dehydration, compound, unloading and stacking, etc. the whole drilling processing. Screw conveyor is used to deal with the waste drilling fluid and cuttings transportation.
