Common Equipment for Drilling waste management

Oct 14, 2016

Along with continuously enhanced environmental requirements, the requirements on cuttings treatment on drilling sites are more and more higher. The technology of mud zero discharge can not only solve the field environmental problems well, but also conduct a secondary recovery of waste generated by solids control system on sites, thus maximizing the reservation of useful mud. The centralized solidification of post-treated cuttings can reduce damages caused by the field operation to the surroundings.
 

Equipment of mud zero discharge mainly includes the following machines:

1. Hi-G Dryer

KOSUN Hi-G Dryer for DWM is used to recover the mud from drilling cuttings, so as to reduce the liquid/oil content in drilling cuttings to as low as about 10% (w/w) and recover part of the drilling mud, so that the drilling cost can be reduced and the drilling waste volume can be cut down, for the purpose of reducing environmental pollution.

Features and Advantages:
1. Hi-G vibration intensity (adjustable as per working conditions).
 2. Make drilling cuttings drier.
3. Bucket type feeder is more applicable to the field process.
4. Fast drilling cuttings conveying speed and higher handling capacity.
5. Screen frame tilt angle can be adjusted from -1° to 5°;
6. Rapid screen tensioning system ensures easy screen replacement;

2. Drilling Fluid Decanter Centrifuge KOSUN LW Series Decanter Centrifuge is used to separate suspended solids ≥2μm in diameter and treat the drilling mud and liquid. It is especially effective when used in oilfields and industrial services, especially in environmentally sensitive areas. The centrifuge is high in recovery rate, effective in solids control and remarkable in the reduction of cost spent on drilling mud replenishment and treatment. It is a very precise dynamic balancing machine, able to run stably at the speed of 0~3900RPM and generate a centrifugal force up to 3000G.
Features and Advantages:

1. Innovative design includes longer bowl, extending the retention time of drilling fluid in bowl, thus resulting in drier solids and finer cut point.
2. Anti-corrosion and wear-resistance bowl is available and the solids discharge ports are fitted with quick-replaceable hard alloy bushings (tiles).
3. Anti-corrosion and wear-resistance scroll is available and the scroll surface in contact with cuttings is welded with tungsten carbide layer.
4. German FAG or Swedish SKF brand bearings are available.
5. Electrical components comply with SIEMENS/Schneider ATEX or IEC Ex.
6. Screw pump and submersible slurry pump are available and can meet liquid feeding requirements of centrifuges of various customers.
