Drilling Cuttings Drying System

GN Solids Control focus on the solids control equipment, and the RD of innovative products for the drilling waste management. GN Solids Control has been widely known as a top Brand in the international market. GN Solids Control Sold over 50 cuttings dryers and over 150 decanter centrifuges in 2014. And this number continues to grow every year because of it’s quality and good performance.

GNCM-40A Standard Drilling Cuttings Drying System

 

Complete Package Total Weight Around: 18.5 Tons (Including all equipment)

1) Tank Skid Dimension:11500x2200x2052mm

This dimension fit for putting inside the 40FT container after removing centrifuge and cuttings dryer for
shipping by sea.

2) Land Transportation Dimension:11500x2300x3300mm

Lower the centrifuge and cuttings dryer to the low position while moving by trucks, this dimension fit for
land transportation fast move completed package without removing centrifuge and cuttings dryer from
the skid.

3) Operation Dimension:11500x4244x4567mm

This layout allows the drying solids discharge from the vertical cuttings dryer, and also allows the fluids
discharged from the centrifuge goes to active/storage mud tank by gravity without transfer pump.

 

GNCM-40B Standard Drilling Cuttings Drying System

 

Complete Package Total Weight Around:20.5 Tons (Including all equipment)

1) Tank Skid Dimension:11500x2200x1299mm

This dimension fit for putting inside the 40FT container after removing centrifuge and cuttings dryer for shipping by sea.

2) Land Transportation Dimension:11500x2300x3135mm

Lower the vertical cuttings dryer to the low position while moving by trucks, this dimension fit for land transportation fast move completed package without removing centrifuge and cuttings dryer from the skid.

3) Operation Dimension:11500x4244x4147mm

This layout allows the drying solids discharge from the vertical cuttings dryer, the fluids discharged from the centrifuge will stock in the catching tank below, and it needs the pump to transfer the fluids to other storage tanks.

A) Feed System Size, shape, volume and moisture content of drilled solids can vary greatly. Installing a proper delivery system to deal with the range and volume of material is critical. Normally delivery systems including

A variety of screw conveyors and chutes

Vacuum transfer systems

Positive pressure transfer systems

B) GN Vertical Cuttings Dryer The GN Vertical Cuttings Dryer processes drilled cuttings to between 3% to 5% wet weight oil. The Dryer has comfortably processed cuttings generated when drilling reached 150 feet per hour in 20-inch hole (46 meters per hour in 508-mm hole).
C) “Dry” Solids Discharge or Collection A screw conveyor is usually installed beneath the Vertical Dryer and collects the “dry” solids, which are sent overboard if regulations allow, or are collected for final disposal off-site.
D) Effluent Polishing The Cuttings Dryer effluent is typically collected and pumped to a high-volume decanting centrifuge for further cleaning. The decanting centrifuge separates the slurry into fine solids and “cleaned” fluid, which is often sent back to the active drilling fluid system. A portion may be used as dilution for the Dryer. The solids from the centrifuge can be collected in the same vessel or conveyor as solids from the Dryer.

Performance of GN Vertical Cuttings Dryer

The big advantage is that, GN Vertical Cuttings Dryer is the first unit in China to use in Both oil based drilling cuttings and water based drilling waste. So it meets clients requirement to use one set of system to treat both mud for the same well without changing the way to handle the different drilling waste.
