Desilters and Desanders are used to process large volumes of drilling fluid to remove abrasive sands and silts that shale shakers cannot remove. KOSUN DL Series Desilter is used as the 3rd stage of solids control for drilling mud, which makes separations between 15 and 45 μm. Both Desilters and Desanders are available in a large range of configurations including stand alone, over a shaker as a mud cleaner or packaged with a supply pump as a mobile desilting unit.

Compared to onshore drilling waste processing, offshore drilling waste disposal processing cost is higher. Some oil and gas fields always set specified special landfill for oilfield waste treatment. In other areas, the operator can transport drilling waste to urban or industrial drilling waste management field to fill when it meets the discharged drilling waste standard.

Among the drilling industry, drilling fluids and mud are a considerable potential hazard to the sensitive ecosystem when contaminated. Decanter centrifuge is used to treat contaminated fluids and mud for purified and unpolluted water to be discharged into the environment. KOSUN is a sophisticated decanter centrifuge manufacturer to make this proper sustainable progress.

In recently, environmental protection is a basic state policy in China, and it has been a strategic mission and goal for our country to maintain a sustainable development of society, economy and environment.

Flights within the VERTI-G dryer create a rolling action that promotes efficient separation and prevents screen plugging. Under high G-forces created by the large cone diameter, liquid/solids separation occurs instantly as cuttings make contact with the finer-mesh, high-capacity centrifuge screen. The end result is clean return fluid and dry solids discharge.

Application

KOSUN Hi-G shaker recovers drill fluids cuttings from water-based and oil-based drilling fluids, can make the proportion of the liquid phase in the drilling to below 10%, can significantly reduce the cost of the waste discharge, and is particularly effective in the oil base mud cuttings.

KOSUN drilling fluid Hi-G shaker recovers drill fluids cuttings from water-based and oil-based drilling fluids, it can make the proportion of the liquid phase in the drilling to below 10%, can significantly reduce the cost of the waste discharge, and is particularly effective in the oil base mud cuttings.

Features & Benefits of Hi-G Dryer
1. G-force linear motion up to 8 G.
2. Hi-speeds conveyance.
3. Enable shaker to process heavier cutting loads.
4. Shaker feeder can be weir type and header box.

In the future, the development tend of drilling cuttings waste management focuses on zero discharged standard. To meet this standard, it’s not scientific and uncompleted to deal with drilling cuttings with chemical agent only. The promoting way in the future to process drilling cuttings management is to combines mechanical and chemical means.

KOSUN's screw conveyer is generally used in the drilling waste management or cuttings transportation.Screw conveyor design does not require large production areas. KOSUN screw conveyor is designed for horizontal or inclined transportation of grain and its products. Screw conveyor is comprised of a screw with tubular shaft, trough or tubular casing, inlet and outlet pipes, and drive. Maximum capacity of our KG screw conveyor is 100 t/h, up to 30 m length, and 0.5 m pitch.

As indispensable equipment in drilling waste management system, vertical centrifuge has been widely used in oilfield drilling plant for the purpose of environment protection as well as cost effective consideration. In this essay, we will mainly talk about the development background of vertical centrifuge, namely cuttings dryer and its brief working principle introduction.
