The treatment technology of oil based mud in the oilfield is inseparable from the supporting use of high-efficiency drill cuttings dryer. Oil based mud is divided into two types: water-in-oil emulsified mud and oil-based mud. The oil-to-water ratio is 50～80 and 50～20 respectively. After being filtered by drill cuttings dryer, the water content can be controlled at 6%. The oil content is less than or equal to 3%, so the processing of oil based mud cannot be separated from the drill cuttings dryer.
In the past, waste drill cuttings processed by solids control equipment were dug in pits and buried in the oilfield, causing environmental pollution. At present, the petroleum industry is gradually paying attention to the pollution of waste mud, so for the difficult problem of oil based mud treatment in oilfields, advanced drilling cuttings dryer processing equipment is used.
Drill cuttings dryer could be regarded as a vertical centrifuge, and widely used to treat drilling cuttings in oil drilling field. BWLS drill cuttings dryer equipment uses centrifugal separation to separate oil based mud. The drill cuttings dryer has a rotation speed of 900RPM and a separation factor of 420G; it has an independent oil circuit cooling system, equipped with a scientific and reasonable oil tank cooling system, and is resistant to high temperature environments. Effectively separate and recover the mud, and reuse it in the mud circulation system. Common wear parts can be replaced from the top of the device, and the belt can be replaced without moving any device. Efficient solid-liquid separation can minimize the mud content in drill cuttings, thereby reducing the amount of waste processed.
