Recently one set of oil based drilling waste management system are ready for shipment to our client in China. The technical configuration is as below:
(1)1 set of GNCD930F vertical cuttings dryer with telescopic skid, with 900rpm speed and max G force is up to 420G
(2) 1 set of GNLW363C-VFD decanter centrifuge installed on the fluids catching tank, and screw pump as feeding pump
(3) skid assy and mud tank, the
The working process is as below:
When the drilling waste management system is installed on the rig site, the drilling cuttings will be collected by screw conveyor directly and automatically transfer to the vertical cuttings dryer for treatment. When the drilling waste management system is installed in the waste facility, probably they will use forklift with a hopper to receive the waste and dump into the collection hopper, which is connected with a screw conveyor inlet port, the drilling waste will be transferred to vertical cutting dryer feeding port automatically through its discharge port; Another way is that the client use the excavator to pick up the drilling waste and sent to the collection hopper, the collection hopper should be big enough to receive the oil based drilling cuttings.
When the drilling waste is water based drilling cuttings or mixture of oil based mud and water based mud, they can not use this system to treat the drilling cuttings. For water based mud drilling waste treatment, we normally user high G drying shaker to separate the big solids firstly, and the fluids are treat by dewatering centrifuge with chemical dosing system. For mixture drilling waste which is collected from offshore drilling rig, they can not be separately collected, we will suggest oil sludge separation unit, we have 1~2 m3/h, 5m3/h, 15 m3/h oil sludge treatment unit for option.
