Drilling waste management have two common ways to treat and recycle: on line drilling cuttings treatment and base mud recycling; off line oily waste sludge removal and treatment. On line waste management is relatively easier to handle because of the flowability, lower density, lower viscosity, the drilling cuttings can be transfer to vertical cuttings dryer directly after discharged from shale shaker. Off line waste management may require more process to get better results.

GN Solids Control is China leading manufacturer for solids control & waste management equipment. GN decanter centrifuge & GN cuttings dryer have been used in many drilling waste/ drilling sludge projects. Recently, we have one drilling waste management unit ready for delivery. The customer is famous oil service company/environmental service company in Western Africa.

Tuesday, 12 August 2014 02:07

Shield Method is one fully mechanized underground construction Method. The shield machine will be pushed forward, the surrounding rock will be supported by shield shell and segment. At the same time, excavation of soil will be conducted at the front of the excavation face by cutting device; the soil will be carried out by unearthed machiner. After that, the shield machine will be pushed forward again by jack and assembling precast concrete segment, this is the general formation process of tunnel structure.

Tunnel Boring Machine (short as TBM) and Mud system is indispensable for tunnel shield project. TBM as main equipment, mud system as auxiliary equipment to make the TBM working in a high effeciency way. Recently, one Thailand customer bought one set 500gpm mud system to match with TBM machine for Tunnel shield project. Follow to read more about this case.
