This week we shipped one unit of oil based drilling waste management system for CNPC, they ever bought similar system before for their domestic and international projects.
To get ideal result of the discharge cuttings and recover oil as much as possible, the performance of vertical cuttings dryer is the major concern. GN has a lot of successful experience for drilling waste management projects, our vertical cuttings dryer has been improved to E version from the year of 2013 when we firstly produce the vertical cutting dryer as per our client’s suggestion and site feedback. From the first A version to the existing E version vertical cuttings dryer, it has been more and more user friendly and maintenance cost has been reduced a lot.
We have 900rpm, 1200rpm rotary speed for option to meet different requirement, the G force is up to 420G / 750G, and the screen basket opening can be 0.25mm, 0.35mm, 0.5mm for option for different drilling waste conditions. The screen basket and screen basket frame is separated, the operator only need to replace the single screen basket when it is wear. The independent oil lubrication system is for better lubrication of the bearing to prevent it from over heating. The automatic interlock system between oil pump motor, main motor and flush pump motor is equipped in case that the main motor starts before oil pump motor.
The decanter centrifuge is used after the vertical cuttings dryer to treat the fluids discharged from the vertical cuttings dryer, after treated by the centrifuge, the fine solids over 2 microns can be separated mostly, the fluids can be used to prepare for new drilling fluids or reuse directly. The high speed decanter centrifuge is used for low gravity solids, the max speed is up to 3900rpm.
