Acomplete drilling rig system always includes drilling floor block, mud solids control block and recovery, mud pump and power block. Among these, the mud solids control and recovery block is consisting of drilling mud recycling and drilling mud system. This block is used to maximally recover the valuable drilling mud and reduce the waste discharge.
The drilling waste cuttings management system sometimes called the further treatment for solids control. As the cuttings was delivered from out port of the primary solids control equipment like shale shaker and mud cleaner to the cuttings dryer unit. The main equipment for drilling waste cuttings recovery include cuttings transferred equipment, Verity G cuttings dryer, feeding pump and decanter centrifuge.
The cuttings transferred equipment is regarding as a bridge connecting the primary solids control system to the waste management unit. The common and popular method to transfer the cuttings is to use the screw conveyor and hose pump.
What is the Difference of the screw conveyor and hose pump
The screw conveyor itself has a collecting groove and the screw propeller push the cuttings to the Verti G cuttings dryer. As the screw conveyor is designed to transfer the cuttings along a straight line. Usually, on the site, there are not only 1 unit screw conveyor, several unit screw conveyors are located crossing with certain angles so that the waste cuttings could be delivered to the cuttings dryer. As the cuttings dryer feeding port is high, the screw conveyor is sloping. Then if the waste cuttings are high liquid content, the liquid would be flow back and overflow out the conveyor.
The drilling waste cuttings transferring equipment is important during the operation. GN has applied both the screw conveyor and hose pump in the design of the drilling waste management system, for more information, please contact with GN freely.
