Centrifugal pump in oilfield solids control

Solids control system in oilfield is the typical 4 phase mud process system，including shale shaker, desander, desilter, centrifuge. What is the pumps info? What is solids control pump detail?

As per complete close loop solids control mud system, there is feeding pump for hydrocyclone separators, the mud transfer pump for charging centrifuge, the drilling fluid mixing pump for configuration, and/or the shearing pump for shredding drilling mud, the trip pump, etc. We also can say, there is horizontal pump, vertical pump, screw pump, etc.

Different equipments request different pumps as power resource or mud supplies. Meanwhile, different solids control system configuration will have different pumps position, design, or types.

Detail pump in oilfield solids control

For solids control equipments, the separated hydrocyclone separators or mud cleaner we must match centrifugal pump as mud feeding pump. The centrifugal pump transfer drilling fluid to the cyclones inlet line for subsequent process.

Usually, these pumps are horizontal one. They’ll be mounted on mud tanks ends or under the slant plate of shaker tank. When we set pumps under shaker tank will save much space. However, then it will be inconvenient when we repair or inspect pumps.

But sometimes in solids control system there will be vertical pump or submersible slurry pump instead of horizontal pumps.

We know in solids control system, the drilling mud seems blood to our human body. While pump will be the transfer tools. They pump drilling fluid from here there between different drilling fluid tanks or compartments.

Let’s see, after mud cleaner or hydrocyclone desilter what pumps there? Yes, the 4th solids control equipment-Decanter centrifuge. For decanter centrifuge, we need pump transfer drilling fluid from desilter compartment to centrifuge input.
