Why are mud pumps (used in drilling rigs) reciprocating instead of a centrifugal pump?

As we all know that mud ( Drilling fluid) is used to prevent formation fluids from entering into the well bore, keeping the drill bit cool and clean during drilling, carrying out drill cuttings, and suspending the drill cuttings while drilling is paused and when the drilling assembly is brought in and out of the hole. The drilling fluid which is used job is selected job specifically to avoid formation damage and to limit corrosion. The viscosity of this mud changes from formation to formation, so there is quite a lot of fluctuation of viscosity.

mud pump

So if we will be using the centrifugal pump we have to use different pump for different mud ( different viscosity ), as for these pumps with change in viscosity :
1. The brake horsepower requirement will increase.
2. Reduction in the head which is produced by pump.
3. Some reduction in capacity will occur with moderate and high viscosities.
4. The pump’s efficiency will decrease.

centrifugal pump

This all happens because frictional losses within the pump increases with increase in viscosity.

Whereas if we will be using a Positive displacement ( reciprocating pump ), with increase in viscosity, flow rate also increases because the higher viscosity liquids will fill the clearances of the pump, causing higher volumetric efficiency apart from this, reciprocating pump can also operate at lower speeds and impart low amounts of shear energy to the fluid compared to a centrifugal pump ( shear energy is quite an important factor if we are handling a shear sensitive fluid ).

Top quality drilling fluid centrifugal pump of DC companys

As we know, centrifugal pump is also called sand pump which plays an important role for drilling muds transfer in solid control system. Such as, the drillings from mud tank to shale shaker, the pump is the connection as bridge.

DC produce the centrifugal pump with reliability 、 heat-resistant 、large flow 、long life 、low- energy consumption 、easy maintenance and other advantages.

sand pump

Centrifugal pumps are commonly used to handle medium between -20℃~105℃, and even higher temperature medium of provided with cooling measures in case of needed. They are suitable for chemical, petroleum, metallurgy, electric power, papermaking, foodstuff, pharmaceuticals, synthetic, etc. industry. They are featured by wide range of performance, high efficiency, superior standardization, easy maintenance, etc.

DC also offers its pumps mounted on skid packages horizontal electric, vertical electric, close coupled electric, horizontal diesel, overhead belt and side belt, and wired with starters, if so desired.

The Use of Decanter Centrifuges for Unweighted Drilling Fluids

Decanter centrifuge are used to process unweighted and weighted, water-based and oil-based drilling fluids (mud). Mechanical energy is utilized to increase the gravitational force exerted on solids that are present in the mud system. Oilfield Decanting Centrifuge are able to apply over 3,000 G-forces on the liquid/solids mixture, which separates the heavier solids from the lighter solids. Additionally, high G-forces separate fine solids from liquid.

centrifuges

When centrifuging the unweighted drilling mud, keep in mind the following:

Operate the centrifuge with High G force as the solids loads are low
Adjust the weir to a deep pool to maximized solids separation
Control a smaller mud feed rate to increase residence time
Operate centrifuges in parallel, not in series if multiple centrifuges are required.
The Use of Decanter Centrifuges with Weighted Drilling Fluids

DCLW series decanter centrifuges are specially designed for the drilling mud solids control. The effective centrifuging and fine drilled solids separation can remove significant quantities of inseparatable solids. This significantly reduces the tranditional dilution requirements and drilling waste volume for disposal.
