Solids Control Equipment play important
role in the mud cleaning and recycling. One oil drilling well can consume
million dollars of drilling chemicals. Good design heavy duty SCE can help to
remove the impurities and clean the mud in high efficiency way, thus to improve
the reuse rate of valuable drilling fluids and reduce the cost in drilling
fluids.
Traditional mentioned 4 stage solids control equipment concluding shale shaker, desander cyclones, desilter cyclones, decanter centrifuge. Each stage will remove some cuttings in a certain particle size and the drilling mud will be cleaned step by step.
The shaker will remove the biggest particles from the drilling fluids by shaker screen. And the shaker screen API size is usually adopt API 60 to API 120. According to the drilling process, the mud engineer will advise the suitable screen size for shale shaker.
The desander cyclones and desilter cyclones are usually mounted on the shaker deck to form a mud cleaner or mud conditioner, it is 3 in 1 unit with compact footprint. The cyclones need to be feed by centrifugal pumps 45kw or 55kw, and the high pressure of feeding can form the Swirling flow in the cyclones which the bigger solids particles will be separated from the drilling fluids.
The centrifuge usually has middle speed and
high speed, the middle speed centrifuge will play the role to recover barite
for reuse. (Barite is the material to get weighted mud), and the high-speed centrifuge
work to cut mud weight to adjust the mud weight to fit for the drilling
requirement.
Our solids control equipment working in Nigeria including 6sets 18in Big bowl centrifuges, 3sets Vertical cuttings dryers, lot of screw conveyors, lot of pumps etc. As the frequency failure of shaker screens, the heavy burden of mud cleaning has shifted to decanter centrifuge, and this is the main reason why the client shifted the centrifuge size from 14in centrifuge to 18in big bowl centrifuge. Some key technical features of our centrifuges and vertical cuttings dryers as follows:
Treating capacity varies on different mud with different density or viscosity
OOC less than 5% for OBM cuttings discharged from shaker
Interlocked main motor and oil pump motor for safe operation.
Air Knife System for cleaning screen to avoid block for option
Individual Oil Lubrication System with automatic alarm & automatic shutdown for pressure limit.
The screen basket is processed in high precision to ensure easy replacement
Decanter Centrifuge with premium industrial design, reasonable and reliable
Centrifuge bowl made from SS2205 / SS2304, processed by centrifugal casting
Centrifuge impeller made from SS304 / SS316, welding to the shaft by full penetration
Centrifuge impeller protected by tungsten carbide alloy tiles or hard facing special technology
ONLY adopt SKF or FAG original bearing, to ensure the stable performance and lifetime of bearing
Adopt Siemens PLC + HMI touch screen to program and display, convenient operation
Except for Vertical cuttings dryer and mud decanter centrifuge, we offer provide high quality centrifuge feed pumps by Netzsch brand nemo pump (which is a replacement to Mono pump); as well as high quality screw conveyors required to work together to convey the drilling cuttings from shaker to Vertical cuttings dryer. We can offer both good quality equipment and reliable after sales service. Welcome to contact us freely if you have any requirement in solids control equipment.
