In the entire process of drilling mud treatment, solid-liquid separation equipment is a key link to ensure the performance of mud reuse. KOSUN centrifuges, with their outstanding separation capabilities, can efficiently handle suspensions containing solid particles with a diameter of ≥2μm, demonstrating significant advantages in the fields of oilfield drilling and industrial services. This equipment adopts a precise dynamic balance design and can operate smoothly at a speed of 0 to 3900RPM, generating a centrifugal force of up to 3000G. It enables efficient separation of drilling fluid and cuttings, significantly reducing the cost of mud replenishment and treatment. Its application performance is particularly outstanding in environmentally sensitive areas.
The working principle of the KOSUN
centrifuge is based on high-speed centrifugal sedimentation technology. Its innovative design adopts a long rotating drum structure, effectively prolonging the residence time of the drilling fluid in the drum, thereby generating a drier solid phase and a more refined separation effect. The equipment is equipped with a corrosion-resistant and wear-resistant rotating cylinder, and a quickly replaceable hard alloy sleeve (tile) is installed at the sand discharge port of the conical cylinder. The slag discharge surface of the screw propeller is welded with a tungsten carbide wear-resistant layer to ensure the long-term durability of the equipment under harsh working conditions. The equipment adopts bearings of German FAG and Swedish SKF brands, and is equipped with electrical components that meet the explosion-proof standards of Siemens and Schneider, making it have outstanding reliability and safety.
In practical applications, the performance of the KOSUN
centrifuge directly affects the recovery and utilization rate of slurry. Data from a certain offshore drilling platform shows that the equipment has a removal efficiency of 98% for solid particles larger than 2μm, a 40% increase in mud recovery rate, and a reduction of 150,000 yuan in the cost of waste treatment per well. Its modular design can be matched with screw pumps or submersible slurry pumps to meet different liquid supply requirements, and is particularly suitable for drilling operations in complex formations such as shale gas. When dealing with high-density drilling fluid, the equipment can precisely control the separation accuracy by adjusting the rotational speed, avoiding the deterioration of mud performance caused by the loss of fine particles.
The collaborative operation of the KOSUN
centrifuge with front-end equipment such as vibrating screens and sand removers is particularly important. After the primary equipment has completed the separation of large particles, the centrifuge can focus on the removal of fine particles. This stepped-process mode increases the efficiency of the entire solid control system by more than 30%. In the drilling waste treatment process, its outstanding solid-phase dewatering capacity significantly reduces the volume of hazardous waste treatment, providing strong support for environmental protection operations.
With the development of intelligent drilling technology, the new generation of centrifuges from KOSUN has achieved automatic linkage between rotational speed and drilling parameters. When the sensor detects a change in the solid content of the mud, the system automatically adjusts the slip ratio to ensure that the separation effect is always in the optimal state. This intelligent regulation capability enables the equipment to maintain stable and efficient operation performance under complex geological conditions.
As an important component of the drilling solid control system, KOSUN
centrifuge continuously creates value for drilling operations through its technical advantages of "precise separation, wear resistance and durability, and intelligent regulation". Under the future trend of green drilling and intelligent development, this highly efficient solid-liquid separation equipment will continue to play an irreplaceable and crucial role.
