Analyze the core equipment of solids control system
Oct 15, 2025
In industrial fields such as oil drilling, the efficient operation of solids control systems is the key to ensuring the smooth progress of drilling operations and improving the utilization efficiency of drilling fluids. A complete solids control system cannot do without the coordinated cooperation of various core equipment. As a professional enterprise dedicated to the research and development and supply of solids control systems, Xi 'an Kosun has a deep understanding of the functions and values of different equipment in the system. With precise control over equipment performance and system integration capabilities, it creates efficient solid control solutions suitable for different drilling scenarios for customers, helping them achieve efficient separation and purification of solid particles in drilling fluids and reduce operation costs. Enhance the overall operational efficiency.
As the first line of defense for separation in the solids control system, the drilling fluid shale shaker plays a crucial role throughout the solid-phase separation process. It can quickly filter out large rock cuttings with a particle size greater than 75μm in the drilling fluid through a high-frequency shale shaker. Just this one process can remove more than 50% of the solid impurities in the drilling fluid, greatly reducing the processing pressure on subsequent equipment and laying a foundation for the efficient operation of the entire solids control system. The shale shakers provided by Xi 'an Kosun have been optimized and upgraded in terms of screen material selection and vibration frequency control, ensuring stable separation performance even in high-intensity working environments and effectively extending the service life of the equipment.
The desander following the shale shaker adopts advanced cyclone separation technology and is specifically designed for the precise separation of solid particles with a particle size ranging from 44 to 75μm in drilling fluid. Its core component, the conical cyclone, can achieve efficient separation of solid and liquid phases by means of a powerful centrifugal force field, and quickly remove sand impurities from drilling fluid.
As an important supplementary device to the desander, the desilter focuses the separation on finer solid particles with a particle size of 15-44μm. Considering the spatial layout and operational requirements of different drilling scenarios, Xi 'an Kosun adopts a modular design for the desilter, enabling it not only to operate independently but also to be integrated and installed with the desander. This significantly saves the space occupied by the equipment and simplifies the system connection process, making it particularly suitable for drilling scenarios in complex strata. In these scenarios, if fine solid particles are not removed in time, they can easily affect the rheological properties of the drilling fluid and increase drilling resistance. However, Xi 'an Kosun's desilter can efficiently solve this problem and ensure the stable performance of the drilling fluid.
The decanter centrifuge is responsible for handling more precise solid-phase separation tasks. For ultrafine particles with a diameter of less than 15μm and colloidal substances, it achieves deep solid-liquid separation through the powerful centrifugal force field generated by high-speed rotation. More importantly, the decanter centrifuge also has the function of recycling and reusing weighting materials (such as barite). While purifying the drilling fluid, it effectively reduces the waste of valuable weighting materials and lowers the material cost of drilling operations.
In addition to the above-mentioned core separation equipment, the stable operation of the solids control system also cannot do without the support of a series of auxiliary equipment. Xi 'an Kosun also provides customers with a complete set of high-quality auxiliary equipment and integrated solutions. Among them, the mud agitator can continuously maintain the uniform suspension state of the drilling fluid in the mud tank, effectively prevent solid particles from settling and blocking the pipeline system, and ensure the smooth circulation of the drilling fluid. The mud tank, as the storage and blending space for drilling fluid, is equipped with a precise liquid level monitoring and temperature control system, which enables staff to grasp the status of the drilling fluid in real time and make adjustments accordingly. The sand pump provides a stable power source for separation equipment such as desanders and desilters. The wear-resistant materials it adopts can effectively cope with harsh working conditions with high solid content and reduce equipment wear. Shear pumps are dedicated to optimizing the rheological properties of drilling fluids, especially playing a significant role in the pretreatment of polymer drilling fluid systems. Through efficient shearing, they make the performance of drilling fluids more in line with the requirements of drilling operations.
The efficient operation of the solids control system is not the achievement of a single device, but rather the result of the collaborative work of various devices through a scientific classification treatment process (shale shaker → desander → desilter → centrifuge). For this reason, Xi 'an Kosun, while providing equipment to customers, will also integrate an intelligent monitoring system to dynamically optimize processing parameters, ensuring that the entire solids control system can flexibly adapt to the performance requirements of drilling fluids under different formation conditions. From equipment research and development, production to system integration and after-sales service, Xi 'an Kosun has always taken customer needs as the core, and is committed to providing more efficient and reliable solids control system solutions for customers in the oil drilling and other fields, and promoting the high-quality development of the industry.
