  • Analysis of Solid Phase Control of Drilling Fluid and Advantages of Kosun Solid Control System

     
    Solid particles in drilling fluids can be classified into two major categories: harmful solids and useful solids, among which cuttings are the most significant harmful solids. Throughout the entire drilling process, cuttings can significantly affect the physical properties of the drilling fluid, leading to an increase in its density, viscosity, dynamic shear force, water loss, mud cake thickness, abrasiveness, viscosity and flow resistance. In addition, cuttings can also cause damage to oil and gas layers, reduce the mechanical drilling rate, increase the torque of the turntable, and lead to complex downhole situations such as obstructions during drilling and lowering, stuck sticking, well leakage, and even blowouts. Meanwhile, the presence of a large amount of rock debris will also accelerate the wear and tear of the equipment in the circulation system.

     

    The role of the solids control system
    The main function of the solid control system is to efficiently remove harmful solids from the drilling fluid while retaining useful solids as much as possible to ensure that the performance of the drilling fluid meets the requirements of the drilling process. Among various solid control methods, mechanical removal is currently the most economical and efficient treatment approach.
     
    Main solid control equipment
    The commonly used solid control equipment mainly includes vibrating screens, desanders, desilters, centrifuges and degasifiers. These devices respectively target solid particles of different particle size ranges to achieve classification treatment, thereby enhancing the overall solid control efficiency.
    System integration and optimization
    The solid control system is not merely a simple superposition of individual devices, but rather an integrated whole formed by scientifically combining various solid control devices in accordance with the requirements of the drilling fluid purification process. Reasonable configuration and coordinated operation can significantly enhance the removal effect of harmful solid phases and ensure the safe and efficient progress of drilling operations.



     

    The advantages of Kosun Solid Control System:
    1. High-efficiency classification treatment: A multi-stage combination of vibrating screens, desanders, desilters and centrifuges is adopted to achieve precise removal of solid particles of different sizes step by step, significantly enhancing the efficiency of solid control.

    3. Durable and reliable design: The equipment is made of wear-resistant materials and has a sturdy structure, which can adapt to harsh drilling environments and ensure long-term continuous and stable operation.
    4. Energy conservation and environmental protection features: The optimized system design reduces energy consumption and effectively controls drilling waste, meeting environmental protection requirements.
    5. Strong adaptability: The system configuration and operating parameters can be flexibly adjusted according to different drilling conditions and drilling fluid performance requirements.

     

  • High-efficiency solid-liquid separation technology and application

    In industrial production and environmental governance, solid-liquid separation equipment is an important piece of equipment for enhancing efficiency, reducing costs and achieving green development. Solid-liquid separation technology is widely applied in fields such as oil drilling, municipal sewage treatment, mining, chemical engineering, and food processing, and is gradually becoming a "must-have equipment" on enterprise production lines.

     


    The core working principle of solid-liquid separation equipment is based on the mechanical characteristics of multiphase fluids. Through physical actions such as gravitational sedimentation, centrifugal force field, membrane separation, and medium screening, it achieves precise separation of solid-liquid two-phase systems. The essence of its technology lies in taking advantage of the differences in physical properties such as density, particle size and interfacial tension between solid particles and liquid media, and enhancing the separation efficiency through an external force field. Common types of equipment include centrifuges, vibrating screens, filter presses and cyclones, etc. Among them, the centrifuge utilizes the centrifugal acceleration generated by the high-speed rotation of the drum (which can reach hundreds to thousands of times the gravitational acceleration) to achieve rapid sedimentation separation by taking advantage of the density difference between the solid and liquid phases, and is particularly suitable for the efficient treatment of fine particle suspensions. The vibrating screen uses the periodic mechanical vibration generated by the excitation device to cause the material to form a throwing motion on the screen surface. The liquid and fine particles smaller than the screen holes pass through the screen, while the coarse particles larger than the screen holes are retained, achieving classification and separation. The filter press is based on the principle of deep filtration driven by pressure. It uses filter cloth as the filtering medium. Under the high-pressure squeezing action of the plate and frame or diaphragm, the liquid passes through the pores of the filter cloth to form filtrate, and the solid particles are retained to form a filter cake. It is particularly suitable for the deep dewatering of high-concentration suspensions. The cyclone utilizes the strong swirling field generated when the fluid enters tangentially. Under the combined action of centrifugal force and gravity, solid particles with higher density move towards the wall of the device and are discharged with the underflow, while liquids with lower density rise along the central axis and are discharged from the overflow port, achieving continuous solid-liquid separation operation. These devices, through the optimized matching and combined use of working condition parameters, can significantly enhance separation efficiency and ensure the stable operation of industrial production processes.


     

    The application fields of solid-liquid separation equipment are very extensive. In oil drilling, it can separate drill cuttings in the drilling fluid circulation system and maintain the performance of the drilling fluid. When treating municipal sewage, it can be used for sludge dewatering and water quality purification to ensure compliance with discharge standards. In the field of mining and metallurgy, it helps with pulp concentration and tailings treatment to achieve resource recovery. In the chemical and pharmaceutical industries, it can separate by-products and improve the purity of finished products. In the production of food and beverages, it can be used in processes such as juice clarification, starch extraction, and brewing filtration. From environmental governance to resource utilization, solid-liquid separation equipment almost covers all industrial scenarios related to liquids.
     
    When purchasing solid-liquid separation equipment, enterprises should focus on multiple key factors, such as processing capacity, and match the equipment model according to the production scale. Particle size: Different equipment is suitable for different ranges of solid particles. Degree of automation, whether continuous operation and remote monitoring are required; Wear-resistant and corrosion-resistant materials to adapt to acidic, alkaline or high-wear working conditions; There is also after-sales service. Does the manufacturer provide installation, commissioning, training and long-term maintenance? Choosing a suitable solid-liquid separation equipment manufacturer can help enterprises save on later operating costs and improve overall benefits. And such equipment itself also has many advantages. It not only separates efficiently, but also has strong processing capacity and stable efficiency. It can also save energy and protect the environment, reduce the discharge of wastewater and solid waste, and meet the requirements of green development. At the same time, it is easy to operate, highly automated, and can reduce reliance on manual labor.

  • The multi-field application of drilling fluid desanders

     
    As a key unit of the mud purification system, the drilling fluid desander plays a cornerstone role in multiple industrial scenarios with its highly efficient solid particle separation technology.
    It utilizes the principle of centrifugal force field to precisely remove sandy particles from drilling fluid that damage system performance, ensuring the reliable operation of core equipment and promoting the industrial model of resource recycling. The following are several application scenarios of drilling fluid desanders:
     
    I. Oil Drilling: A dual test of performance and weather resistance
    1. Onshore deep Wells: As the well depth increases, the composition of cuttings carried by the drilling fluid becomes increasingly complex and variable.
    The desander needs to continuously deal with the challenges of mixed solid phases such as sandstone and mudstone. Its unique conical separation structure can generate a stable high-speed centrifugal field, effectively sort particles according to density gradients, significantly reduce the abrasive damage of sand particles to core components such as drilling pumps, and extend the service life of equipment.
    2. Offshore platforms: The harsh salt spray and high-humidity environment impose higher requirements on the corrosion resistance of equipment.
    The core components of the desander are usually made of corrosion-resistant alloy materials such as duplex stainless steel to ensure long-term high-precision separation capabilities under harsh Marine conditions.

     

     

    II. Geological Exploration: Adaptive Evolution under Extreme Working Conditions
    1. Complex strata: In the face of sudden changes in the strata encountered during drilling (such as sudden gushing gravel or high-viscosity soil layers),
    which cause a sharp increase in the solid concentration of the drilling fluid, the intelligent feed control system of the desander equipment can respond quickly and dynamically adjust the processing rate to ensure stable separation efficiency.
    2. Extreme environments: When operating in permafrost areas or high-altitude cold regions, the equipment is equipped with an insulation system,
    effectively preventing a sharp increase in the viscosity of drilling fluid at low temperatures and ensuring that the sand separation process is not disturbed by drastic temperature fluctuations. This highly adaptable design enables it to work reliably in harsh environments such as plateaus and deserts, providing pure mud media for geological information acquisition.
    III. Mining: The Synergy of Resource Sorting and Recycling
    1. Metal mine drilling: Drilling fluids are often mixed with valuable mineral micro-powders.
    The desander needs to be precisely controlled to distinguish the target mineral particles from the useless waste sand and avoid economic losses. Its modularly designed density adjustment unit can be flexibly configured according to the characteristics of minerals, maximizing resource recovery while protecting the drilling tools.
    2. Coal mine engineering: The desander and the coal slime treatment system work in coordination. The separated fine sand is used as underground filling material, while the coal slime is recycled as fuel, forming a closed-loop chain of "drilling – separation – reuse", significantly reducing the environmental footprint of mine operations.

     

    IV. Municipal Infrastructure: The Integration of Miniaturization and Green Construction
    1. Urban exploration: In small-scale drilling scenarios such as subway exploration or pipeline detection, portable desanders have emerged. Its highly integrated skid-mounted design is suitable for narrow Spaces and can be flexibly moved with the drilling rig. The purified slurry can be directly reused to prepare new slurry, significantly reducing the on-site discharge of waste liquid.
    2. Pile foundation construction: The desander and the slurry circulation pool work in tandem to efficiently remove sand particles and impurities mixed in during the concrete pouring process, ensuring the stable performance of the wall protection slurry and guaranteeing the formation quality and integrity of the pile foundation structure.
    In such applications, the desander not only solves the solid control problem but also strongly supports the green and civilized construction of the city by achieving zero discharge of slurry.
    The diverse application demands of various industries are constantly driving the technology of drilling fluid desanders to upgrade in the directions of intelligence,
    specialization and environmental friendliness. From special models that can withstand extreme environments to customized equipment that meets ultra-fine sorting requirements,
    its development trajectory has always closely followed the pain points of the industry, becoming a precise link in modern engineering that balances production efficiency and ecological responsibility.
