  • KOSUN KSMR Series: High-Efficiency Mud Recycling System for HDD & Trenchless Projects

    Horizontal Directional Drilling Technology
     
    Horizontal Directional Drilling (HDD) is a core technology for trenchless underground pipeline installation/laying. A pilot hole is first drilled using a directional drilling tool, then the hole is gradually enlarged to the appropriate pipe diameter, and finally the pipeline is pulled back to complete the installation. It can cross obstacles such as roads, rivers, and buildings with minimal surface damage and is widely used in gas, communication, and drainage pipeline construction.
    Mud Performance

     
    In HDD operations, drilling mud plays a crucial role. Mud performance directly affects drilling efficiency, borehole stability, and drill string lubrication. The following are the main performance requirements for HDD drilling mud:
     
    Carrying Drill Cuttings: The mud must have good suspension capacity to ensure that drill cuttings are effectively carried out of the borehole.
    Lubricating Drill Strings: Reduces friction between the drill pipe and the borehole wall, lowering torque and drag.
    Stabilizing the Borehole Wall: Prevents borehole collapse and diameter reduction, especially in loose formations or aquifers.
    Cooling the Drill Bit: Reduces drill bit temperature and extends its service life.
    Controlling Formation Pressure: Balances formation pressure and prevents water inrush or leakage.

     
    Solids Control Methods
     
    To remove drill cuttings, sand particles, and other impurities from the circulating drilling mud, maintain mud performance stability, and achieve efficient reuse and environmentally friendly treatment of the mud, solids control of HDD mud is necessary.
    Without solids control, drill cuttings will accumulate in the mud, leading to abnormal mud viscosity and density, impairing its sand-carrying, wall-protecting, and lubrication functions, potentially causing accidents such as stuck drill bits and borehole collapse. It will also accelerate drill bit wear, increase mud consumption and waste disposal costs, and even cause environmental pollution.
    Currently, the commonly used methods for solids control of HDD mud are sedimentation, dilution, and mechanical removal.
     
    Sedimentation: A mud pit or more is dug at both the entry and exit points of the drilling. Returned mud is introduced into the pits. After a certain period of natural settling, the upper liquid phase is extracted and reintroduced into the mud circulation, while the bottom solid phase is discarded. Advantages: Simple operation, low cost, low energy consumption; Disadvantages: Large site occupation, slow settling and separation speed, and difficulty in removing the bottom solid phase.

    Dilution: The mud returned from the crossing is recycled into the mud tank, and then water, sodium bentonite (sodium carbonate is an additive, bentonite is the mud itself), and additives are added to adjust the mud properties to meet the crossing requirements, thereby reducing the solid content of the mud. Advantages: Simple method, low cost; Disadvantages: Incomplete solid phase removal.

    Mechanical Removal: This method uses a solid phase control system to separate the solid phase. The solid phase control system refers to a system composed of a mud shale shaker, desander, desilter, mud cleaner, decanter centrifuge, and circulating tank, etc., according to the requirements of solid phase control. In most cases, mechanical removal is the most effective and economical.

  • KOSUN Drilling Mud Cooling System, Essential Cooling for Deep Drilling Projects

    In oil drilling operations, the circulating mud is the core of drilling, and the mud cooling system is the key mechanism to maintain its optimal condition and performance. As oil and gas exploration moves towards deep and ultra-deep wells, bottom hole temperatures often exceed 200℃, and in some deep formations, temperatures reach as high as 260℃. Mud cooling has evolved from an auxiliary process to a core technology ensuring safe and efficient drilling. KOSUN mud cooling system utilize advanced technology to provide an effective cooling solution for the industry

     
    The primary function of mud cooling is to safeguard the integrity of drilling equipment.The large amount of heat generated when the drill bit rotates at high speed to break rocks, combined with the high temperature of the formation, can easily lead to creep of drill string materials and aging of seals. Data shows that if the mud temperature exceeds 60℃, the lifespan of vulnerable parts of the drilling pump will be shortened by more than 50%; and the failure rate of bottom hole tools will increase threefold in environments above 200℃. The performance of drilling mud is closely related to temperature. Key parameters such as viscosity and density are extremely sensitive to temperature; for every 10℃increase, its plastic viscosity decreases by 15%, significantly weakening its rock-carrying capacity. High temperatures also accelerate the decomposition of chemical treatment agents, leading to mud instability and an increased risk of wellbore collapse.
     
    Currently, among the common mud cooling technologies on the market, air cooling, water cooling, and a combination of both are the three most widely used solutions. However, the actual application of these three solutions is directly related to the water source conditions, temperature requirements, and space constraints at the drilling site, and is therefore greatly limited by objective conditions.
     
    In response, considering the specific conditions of drilling rig operations, KOSUN has tailored a more energy-efficient and highly effective automatically controllable mud cooling system for its clients.

     
    KOSUN ’s mud cooling system can achieve multi-stage cooling according to site conditions; a conventionally designed mud cooling system can achieve a temperature reduction range of 20~40°C. The system employs an intelligent automatic control system with an adaptive operating mode. When the dry operation mode cannot meet the cooling requirements, the system will activate the evaporation mode. Its closed-loop cooling method significantly reduces evaporation water volume and white smoke. The system boasts strong overall processing capacity, a small footprint, and advantages such as simple operation, easy installation, and convenient maintenance.
     
    As Deep Drilling Projects advances, mud cooling technology has become critical for overcoming constraints in ultra-deep exploration. KOSUN mud cooling systems maintain a leading position in industry development. The system plays a significant role in ensuring equipment safety and reducing operational costs. It provides a solid thermal management foundation for oil exploration efforts to reach deeper into the earth, applicable across both onshore deep wells and complex operating conditions.
