    Cyclone Desander Details

    The cyclone desander is an important equipment in the drilling fluid solid phase control system, which belongs to the second-level solid control equipment, and is used to stabilize and adjust the technical indicators of the drilling fluid. According to the diameter of the cyclone, the desander can be divided into a cyclone desander and a cyclone desilter. Generally, a combination of swirl diameters above 8 inches (about 203 mm) is called a desander. Commonly used cyclones have diameters of 8 inches, 10 inches and 12 inches. These cyclones are mainly used to separate solid phase particles with a particle size between 47-76 μm in drilling fluid.

    The cyclone desander is mainly used to separate the solid phase particles in the drilling fluid, ensure the stability and fluidity of the drilling fluid, improve the drilling efficiency, prevent the clogging of the drill bit, and reduce the pollution to the environment. Its technical parameters determine that it can handle a relatively large amount of drilling fluid within a certain range and achieve high separation efficiency of solid phase particles.

    Cyclone Desander Working Process
    1. The drilling fluid passes through the sand pump to generate a certain pressure and velocity, and enters the liquid inlet pipe of the cyclone desander.

    2. Drilling fluid enters spirally along the inner wall of the cyclone to form a swirling flow. According to the size and density of the particles, under the action of centrifugal force and gravity, the coarser particles sink spirally along the inner wall of the cyclone and are discharged from the bottom flow port .

    3. The finer particles spiral up along the cyclone and overflow from the overflow pipe. This part of the liquid contains smaller solid particles, and then enters the desilter of the third-stage separation equipment for further purification.

    4. The discharged particles will fall on the fine mesh vibrating screen below for further separation and processing.

    According to the customer's requirements for processing capacity, multiple sets of cyclones can be selected to combine into a desander to meet the needs of drilling fluid treatment.

    The cyclone desander is suitable for various oil drilling rigs, such as ZJ70, ZJ50 and ZJ40, and can be used in conjunction with the closed circulation system of drilling fluid. In addition to the application in oil and gas field drilling, the desander is also widely used in mud purification in other projects, such as trenchless horizontal drilling, geothermal drilling, diaphragm wall engineering, piling and shield engineering, etc.
