Mud Preparation Tips for Water Well Drilling in Silty Sand Layers

  1. Key Principles for Mud Formulation
    In silty sand layers with high permeability and collapse risks, formulate high-viscosity, high-specific gravity mud to strengthen wellbore protection. Increase bentonite content to enhance viscosity, forming a thick, dense mud cake on the wellbore to prevent silty sand particle loss and quicksand.water well drilling rig
  2. Additives for Performance Enhancement
    Add appropriate thickeners and fluid loss agents to improve mud suspension and water retention. This ensures effective suspension and discharge of silty sand cuttings. على سبيل المثال, in a project, increasing bentonite by 15% and adding fluid loss agents reduced water loss to below 8ml/30min, solving wellbore collapse.water well drilling rig
  3. Dynamic Adjustment of Mud Parameters
    Adjust mud performance parameters based on silty sand compactness and drilling depth. This dynamic adjustment is crucial for smooth drilling in silty sand layers.
