Mud Wall Protection Technology in Water Well Drilling Rig Operations in Loess Layers

新闻 91 次
Mud wall protection technology plays a key role in water well drilling rig operations in loess layers.

 

  1. The characteristics of loess layers make wellbores prone to collapse.
    • Mud forms a mud cake around the wellbore, effectively preventing collapse.
    • Mud specific gravity and viscosity are vital factors affecting wall protection. Adjust specific gravity based on different geological conditions in loess layers.
    • For loose and collapsible loess, increase mud specific gravity appropriately to generate greater pressure for wellbore support.
  2. Reasonable control of mud viscosity is also necessary.
    • Suitable viscosity ensures cuttings don’t settle easily when carried by mud, allowing smooth discharge from the wellhead.
    • 同时, mud cools and lubricates the drill bit, extending its service life and improving drilling efficiency.
  3. When preparing mud, select appropriate raw materials.
    • Generally use bentonite as the main material, adding chemical treatment agents like thickeners and fluid loss reducers to improve mud performance.
    • During drilling, monitor mud performance parameters (specific gravity, viscosity, sand content, 等。) in real time. Adjust the mud formula promptly based on monitoring results.
    • When mud performance fails to meet requirements, supplement or replace it in time.water well drilling rig
