Methods to Improve Efficiency of Water Well Drilling Rig Operations in Loess Layers
To improve the efficiency of well drilling in loess layers, measures can be taken from multiple aspects.water well drilling rig
-
In terms of drill selection, choose precisely based on loess layer characteristics.
- If the loess layer is mainly loose soil, positive circulation mud washing rotary table drills can drill quickly due to their strong cuttings discharge capacity.
- If there are many pebbles or hard soil layers, composite drills like dual-purpose well drills with impact mechanisms can switch drilling modes under different conditions to enhance efficiency.
-
Optimizing mud performance is crucial for efficiency improvement.
- Suitable mud not only protects the wellbore but also carries cuttings effectively.
- Adjust mud parameters like specific gravity and viscosity according to different loess layers.
- For example, increase mud specific gravity in loose and collapsible loess to strengthen wall protection, and improve mud fluidity in hard soil to facilitate cuttings carrying and reduce repeated drilling.
-
Reasonable construction process arrangement also boosts efficiency.
- Make full preparations before construction, including site leveling and equipment debugging.
- Adopt a staged drilling strategy during operation, formulating targeted drilling parameters and techniques for different loess layers.
- Ensure smooth connection between processes, such as drill tool handling and mud supply, to reduce non-drilling time.
-
Additionally, strengthen training for operators to improve their proficiency and emergency response capabilities.water well drilling rig
