Equipment Selection and Configuration of Water Well Drilling Rigs in Hydrogeological Exploration

Ειδήσεις 40 Views
A water well drilling rig type and configuration depend on exploration tasks, geology and environment. This ensures efficiency and quality.

 

  1. Choose by exploration precision: Use truck-mounted rigs for regional surveys—fast and mobile. For detailed work, core rigs (e.g., XY-4) get 95%+ core recovery. A province used 50 truck rigs for 1,000 survey holes; key areas switched to core rigs for high-precision data.
  2. Equip tools by geology: Loose strata need casings and mud pumps. Hard rocks need diamond bits and high-torque heads. Karst areas need wireline tools and plugging gear. A karst site used Φ150mm wireline tools and grout pumps, handling leaks well.
  3. Pick power and auxiliaries by environment: Plains use electric rigs (low noise, cost). Remote areas need diesel rigs (e.g., XY-3) for off-grid work. One mountain team added generators to diesel rigs for power. Auxiliaries like inclinometers and logging tools boost data completeness.

“Fit, efficient, economic” selection maximizes a water well drilling rig’s role. It ensures top performance in hydrogeological exploration for water well drilling rig.
