Application features of rock core drilling rig at different depths in shale gas development

خبر 27 طرق عرض
Shale gas reservoirs vary greatly in depth. Different rigs suit different depths, with distinct features.rock core drilling rig

 

  1. Shallow shale (<1,000m): Use light rigs. They move easily, operate simply, cost less, and finish shallow coring fast.
  2. Medium-depth shale (1,000-3,000m): Medium rigs work better. Their power and drilling capacity balance quality and efficiency.
  3. Deep shale (>3,000m): Heavy rigs are needed. They have strong power and pressure resistance, handling deep complexity for quality cores.

 

Choosing rigs by depth optimizes resources, enhancing shale gas development economics.rock core drilling rig
