I. APPLICATION
LDG-280 drilling rig is a mechanical top-drive drilling equipment that integrates water drilling and gas drilling, which solves the difficulty of drilling air-drilling hammers in soil layers. The problem of low mud drilling construction efficiency, the dual-purpose water and gas drilling rig is suitable for various formations, and the core drilling efficiency and geological exploration are efficient and energy saving.
