Core Differences Between Workover Equipment and Drilling Equipment
1. Drilling rigs focus on rock breaking and drilling new wells; workover rigs focus on old-well repair, process modification, and failure treatment.
2. Drilling rigs work at a fixed well location for long periods; workover rigs are truck-mounted and mobile, with rapid relocation and flexible maneuverability.
3. Drilling pumps provide ultra-high flow and ultra-high pressure for rock-breaking circulation; workover pumps are adapted to well flushing, sand washing, well killing, and chemical injection processes.
4. Drilling emphasizes the rotary drilling system; workover emphasizes the downhole tool system of fishing, milling, jarring, packing off, and stuck-pipe release.
5. Workover equipment has higher requirements for wellhead safety, pressurized operations, and well control prevention, and faces more operating conditions involving active oil and gas zones.
