The Surface Drive plays a crucial role in suspending and rotating the rod string, transmitting power to the downhole Progressive Cavity (PC) Pump. This integrated system is increasingly adopted in oilfield applications due to its efficiency, reliability, and safety features.
✅ High-Performance Power Transmission – Ensures efficient energy transfer to the downhole PC pump for optimal fluid lifting.
✅ Enhanced Safety Mechanism – Equipped with high-performance double-cylinder brake clamps to:
- Ensure safe operation of the drive head.
- Effectively prevent reverse rotation in case of a machine halt.
- Eliminate potential operational hazards in the pumping system.
✅ Durability & Stability – Designed to withstand heavy loads and operate in harsh oilfield environments.
✅ Seamless Integration – Works in tandem with PCP systems, providing stable and continuous pumping operations.
🔹 Heavy Oil Production – Efficiently handles high-viscosity crude.
🔹 High-Sand Content Wells – Reduces wear and extends equipment lifespan.
🔹 Deep Wells & Gas-Lifted Wells – Provides reliable power transmission for various well
