Oil well pumping system polished rod protective device

Abstract

A cylindrical protective device is disclosed for the polished rod and packing of an oil well pumping system. The protective device is constructed with abrasive sandstone material, wraps around the polished rod, and is positioned on top of, or anchored to, the packing. The device has two symmetrical parts, each part having semicircular structure, the parts when joined together form a circular cavity to accommodate the polished rod therethrough. As the polished rod undergoes cyclic motion driven by a horsehead, the device smooths rough edges and oil chips, extending the polished rod's lifespan. By reducing friction and minimizing wear on the packing, the device prevents oil and natural gas leaks during the pumping process. Using the protective device, pump systems can operate more efficiently, ensuring a smoother and safer oil extraction process.
