The demand for reciprocating sucker rod pumping system is also growing worldwide as the most common artificial methods for onshore wells.
However, the constant up-and-down movement of a sucker rod creates erosion wear on the rod and tubing, which if left unchecked, requires a costly intervention to make repairs.
I used a sucker rod from a well pipe to find it, then dug it out from under 7 feet of snow.
We are replacing them all with drill stem and sucker rod. My goal is to never rebuild these corrals again.
A sucker rod is a steel rod, typically between 25 and 30 feet (7 to 9 meters) in length, and threaded at both ends, used in the oil industry to join together the surface and downhole components of a reciprocating piston pump installed in an oil well.
The pump barrel is the metal cylinder in which the plunger of a sucker rod reciprocates and is an integral part of most downhole pump systems used in oil & gas wells.
The product portfolio of the company includes ESPs, gas lifts, horizontal surface pumps, sucker rod pumping, progressing cavity pumps, surface electrical equipment and services, artificial lift applications (subsea lift systems, industrial pump systems, and dewatering pump systems), and real-time monitoring and optimization.
Last September, Materion introduced its patent-pending ToughMet 3 Sucker Rod Couplings which significantly extend coupling and production tubing life.
"The lifts used include continuous and intermittent gas lifts and sucker rod pumps.
Among the trainers for the workshop are General Electric Company for Electrical Submersible Pumps, Weatherford for Sucker Rod Technologies and Baker Hughes for the Artificial Lift Selection.
During the process of sucking viscoelastic fluid, clearance between pump barrel and plunger, and rod tube flow passage lead to the increase of down resistance of the sucker rod, the resistance reduces gradually from the largest value at the bottom to the neutral point, which causes lateral force of the rod string, and results in partial wear.
