Design of a sucker rod pumping system
Ana Ponoćko (2024)For a long time in the history of oil production, sucker rod pumps have been the first and in many cases the only choice when it comes to mechanical extraction methods. Proper selection of each individual element of the system enables optimization, which entails benefits in the form of increased efficiency and reduced costs. The first part of the paper presents the underground and surface equipment of the rod pump and describes the operation of the entire system. The ...... During the discharge cycle, the plunger moves toward the bottom of the cylinder. The relationship between the distance traveled by the plunger and the pressure change caused by the fluid inside the pump depends on the 8 compressibility of the fluid mixture inside the cylinder. If the fluid is nearly ...
