Suction pump use conditions and classification Suction pump refers to the downhole device driven by the pumping engine to lift the crude oil in the well to the surface. Ordinary pumping pump is mainly composed of four parts: pump barrel, suction valve, piston and removal valve. Suction pump refers to the downhole device driven by […]

Pumping Well Pumping Efficiency Pumping Efficiency Influencing Factors Pumping pump working characteristics： The working principle of suction pump is consistent with that of reciprocating pump, but its structure and working parameters are special due to the constraints of working conditions. In terms of the structure of the pumping pump, in the actual oil recovery process, […]

Anti-stuck sucker rod pump Formation sand can be divided into two types: filled (loose) sand and framework sand. When the flow rate of the fluid reaches a certain value, the unconsolidated sand particles filled in the pores of the oil layer are first moved, and the oil well begins to produce sand. The outflow of […]
