Long Plunger Primary String Pump for Steam Injection Thermal Recovery

Long Plunger Primary String Pump for Steam Injection Thermal Recovery

The primary pipe string pump can realize the primary column operation to complete the steam injection and rotation extraction, which greatly reduces the operation cost.


The normal working process of the pump is basically the same as that of the ordinary tube pump. When steam injection is required, lower the rod and plunger of the oil extraction pump to the position of the pump. At this time, the steam injection channel is opened to inject steam.


When rotating pumping, the upper rod column of pumping rod to a certain height (1.2m+ anti flushing distance) is the lower starting point of the pump. After adjusting the system, the normal pumping operation can be performed.
