Long plunger steam injection thermal pipe primary pump
Details
The long plunger steam injection thermal pipe primary pump can realize the steam injection and transfer of the pipe column operation, which greatly reduces the operation cost.
The normal working process of the pump is basically the same as that of the ordinary tubular pump. When steam injection is required, the sucker rod column and the oil pump plunger are lowered to the position of the pump, and the steam injection passage is opened to inject steam.
When pumping, lift the rod of the sucker rod to a certain height (1.2m+ anti-shock distance) to the lower starting point of the pump. After adjusting the system, the pumping operation can be performed normally.
