Steam Injection Pump

Steam injection pump is developed according to the characteristics of the heavy oil lifting, the difference of the normal work process of this pump from the common pump is that it can be used for special well conditions, such as deviated well and horizontal well etc. When steam injection, lifting the sucker rod, the plunger will lift accordingly, when the plunger is higher than the sealed chamber about 200 mm, the steam injection hole of the sealing tube and the upper tubing string will be linked together, thus steam injection operation can be achieved.

After the completion of the steam injection operation, the sucker rod fall back, the plunger will also be back to work location. At this point, the plunger enter the pump barrel and seal the steam injection hole, after adjust the impingement distance, sucker rod pump system can return to the working state.

The operation mode of this kind of pump is the same as subsurface tubing pump.
