为降低成本，减少自喷井后期修井转抽作业，塔河油田一些油气井采用自喷机抽一体化井口，但存在一定的井控风险。为保证井控安全，研制了自喷机抽一体化完井井口密封装置，提高了井口承压能力及可靠性，保证了井控安全，节约了由于压力偏高进行紧急压井、上修更换井口等的作业费用。

Flowing-pumping integrated wellhead were adopted in some wells in the Tahe oil field so as to reduce production cost and pumping operation when self-flowing wells turned to pumping during the late production period. However, there exist well control risks. A new well-hole sealing device for flowing-pumping integrated well completion was innovated to enhance the pressure resistivity and reliability of wellhead. It saved costs for emergent well killing and wellhead replacement when overpressure occurred.
