针对部分防喷杆式泵在投产后不出液原因进行调查研究,本文认为主要原因是防喷杆式泵防喷器没有打开所致。结合理论和实践分析防喷器打不开原因,通过实践摸索,探索出防喷杆式泵防喷器打不开的解决对策。在防喷器没有打开的情况下可以通过碰泵或往油管内灌水的办法打开防喷器,使油井正常生产。
For some anti-bar pump in the liquid after the start of the cause of non-liquid research, this paper believes that the main reason is anti-bar pump failure to open due to BOP. Combined with the theory and practice, the blowout preventer can not be opened up without reason. Through practical exploration, it explores the countermeasures to prevent the blowout preventer from opening up. If the blowout preventer is not open, the blowout preventer can be opened by touching the pump or pouring oil into the oil pipe to make the oil well work normally.
