钻井作业的过程中极易发生井喷问题,对此采取钻井液防护以及防喷器防护。防喷器作为钻井的第二道屏障,能够防止地层流体喷出,其作用相当于水龙头,若发生溢流事故,将防喷器关上,则能够有效的防止流体喷出,前提是合理运用,因此加强对井口防喷器的应用研究,有着积极的意义,现以稠油热采两用泵井口防喷器为例,做简单的论述分析。
Blowout can easily occur during drilling operations, drilling fluid protection and BOP protection. BOP, as the second barrier of drilling, can prevent formation fluid from being ejected. Its function is equivalent to faucet. If it overflows and the blowout preventer is closed, the blowout preventer can effectively prevent the fluid from being ejected if the blowout preventer is properly used, Therefore, it is of positive significance to strengthen the research on the application of wellhead blowout preventer. A simple discussion and analysis is made on the example of a heavy oil thermal recovery dual-purpose wellhead blowout preventer.
