摘要:  渤海油田A19井为一口生产井,该井在管柱传输平衡射孔(TCP)作业后上提管柱的过程中发生了井喷。喷势迅速扩大,无法实现抢接顶驱实施常规井控作业,现场通过关闭剪切闸板防喷器实现了封井。封井后从地质因素和完井工艺因素分析井喷原因,充分考虑井内状况,通过对比法选择压井方式,最终优选置换法进行压井作业。细化方案后对于置换法压井过程中的具体实施过程和操作过程中做了详细说明,为后续类似情况做技术储备和指导。

Abstract:  BZ29-4-A19 well is a production well. After the tubing conveyed perforation (TCP) balance job, blowout happened in the process of raising pipe string. Spray expanded rapidly, so that it is impossible to pick up top drive and implement conventional well control operation. The operators chose to close the shear ram blowout preventer and realized well shutin, and then successfully implemented the lubrication well killing method to make the well out of danger. We introduce the basic situation of the well, the process of blowout and the process of lubrication well killing method.
