环空蹩压在钻井生产中时有发生,我们应该重视,了解其发生的原因以及相应的解决办法,并以预防为主。如果操作处理不当,不仅影响钻井速度,还可能会造成严重的钻井事故。本文主要是从钻井实际生产出发,从实际的经验中总结一下环空蹩压的形成原因以及预防、处理方法。 The annihilation of the annulus occurs frequently in drilling production. We should pay attention to the reasons for its occurrence and the corresponding solutions, and take preventive measures as the basis. If not handled properly, not only affect the drilling speed, but also may cause serious drilling accidents. This article is mainly from the actual production of drilling starting from the actual experience to summarize the causes of annihilation of the annulus and the prevention and treatment methods.
