钻井作业处于石油勘探开发的龙头地位,但由于钻井工程的复杂性和地质条件的复杂性,因此,钻井作业中的出现的安全问题非常突出,尤其是井喷和井喷失控事故,常常会导致灾难性的后果,本文对井喷事故的原因,井喷的征兆进行了研究,认为设计合理的钻井液、及早发现溢流、防止钻井中人的失误和违章操作是防止井喷的主要途径。对井控设备如防喷器、井控管汇等和井喷后的处理技术如关井及压井方法做了简单的讨论。
Drilling operations are at the forefront of oil exploration and development. However, due to the complexity of drilling engineering and the complexity of geological conditions, safety problems in drilling operations are prominent. In particular, blowout and blowout failures often result in catastrophic The article studied the reason of the blowout accident and the blowout signs, and considered that it is the main way to prevent blowout by designing well drilling fluid, detecting overflow early, preventing human error and illegal operation in drilling. On the well-controlled equipment such as blowout preventer, well control manifold and after blowout processing techniques such as shut-in and kill method to do a simple discussion.
