Study on well control and killing in deep well drilling

Abstract

In the process of deep well drilling, due to the relatively harsh and complex operation environment, the downhole is very complex, so it needs perfect well control technology to support. In this paper, the principle and classification of well control technology, the design of deep well control technology, deep well control technology, and the optimization of well killing methods are studied. According to the actual situation, how to use the relevant equipment and well control technology to improve the safety and reliability of deep well drilling is proposed to avoid engineering accidents to the greatest extent. It is helpful to enhance the awareness of early treatment after shut in and improve the whole process emergency management ability of drilling well control.
