Design of Rotary Blowout Preventer Shell and Finite Element Analysis of the Key Components

旋转防喷器为钻井施工提供安全有效的压力控制,是井口安全控制的关键设备。通过对旋转防喷器壳体的设计计算及旋转防喷器关键部件的静力学分析,结果表明设计的旋转防喷器壳体满足强度要求,为旋转防喷器的设计提供可靠的依据。

Rotary blowout preventer,which provides safe and effective pressure control for the drilling construction,is key equipment for wellhead safety control. In this paper,through design and calculation of the rotary blowout preventer shell and the statics analysis on the key components of the rotary blowout preventer,it is shown that the rotatry blowout preventer shell designed in this paper meets the strength requirements,and thus it provides a reliable basis for design of the rotary blowout preventer.
