MISALIGNMENT MITIGATION IN A ROTATING CONTROL DEVICE
摘要
<p>The exemplary embodiments relate to misalignment correction devices and methods for mitigating misalignment of a piece of oilfield equipment in or proximate an RCD. A rounded shoulder appears on a first surface within or proximate the RCD, and a socket profile appears on a second surface within or proximate the RCD. The second surface is configured to abut the rounded shoulder. The rounded shoulder is configured to rotate within the socket profile. Further, a floating joint may be implemented into or proximate the RCD and combined with the foregoing rotation mitigation features.</p>
