RUNNING AND PULLING TOOL FOR USE WITH ROTATING CONTROL DEVICE

摘要

In accordance with presently disclosed embodiments, systems and methods for setting or removing an internal component of a rotating control device (RCD) via a pulling tool are provided. The pulling tool includes keys that extend outward for engaging with an inner surface of the internal component. The keys are spring loaded so that as the pulling tool is pressed through the internal component, the keys collapse inward until the keys are moved into a mating internal groove profile on the inner surface of the component. The pulling tool is able to selectively engage with and release from the component, both when the component is disposed in the RCD and when outside the RCD. This facilitates a mechanized installation and/or removal of the internal component from the RCD without relying on a friction force and without applying a torque or providing hydraulic fluid to the pulling tool.

主权项

1. A method, comprising:
lowering a pulling tool into a rotating control device (RCD), the pulling tool comprising an outer sleeve, a key extending from the pulling tool through a corresponding opening in the outer sleeve and to an extended position beyond the outer sleeve, and a support sleeve disposed beneath the key and coupled to an internal portion of the pulling tool; extending the key into a mating internal groove formed in a RCD internal component to selectively engage the pulling tool with the RCD internal component; and retracting the key into the retracted position to disengage the pulling tool from the RCD internal component.
