TUBULAR FILLING SYSTEM

摘要

Multiple embodiments of a system for capturing displaced fluid or adding fluid to tubulars (20) being run into or out of the wellbore are described. Several embodiments are supported by a top drive (54) with telescoping features to rapidly seal over a tubular (20) to connect to a mudline. A flapper valve (18) in one embodiment is described to keep fluid from spilling when the apparatus is removed from the tubular (20). In the event of a well kick, the valve (18) can be shattered with pressure from the mudline. In another embodiment, the apparatus can be placed in sealing contact with the tubular (20) and can incorporate a valve (84) which can be manually closed in the event of a well kick. In yet another alternative, the incorporated valve (84) can be automatically actuated to open as the apparatus sits on the tubular (20) and closed as the apparatus lifts from the tubular (20).
