VERTICALLY MOORED PLATFORM CASING TIEBACK |
摘要 |
<p>VERTICALLY MOORED PLATFORM CASING TIEBACK Special J-slot connectors have been devised for connecting concentric riser pipes and casing from a structure at the surface of a body of water to corresponding concentric casings set in the sea floor. This can be called a "tieback tool" for sealingly securing a first tubular member suspended from a vessel floating on a body of water to a casing in the wellbore in the bottom of the body of water. Special multiple axially aligned J-slot means are also provided together with means to assure proper "makeup" of the J-slots. Means are also provided for proper alignment of circumferentially spaced J-slot connectors. Special selfenergizing seals are also disclosed.</p> |
