EXPANDING WELL TUBULARS INTERCONNECTED BY PIN-BOX ASSEMBLIES OPTIMIZED FOR EXPANSION |
摘要 |
A pin-box well tubular connector assembly having pin and box connector members (6, 5) with intermeshing external and internal screw thread profiles is optimized for expansion downhole in a wellbore by: A) inserting a swellable dope in the gap between the pin and box connector members (6, 5) and optionally B) configuring the pin and box connectors ( 6, 5 ) such that in axial direction a gap of at least 0.2 mm is present between the external and internal screw thread profiles; and/or C) configuring the box connector member (5) such that it has at least one thread (10) that does not engage a thread on the pin member (6). |
