发明名称 A CASING TRANSITION NIPPLE AND METHOD OF CASING A WELL TO FACILITATE WELL COMPLETION, RE-COMPLETION AND WORKOVER
摘要 A casing transition nipple and method of casing a well facilitates well completion, re-completion and workover while increasing safety and reducing expense. The casing transition nipple provides a connection between a large diameter production casing joint suspended by a wellhead and a standard production casing string. The large diameter production casing joint permits long downhole tool strings to be lubricated into the well without leaving a high lubricator profile and reduces the cost of performing many other well completion, re-completion and workover procedures.
