摘要： A sealed wellbore junction is conveniently and efficiently created in a subterranean well. In one described embodiment, a first assembly including a deflection device is positioned in the well adjacent a junction of parent and lateral wellbores. A second assembly is then sealingly engaged with the first assembly, thereby sealing the junction, and providing fluid communication between the lateral wellbore and upper and lower portions of the parent wellbore. Sealing engagement between the first and second assemblies may be provided by a variety of sealing members, or by metal-to-metal contact between the assemblies.

摘要： A method of completing an uncemented wellbore junction provides a well completion in which a tubular assembly is installed through a wellbore junction and then is left uncemented in the junction. Fluid communication is permitted between the interior of the assembly and a formation surrounding the junction after the completion. The method is especially useful in situations in which the formation surrounding the junction is relatively impermeable or is in a production zone, and the method additionally permits convenient access to a lower portion of a main wellbore for stimulation or abandonment purposes after the completion.
