发明名称 Swellable packer in hookup nipple
摘要 A screening assembly with a swellable packer incorporated onto the exterior of the screen that swells in the presence of water or hydrocarbons. The swellable packer swells at a rate that allows the gravel pack operation to proceed without hindering the gravel pack operation but then swells to seal the annular region around the exterior of a blank tubular at the upper end of the screen. By running in a swellable packer with the screen assembly at least one additional trip into the wellbore may be eliminated.
