    摘要: A method of downhole fluid displacement and a plug utilized in the method according to which the plug is inserted in a pipe between two fluids for separating and displacing one of the fluids. The plug has a specific gravity of less than the fluid above it, so that, after the displacement operation, the plug floats to the top of the latter fluid for recovery.
