    摘要: A method and system for testing a two-phase compressible composition, such as a foamed cementing composition, enables testing for mechanical properties while maintaining original pressurized gas volumes in the composition. A specimen of the composition can be prepared, transferred and tested without disrupting the dynamic status of the specimen. This allows for testing of the composition under conditions in which the composition will be placed in an oil or gas well. A related specimen test device is also disclosed. The method includes pressurizing the two-phase compressible composition in a first vessel to a pressure greater than atmospheric pressure; pressurizing a second vessel to the pressure; transferring at least a portion of the composition from the first vessel to the second vessel while maintaining at least substantially the pressure on the transferred portion of the composition; and testing the portion of the composition transferred to the second vessel, which testing is performed while maintaining at least substantially the pressure in the second vessel.
