Synchrotron radiation measurement of multiphase fluid saturation in porous media: experimental technique and error analysis

摘要

Multiphase flow in porous media is an important research topic. In situ, nondestructive experimental methods for studying multiphase flow are important for improving our understanding and the theory. Rapid changes in fluid saturation, characteristics of immiscible displacement, are difficult to measure accurately using gamma rays due to practical restrictions on source strength. Our objective is to describe a synchrotron radiation technique for rapid, nondestructive saturation Measurements of multiple fluids in porous media, and to present a precision and accuracy analysis Of the technique.
