Visualization CT of Characteristics Formation and Stability of Foam of Porous Media

Recently, the foam fluid is cared about by more and more academics in Enhance Oil Recovery (EOR). The CT technology has its own advantages in EOR mechanism. By researches and analyses foam flooding with BIR ACTIS (CT), this paper gives a visual description to the foam feature and distribution in media, uses a new visual method to study the oil saturation and reveals the mechanism of the foam flooding.Resultsof the study have significance for guiding the field application.
