Abstract: Experiments show that, by means of CT scanning, following phenomena can be clearly seen: 1) Fluids flow inside the core; 2) The driving front and its changes; 3) Areas through which fluid flows in a core section;In addition,experiments with CT scanner demonstrate the real velocity of fluid flow in the core and therefore the porosity effective for fluid flow can be calculated(the concept of this porosity is different from that conventionally used in reservoir engineering).With a CT scanner, the water saturation changes in water flooded zone when water displace oil can be observed. In this paper,a brief introduction on the pore structure of rock core with a CT scanner is presented also.
