Abstract
The impact of imposed oscillations on the flow of liquid in porous medium is examined in this paper. Two models of porous medium were used. The first model is presented as a capillary, radius of which varies sinusoidally. The second model is two-dimensional area of flow, received from the results of X-ray microtomography of a real core sample out of carbonate reservoir. Geometrical sizes of calculated areas match real sizes of seeds of core samples. Mathematically, liquid flow process in such channels are described by equations of continuity and Navier-Stocks. Numerical calculations of flow in developed models of steam space were conducted in software FlowVision. Computer modeling was conducted both for steady flow and for flow with imposed oscillations. As a result of series of numerical calculations fields of velocities and forces were found. Received data allowed defining the laws of flow and the impact of imposed oscillations on these laws.
