TIME-VARYING BEHAVOIRS OF THE RESERVOIR PARAMETERS IN WATER FLOODED OIL RESERVOIRS
摘要
Abstract
At present, the studies on the characteristics of time-varying parameters for the reservoirs are only limit ed in the qualitative analyses of the change mechanism and the description of the statistical method of changed pa rameters (and moreover it has been introduced into the numerical simulation). Focused on the above, on the basis of the deep analysis of time-varying mechanism for water-flooded oil reservoirs, and by means of the viewpoint of continous damage mechanics, the mathmetical modeling is first conducted for the changes of porosity and permea bility and finally the quantitative relations between these parameters and time-varying ones are established. Just based on the quantitative relations, the mechanical model is set up: first of all, from the views of mechanics, the root causes and mechanical foundation are presented in the time variations of those reservoir parameters, and furthermore the mathmetical deduced course is given in detail, finally the ultimate results are proven by tests. The study results show that the permeabilities increase with the washed multiples of the reservoirs and there are linear correlation between the varied multiples of the permeabilities and 2/3 power of the washed times.关键词
