Dispersion effects modeling while forecasting physical-geological parameters of heterogeneous media
© A.I. Kobrunov, 2014
A problem of forecasting the parameters of physical-chemical model for heterogeneous media based on available standard data selection
considered as a field of corresponding parameters dispersion is being considered. Dispersion of parameters is considered as an observed
component of medium heterogeneity effects manifestation, which is simulated by a function of concentration based on diffusion equations.
Diffusion operator is being designed based on fundamental solutions of diffusion equations, which made possible to obtain prognostic field
of dispersion for sought for parameter. A problem of reconstruction of heterogeneities density concentration in distribution of expected parameter
as a solution of integral equation of the first kind is formulated. On the basis of Mamdani rule of logical conclusion chain rules of calculation for
resultant dispersion field for prediction of heterogeneities of final parameters have been designed. An example of modeling the dispersion field
for presence of oil by one of conditional oil deposits is presented, which demonstrates validity of new notions introduced.
