| Zusammenfassung |
| It is provided a comparison of no equilibrium effects by independent hydro dynamical and
electromagnetic induction influence on an oil layer and the medium, which it surrounds. It is
known, that by drainage and steeps the hysteresis effect on curves of the relative phase
permeability in dependence from porous medium water saturation by some cycles of
influence: drainage-steep-drainage is observed. In earlier papers the analysis of the seism
acoustic monitoring data in regimes of phone radiation, response on the first influence of
given frequency and on the second influence is developed. For the analysis of seism acoustic
response in time on fixed intervals along the borehole an algorithm of phase diagrams of the
state of many phase medium is suggested. On the base of developed algorithm a new
algorithm of analyze of space, but integral in time for equal observation periods changing
by the method of phase diagram state of many phase medium in the oil layer is
developed. The developed method allows on quality level to classify the state of the
polyphase medium, which is the oil layer, using data of many cycles influence. In that
paper we suggest the algorithm of modeling of 2-d seismic field distribution in the
heterogeneous medium with hierarchic inclusions. Using the developed earlier 3-d
method of induction electromagnetic frequency geometric monitoring we showed the
opportunity of defining of physical and structural features of hierarchic oil layer structure
and estimating of water saturating by crack inclusions. That allows managing the
process of drainage and steeping by water displacement the oil out of the layer.
Thus, the developed methods allow on the quality and quantity levels to make a
classification of the many phase medium, which is an oil layer, using data for multiple
excitation. For quantitative solution of earlier listed events of no equilibrium and
hysteretic interaction of water and oil by out working of the oil layer, it is urgently
to add and to further develop the system of seism acoustic and electromagnetic
observations.
