Evolution-dynamic principles during the reconstruction of density models of sedimentation basins

© A.I. Kobrunov

The evolution-dynamic principles underlying the technologies of integrated interpretation of geologic-geophysical data are being considered. These are primarily the principle of the balanced models and secondly the principle of simulation the dynamics of the basin development. In general meaning they unite into one evolution-dynamic approach to the analysis of geologic-geophysical data representing two of its different computation - setting branches.
Realization of the balanced models principle consists in checking the integral consistency of a model as to its internal consistency as well as coordination of its geometric, topologic, physical and mechanical characteristics of physical properties and physical fields with subsequent minimal updating until receiving consistent results. While simulating density distribution it corresponds to plotting optimal gravity inverse problem solution with regard to a priori introduced optimality criteria. Some uncertainty remains during their choice.
The principle of reservoir development modeling when density distributions reconstruction consists in viscous current modeling with attraction of divergent members responsible for inflow and condensation of weights at the simultaneous evolution coordination with asymptotic approximation to a modern gravitational field. Managing operators of evolutionary process are the ones responsible for divergent and transforming members working on corresponding components of gravitational field dynamic difference. The constructed computing circuits allow to solve the problem of modeling a sedimentation reservoir density distributions development or its fragment in coordination with modern gravitational field modeling.
