Assessment of perspectives of gas and oil fields in layers of heterogeneous structures

Assessment of perspectives of gas and oil fields in layers of heterogeneous structures - software of automation of assessment of prospects of gas and oil fields in layers of porous heterogeneous structures (coals, slates).

On December 15, 2015 the press service of NITU "MISIS" announced preparation for release of software of automation of assessment of prospects of gas and oil fields in layers of porous heterogeneous structures, half reducing the cost of search works and costs of time for them, preventing emergence of emergency situations when developing fields.

In the course of creation of software the group of scientists of NITU "MISIS" develops unique mathematical algorithms.

Our work is intended to make geological exploration really high-precision and at the same time economic tool of the extracting industry: a part of works soon, we hope, will be virtually carried out - the data obtained "in fields" will be entered in the program which at the exit will give predictive model: this subsoil perspective, is risks of fast exhaustion here, and there are no perspectives at all.

According to the scientist, in a basis of a method of high-precision assessment multiscale modeling of processes of filtering in porous hydrogene structures which bowels of the earth are is put. Modern mathematical methods of multiscale averaging is a tool which allows to build projections of behavior of difficult heterogeneous macrosystems on their micro and to nanocharacteristics at influences of the different physical nature. In other words, gas content of breed is defined not only by existence in it of cavities, a time and cracks of macro-scales, but also features of its structure on micro and nanolevels.

Multiscale averaging is based on selection of a characteristic structural fragment of the material (a frequency cell) having final dimension, assessment of some properties of cells of frequency (for example, Jung's module, etc.), the choice of the physical and mathematical models describing behavior of a cell at specific influence (for example, sorption or filtering of gas, mechanical loading, thermal influence, etc.). On the basis of averaging of properties of a cell the behavior model of a system in general is under construction. Elena Kossovich, participant of the postdoc research program of NITU "MISIS"

At this development stage methods of multiscale averaging are used for modeling of difficult processes of filtering of gas in slates, and on the basis of the carried-out calculations is shown - processes of their gas recovery in many respects depend on structure of organic inclusions which amount is only tens and hundreds of nanometers. The technique of extraction of true values of elastic moduluses of microcomponents of coals (according to their nanoindenting) based on the solution of contact problems of a system a sample substrate is developed for assessment of mechanical properties of coals by scientific group.
