The Choice of the Methods Inversion Transformations at the Study of Complex Reservoirs in Eastern Siberia

For solving the problems to predict parameters and build a geological model has been developed a technique that uses new approaches of inversion of HC systems in eastern Siberia, which located in Late Paleozoic and Early Mesozoic zones, with active tectonic and dynamic development, with collectors porous and porous fractured types. The developed method includes the steps of analyzing the log and petro physical characteristics of the reservoir; selection of statistical tests to separate the properties of non-reservoir-type collector, the collector of classes - porous and fractured-porous; constructing petro physical reservoir models; sensitivity analysis of elastic parameters to saturation; selection of informative attributes; constructing forecast models. As a result, technology, which was carried out in depth cubes, the cubes were designed by type of distribution manifolds, constructed forecast maps highlighted areas with the spread of intrusive bodies with the vertical section. A particularly important result is obtaining a model of the spatial distribution of collectors in the predominant type of void space
