Nuclear geophysics methods-an information kernel of logging data complex interpretation system

Considered is the system for the interpretation of nuclear logging data which integrates multilevel, quantitative and qualitative, sedimentological, lithological, petrophysical, geochemical, and georhytmological information. Such system features as information exchange between specific interpretation modules, adaptation technology of adjustable petrophysical models, study and accounting of the cyclicity of geological section structure provide enhanced accuracy and efficiency of complex interpretation results. Emergent systems of such a type allow one to obtain information about the componential composition of rocks (contents of particular minerals, water and oil phases, solid organic matter, etc.), lithofacies and filtration characteristics of reservoirs, and regularities in their behavior with depth and extension in most complicated geological conditions
