Geophysical interpretation methods' improvement of Bilche-Volytska zone of Pre-carpathian foredeep complex geological cross-sections' comprehensive research results

The article considers the problem related to ambiguity of logging results, which is reflected in reduction efficiency certain interpretive methods, and as a consequence oil gas reservoirs omission. In this regard, analysis results gamma logging, spontaneous polarization nuclear magnetic were conducted. received information experimental researches cores, has allowed establishing reasons distortion radioactive electric indications considerably influence on size fields intensity. addition, gamma-spectrometric method resonance substantiated. It established that matrix rocks Neogene sediments contains minerals sulfides, oxides, include iron, copper, aluminum. That determines electronic conductivity saturated layers. Different from clarke, contents uranium, thorium potassium determined above mentioned according spectrometry. These elements affect value natural intensity hydrocarbon-saturated rocks’ field. A for determining carke content isotopes with calculation their ratio was developed unambiguously assess nature increased radioactivity rocks. justify use latest technological methods spectrometry allocation productive Well research by NMR can be effectively performed help NMLE-3 (nuclear equipment), conducted SGSM-2.
