NEW STRUCTURAL-METRIC METHOD FOR DETECTING PERSPECTIVE OIL AND Gas STRUCTURES (ON THE EXAMPLE OF NURIN-KHAGSKY SQUARE IN KALMYKIA)

Introduction: the relevance of research on the development of the most comparatively less costly method is due to the need to increase the efficiency not only of prospecting and exploration, but also the development of oil and gas fields in Russia. A new method is proposed for identifying promising structures for oil and gas, based on theoretical ideas about the nature of central type structures (CTS), where a regular connection of CST radii with depths to geological and geophysical inhomogeneities is established, according to the law of shear stresses. Materials and research methods: the source materials of scientiic research are space imagery of various scales, data from soil, geobotanical, geomorphological (landscape-geoecological) studies to conirm the reliability of selected structures of the central type and liniment of various ranks. The main method is a little-known method of landscape-geoecological mapping, which is a logical improvement of the well-known method of group geological ilming. Research results: according to the concept of the nature of the central type structures (SCR), a regular connection has been established between the SCR radii and depths to geological and geophysical inhomogeneities and geodynamic centers. This is explained by the law of shear stresses, known in physics, which propagate at an angle of 45 degrees relative to normal (vertical). A new method for identifying promising structures for oil and gas has been developed, and a vivid example of using this method is given on one of the promising areas in Kalmykia, where the theoretical geological and tectonic model has been confirmed by geophysical and geochemical studies. Discussions and conclusion: the new structural-metric method is fundamentally new, relatively cheap and available for use, to some extent a signiicant addition and development of the well-known structural-geomorphological method, and to some extent analogous to the structural-metric method of Zhukov V. T., Lazareva, G. E., et al. (1999) [2].
