GEOPHYSICAL ASPECTS OF INTERPRETATION OF REMOTE OBSERVATIONS IN THE TASKS OF GEOLOGICAL AND GEOECOLOGICAL RESEACHS OF GEODYNAMIC PROCESSES

(Akovetsky V.G. )

The article analyzed the current trends in the development of methods for interpreting remote observations in the tasks of geological and geoecological researches of geodynamic processes. The results of a qualitative and quantitative assessment of visual interpretation technologies for structural indicators of fault tectonics in the search for oil and gas fields are presented. Model of two-stage automatic interpretation of remote observations of geological fault are considered taking into account the geophysical aspects of modulation of electromagnetic radiation by objects of the earth’s surface. The implementation of this model in the developed Lineament software module is shown. The results of practical testing of the program module in the problems of qualitative and quantitative interpretation of the observed indicators of geodynamic processes in the studied territories are presented.......

DETERMINATION OF POROPERM PROPERTIES OF SALINE TERRIGENOUS ROCKS - RESERVOIR OF ONE OF THE DEPOSITS OF EASTERN SIBERIA BY CORE DATA AND GIS

(Zoloeva G.M. Kulapova M.V. Karamysheva O.I. Navoyan L.U. Nikulina M.U. )

Changing reservoir poroperm properties of terrigenous rocks of the Vendian-lower Cambrian age of the NEPA-botuoba anteclise analyzed for a vast collection of specimens, shows the impact on the petrophysical properties of rocks, their lithological characteristics and secondary processes such as salinization of the pore space with halite. A salinization technique in wells with limited GIS complex is offered.......

LITHOLOGY OF OLIGOCENE AND EOCENE-PALEOCENE ROCKS IN EASTERN CAUCASUS REGION

(Sivalneva O.V. Postnikov A.V. Rakhmatullina A.S. Postnikova O.V. Zueva O.A. Idrisova E.K. )

The article describes the results of the lithological investigations and laboratory analysis that would be a base for characterization of the rocks in Oligocene and Eocene-Paleocene deposits. These investigations include sample, thin sections description, SEM, XRD analysis and pyrolysis. The results have demonstrated that anisotropy changes strictly confined to the structure and mineral composition variations. A clay component increasing causes prevalence of the elongate pores, and a carbonate component increasing causes prevalence of the isometric mesh-shape pores as well as the rock susceptibility to fracturing.......

UPSCALING IN LITHOFACIAL MODELING OF RESERVOIR ROCKS OF YARAKTINSKY HORIZON

(Izyurova E.S. Izyurov A.D. )

A detailed lithological analysis of the deposits of the yaraktinsky horizon was carried out. Cyclostratigraphic analysis and typification of well sections were performed based on lithological and geophysical data. Depending on the quantitative ratios and the nature of the distribution in the section of cyclites of silt-clay and sand rocks 10 classes (GIS-facies) are allocated. These classes characterize different facies zones and are clearly reflected in GIS curves. For seismofacial modeling, a technique was developed for the allocation of enlarged section types, which represent a set of GIS facies of all cyclites for the yaraktinsky horizon as a whole.......
