TECTONIC FEATURES OF THE STRUCTURE AND EVOLUTION OF THE KHADUM DEPOSITS WITHIN THE EASTERN CISCAUCASIA BY SEISMIC DATA

(Antipov M.P. Bars F.M. Patina I.S. )

This article presents the results of complex studies on the structure of Khadum deposits based on reprocessed archival regional seismic data acquired within the territory of the Eastern Pre-Caucasus in the last decades of the previous century. The work includes seismostratigraphic analysis of Khadum complex deposits, building structural maps of its top and bottom, paleotectonic reconstruction of conditions and chronology of tectonic events in the hadumsky basin. This research allowed to understand and explore tectonic features, evolution and conditions of Khadum sedimentation.......

LITHOLOGICAL CHARACTERIZATION AND WELL SECTION STRUCTURE OF KHADUM FORMATION IN EAST CAUCASIAN REGION

(Sivalneva O.V. Osintseva N.A. Postnikov A.V. Varov Yu.Ye. Poshibaev V.V. Ganaeva M.A. )

The article describes a lithological characterization of Kadum and Batalpashinskiy deposits based on results of combined sedimentological and laboratory investigations: study of the samples and thin sections, SEM study, X-Ray analysis, Rock-Eval and X-Ray micro tomography. In addition, there is also well section characterization and comparison for two structural zones - East Stavropol Depression and Prikuma zone of uplifts. It was found that reservoir rocks in upper part of sections are thin laminated shales of porous-fractured type and in lower part - carbonate-clay rocks of fractured type. The sections in two zones are similar in contents and structure but different in thickness. The thickness is various from 40 up to 80 m towards East Stavropol Depression.......

SEDIMENTARY MODELING OF THE OLIGOCENE DEPOSITS OF THE CENTRAL AND EAST PRE-CAUCASUS

(Antipov M.P. Bars F.M. Patina I.S. Osintseva N.A. Lyapunov U.V. Karamysheva O.I. )

As a result of seismostratigraphic interpretation of the reprocessed archival data of the regional seismic profiles network managed to get a complete picture of the geological conditions of sedimentary environments of Oligocene sediments in the Central and East Caucasus. Under it 4 main zones has been allocated: the inner and outer shelf, deepwater basins with pelagic sedimentation type and the area of clay cones. Each of the selected lithofacies zones characterized by certain geological and geophysical characteristics, which are described in the article.......

INFLUENCE OF ROCKS PORE STRUCTURE ON DEPOSITS DEVELOPMENT OF KHADUM FORMATION IN EAST CAUCASIAN REGION

(Sivalneva O.V. Osintseva N.A. Postnikov A.V. Musikhin A.D. Rakhmatullina A.S. )

The article shows that the rocks of Khadum suite have various types of pore space which characterized by a certain morphometric parameters. The structure of the pore space in rocks of Morozkina balka and Pshehskiy horizons are different. Watering wells during development of the field could be due to the water contained in the microporous matrix of the rocks. There are three stages in the development of deposits, which are characterized by different levels of oil and water production and change in reservoir pressure. These features are associated with different types of pore space in the reservoir rocks, which are beginning to work on the various stages of deposits development.......
