Kinds of «Fluid – Massive Material» Interference in Process of Evolution of Geohydrodynamic Systems of Aqueous-rocky Draws

Authors: Mavrin K. A.

The article is about the peculiarities of interference of ground water with massive materials, gases, organic substances, as well as interference of new formations of hydrocarbon fluids with massive materials and waters on the different stages of evolution of aqueous-rocky draws and transformation of the types of geohydrodynamic systems.

Mineral Association of Products of Hydrothermal Changing – Key to the Understanding of Origin of Loose Zones and Phase Zonation of Hydrocarbons (оn the Example of West Siberia)

Authors: Korobov A. D., Korobova L. A., Akhlestina E. F.

 In spite of the accepted katagenal laumontite nature from sedimentary strata, its hydrothermal – metasomatic origin in lower-chalky terrigenous deposits,recovering mineral continental rift has been proved. In rocks undergoing propylization of lower temperature, laumontite is a mineral-indicator of containers and calcite-of screens.

Approaches to Creating an Updated Biostratigraphic Base for Dividing the Callovian from the Volga Region

Authors: Seltzer V. B., Saltykov V. F.

Current reestimation of the stratigraphic positions of some zonal ammonites has resulted in revision of the sequence of ammonite zones, particularly in the Lower substage, and in more detailed stage division. The work has been mainly finished for Central Russia. But it is still in the initial stage in the Volga Region. New data is presented in the paper. Possibility is discussed of compiling an updated biostratigraphic base for dividing the Callovian not only from ammonites, but from foraminifers, as well. 

The Composition and Paleontologic Characteristics of the Callovian Depositions from the North of the Don-Medveditsa Dislocations

Authors: Saltykov V. F.

New materials on the lithologic composition, character of the boundaries between the subsuites and paleontologic age determinations are presented. Those were obtained upon stydying the well copes from the North of the Don-Medveditsa Dislocations. The data analysis has allowed to divide the depositions in new place of the Volga Region in subsuites. Those are corresponding to standart ammonite zones and peculiar for foraminifer assemblages of their own. Sandy clays occur in subsuite bottom, the boundaries between subsuites are drawn from paleontologic data in clayey section.

The Upper Cretaceous Inocerams from the Borehole Sections of the Western-Siberian Depression and Some Questions of the Turonian Stage Stratigraphy

Authors: Kharitonov V. M., Marinov V. A., Ivanov A. V., Fomin V. A.

This paper deals with research results of the inocerams from the Upper Cretaceous borehole sections of the Western-Siberian depression. The Lower and Upper Turonian inocerams – Inoceramus (Mytiloides) labiatus Schloth., I. (M.) hercynicus Petr., I. cuvieri Sow., I. lamarcki Woods (non Park.) var II Renng., I. cf. schulyinae Efrem. are described and figured. Questions of the Turonian stage stratigraphy and its dismemberment in France, Germany, USA, Canada and the former USSR are discussed.

Application of Geophysical Methods for the Decision of Engineering – Geological Problems at Research Landslip Processes in October Gorge of City of Saratov

Authors: Smilevets O. D., Ivanov A. V., Hajk N. V., Kravtsova K. A., Kuzin A. G.

In article application of a complex of geophysical methods of researches and the modern equipment for the decision of practical and engineering – geological problems is considered at designing for construction of technological constructions on landslip slopes (sites)

Physico-geological Bases of Forecasting objects, Perspective on oil and Gas by Methods of Prospecting Geophysics and Practice of their Application

Authors: Ryskin M. I.

Questions on орроrtunities of forecasting of deposits of hydrocarbons with the help of gravimagnetic methods are considered on the basis of multilevel physico-geological models of oil-and-gas deposits. Examples integration geopotential methods are shown at forecasting oil-and-gas objects and an opportunity of use of a correlation technique of division of geophysical anomalies KOMR. 

To Question for Determination Index Effective Fracturing Carbonate Collectors

Authors: Kalinin V. F.

It is shown that index effective fracturing carbonate collectors can determinant surveys of oil wells. Results of determination index effective fracturing carbonate collectors is shown in table. 

Forecast Oil and Gas Content of Bowels using Methods of Deep Geochemistry

Authors: Mukhin V. M.

This article gives a brief overview on the possible forecast of oil and gas content on the basis of the studies of DOS (dispersed organic substance) rocks and its catagenetic alteration. On an example of southern part of Buzulukskaya hollow the connection of paleozoic rocks catagenezic with the phase content of hydrocarbons deposits is traced. The original scheme of catagenetic location of the bowels for this territory has been devised on the basis of the usage of the method of calculation of total impulses of heat.

Lithological and Physical Yardsticks on Optimization Technology of Mud Acid Treatments Terrigenous Reservoirs

Authors: Kalinin V. F.

Results of laboratory and field researches on optimization of realization of mud acid treatments in the wells, opened terrigenous reservoirs at Saratovneftegaz OAO deposits, are submitted. it is shown, that efficiency of mud acid treatments of wells is determined by a degree of conformity of a mode of treatment of a layer with its geologicalphisical characteristic.
