Геодинамика и металогения Восточно-Уральской мегазоны Южного Урала
Geodynamics and metallogeny of Eastern-Urals super-zone of the South Urals
http://www.ngdelo.ru/2006/1/11-26.pdf
Geological construction, geodynamics and metallogeny of Eastern-Urals super- zone of the South Urals are discussed. In early Palaeozoic era this structure formed as continental rift and it did not convert into spreading oceanic basin. In middle Devonian-early carboniferous this territory was located over the subduction zone and it developed as active continental margin. Gold and base metal minerali-zation is located volcanic-plutonic andesite complex of active continental margin.

Высоковязкие нефти: аналитический обзор закономерностей пространственных и временных изменений их свойств
High-viscosity oils: analytical review of regularities of spatial and temporal changes of their properties
http://www.ngdelo.ru/2006/1/27-34.pdf
Paper is devoted to review of general properties of high-viscous oils of Russia and foreign coun-tries, which are considered as main reserve of oil production for future years. Particularities of spatial distribution of high-viscous oils in oil-bearing territories of Russia are considered. It has shown that the most viscous oils are in Timano-Pechora and Precaspian oil-bearing basins. Analyses of regularities of oil viscosity changes depending on bedding depth shows oil viscosity decreases with depth growth. In aver-age, high-viscous oils is heavy, sulfur, high resin, high asphaltenes ones and with small content of paraf-fin's and content of IBP 200 °C .

Regularities of the pressure waves reflection from the solid surfaces covered by the porous layer
http://www.ngdelo.ru/2006/1/35-42.pdf
Some results of the research of the pressure waves reflection form the solid surfaces, cov-ered by the porous layer are presented in this paper. Some peculiarities of the dynamics of the porous media saturated with liquid or gas are regarded. A mathematical model of the wave processes in two phases media is based upon multiphase mechanics hypothesis. An analysis calculations made by of the influence of the parameters of the reflected wave was made. An effective defense can be guaranteed only by means of screens made of sponge polyester structure, the porosity being high. The model and the computer code presented in the paper can be applied to the analysis of wave impact upon zone of the layer.

Результаты применения третичных методов повышения нефтеотдачи на залежи АС5-6 Мамонтовского месторождения
Results of EOR tertiary methods application at AS5-6 deposit, Mamontovskoye field
http://www.ngdelo.ru/2006/1/73-80.pdf
Results of the EOR tertiary methods application at a pilot section of AS5-6 deposit, Mamontovskoye field, are discussed in the present paper. By using a mathematical model, which describes the technology of cross-linked polymer composition stimulation, the authors evaluate of the technical-and-economical efficiency of the technology, depending upon injection volumes and pilot section development stage. It has been discovered that if reservoirs are heterogeneous as to their permeability, there exists a development period that is characterized by a significant advance of production watering rate over the reserve recovery rate under which the physical-and-chemical effect leads to maximum technological and economic results. This period is an individual feature and it is determined by a geologicaland- physical structure of the object, and by a current development system.

The paper contains the analysis of methodological aspects, connected with the main clause of exploitation expenses for petroleum delivery in main petroleum pipelines, i.e. electrical energy consumption at petroleum enterprises. A technique for calculation of electrical energy consumption during petroleum delivery in main petroleum pipelines, being approbated at petroleum pipelines of East and West Kazakhstan (2003-2004), has been proposed. This technique showed a sufficient level of correlation between the calculation results and the real (reported) values of electrical energy consumption. One has made conclusions on measures, the implementation of which allows us to get more precise calculation results according to the proposed technique.

Prevention and washing away of tanks bottom sediments devices analysis
http://www.ngdelo.ru/2006/1/161-164.pdf
This article is devoted to the questions of prevention of sedimentation and washing away of sediments in oil tanks with the big volume. During the storage period the formation and accumulation of bottom sediments occurs in oil tank. The quantity of sediments can amount up to 25 percent of the payload volume of oil tanks per a year which makes it difficult to observe the conditions of the tank and it also leads to the rise of corrosive water lens. For the prevention of sediment accumulation on the bottom of oil tanks electromechanical mixer «Diogen» is used. However the construction of elecromechanical mixer is not perfect.

Метод оценки стоимости Гудвилл с учетом человеческого капитала и деловой репутации
Method of evaluating goodwill value which takes into consideration human capital and business reputation
http://www.ngdelo.ru/2006/1/181-190.pdf
The present article gives the analysis of non-material assets of a company including goodwill. It should be marked that goodwill includes the dominating influence of human capital and business reputation of an employee and of the whole company on its value. It can be seen from the practice that companies do not show such assets in the balance but try to demonstrate them to prospective investors and customers to increase the value of the business of their companies. It results in great gap between balance value of the assets of the company and its market capitalization. It happens due to the lack of normative base of their reflection and of methodological base for their evaluation. This article suggests the method of evaluation of goodwill which takes into consideration human capital and business reputation.

High dynamics and economic importance of fund market, the complexity of stocks' prices and portfolios behavior stimulates the application of different mathematical approaches for their analysis. After Mandelbrot works devoted to the analysis of financial markets the approach to the distribution of stocks' prices as to the fractal class but not normally distributed has become very actual. Our work is devoted to the research of statistic of fractal dimension (by Hausdorff) of the diagrams of Russian oil and gas companies stocks' prices and to the formation of an optimal investment portfolio. Preferable will be the portfolio with the least dimension. This portfolio can be interpreted as the most predictable.

Steel 20 embrittlement during continuous exploitation
http://www.ngdelo.ru/2006/1/207-214.pdf
It is shown, that in the process of the continuous high pressure vessel operation in the temperature interval of 250-550°С, a change of physical and mechanical features of the metal occur, including embrittlement, change of the structure, phase composition, toughness characteristics. It is also stated, that microstructure change and mechanical characteristics on internal and external device surfaces occurs not evenly. Herewith internal surface of the device is more subjected to degradation and embrittlement under the action of operation factors. For the changes taking place in the material during continuous vessel operation to be taken into account it is necessary to consider some changes in physical and mechanical characteristics of the metal and material tendency to embrittlement.

Change of density of emergency refusals of an operating time has the polynominal law. It testifies, that failures occur before development(manufacture) of a service life and are due to curving weariness. It is shown, that curving the weariness is connected to occurrence of shock forces at movement of the bottom part of configuration with variable acceleration on an ellipse.
