Опыт настройки программ оптимизационной инверсии при малом объеме априорной информации
Authors Б.Н. Еникеев and И.Я. ФлеркевичBefore doing an optimization inversion one needs to identify two main types of stochastic interrelations. The first type of interrelations shows the possibility to estimate a vector X (the required properties) by a vector Y (logging data burdened with errors). The second type allows to take into account additional equation linking the components of the vector X. The authors describe an original approach to identify parameters of interrelations using data of well tests. They create an algorithm to build a decision rule for bed classification into product-water classes by vector Y. The results of using this approach are illustrated on a specific object

Влияние геомеханических параметров среды на каротажные диаграммы ВИКИЗ и БКЗ и модель околоскважинного пространства
Authors Г.В. Нестерова, И.Н. Ельцов, Л.А. Назаров and Л.А. НазароваAdditional stress and deformation fields are occurred in the borehole environment during drilling. This process has as consequence porosity and permeability variations and change of mud filtration. Authors developed software for joint modeling of geomechanical and hydrodynamic processes around drilling and VIKIZ (induction log) and BKZ (Russian lateral log) log simulation. Impact of geomechanical parameters on distribution of water saturation, salt concentration, resistivity and logs of VIKIZ and BKZ was studied

One of the objectives of the work is: to identify ways of hydrocarbon migration and the discovery of new structural and lithologic traps shielded. Paleotectonic reconstruction of the field was carried out to verify the interpretation of the fault, the tectonic history of recovery and verification of the presence of faults on the section

Нефтегазогенерационный потенциал юрских отложений Баренцевоморского шельфа
Authors Н.М. Кирюхина, Т.А. Кирюхина and М.А. БольшаковаThe evaluation of oil and gas generation potential of all series of the Jurassic system has been accomplished based on geochemical investigation of outcrop samples from the Svalbard and Franz-Josef Land Archipelagoes and core samples from the Barents Sea wells. Besides the already proven Upper Jurassic source rocks, the shaly interlayers within the Lower-Middle Jurassic strata with considerable concentrations of the organic matter have been identified. In the SE part of the Barents Sea these rocks have good source rock properties. The Lower-Middle Jurassic shalestones from the northern Archipelagoes are characterized by low hydrocarbon index and generation potential and cannot be considered as source rocks. The authors tried to determine regularities in changes of kerogen type, generation potential and maturity of organic matter in the Jurassic rocks

Геотермический режим осадочных бассейнов мира. Факторный анализ особенностей вида термограмм
Authors С.М. Астахов and А.Н. РезниковThe present investigation deals with the temperature conditions of the world sedimentary basins. 307 equations, characterizing different types of the basins geothermal regimes have been obtained. Three dominant types of the present geothermal basin regime were determined by using factor and cluster analysis of the equations parameters. They are: 1. Anomalous geothermal regime with the probable gas flow in deep horizons; 2. Geothermal regime with the rigorous influence of magmatic intrusions; 3. Normal geothermal regime. Also it is recognized the figure of the initial thermogram close correlation with the basin geodynamic excitation. The further investigations of this problem join with the paleotemperature restoration in basin modeling order. This approach is of extremely interest because it allows more detail to predict the processes of generation in the first place, migration and accumulation into the second indirectly

Особенности геологического строения и нефтегазоносность надсолевого комплекса центральной части Астраханского свода
Authors М.Е. Дуванова and А.В. ДувановThe main searches of oil fields and gas on Astrakhan Anticline belong to podsolevy deposits, a secondary direction of searches and investigations are nadsolevy deposits, including Triassic. Open large-scale deposits of the Astrakhan gas-condensate, Central Astrakhan gas-condensate field confirmed an appreciation of prospects of a neftegazonosnost of a podsolevy complex of Precaspian Depression. However the big depths, difficult mining-and-geological conditions, abnormally high sheeted pressures, hydrosulphuric and uglekislotny aggression on the underground equipment of wells – all this results in need of application of difficult technologies and the unique equipment that involves sharp increase in cost of works at oil and gas. Therefore there is a need to return to an assessment of prospects of a neftegazonosnost of Triassic deposits as carrying out exploration on this direction won't demand such big initial expenses as it takes place for a search complex. In the territory of area 5 fields in mesozoic deposits (Promyslovsky, Beshkulsky, Severo - Shadzhinsky, Bugrinsky, Camel) with depths of productive layers in the range of 750-2700 m are revealed. By results of seismic, geophysical data and drilling, traps of a zaleganiye of Triassic deposits which are dated for muldovy zones of an osadkonakopleniye of the Inundated territory are revealed

Особенности геологического строения и перспективы нефтегазоносности средне-верхнефранских отложений Волгоградского Поволжья
Authors М.В. Махонин and П.В. МедведевThe majority of unexplored resources of Lower Volga Oil and Gas Region (336.9 million tones, 51.5%) are located within carbonates of Devonian. Statistical analysis shows that there is a chance of discovering at least 4-5 fields with recoverable reserves of 10-15 million tons of oil equivalent in Devonian carbonates. In this communication relevant further search of oil and gas fields in the carbonate sediments Devonian. Structural, paleostructural and lithofacial analysis of Volgograd’s Volga region was conducted in order to define zones and intervals favorable for generation of organogenic structures in middle and upper Frasnian. Zones that are favorable for generation of different types of organogenic structures and hydrocarbon traps, associated with them, were defined based on the results of that analysis

Authors О.О. Абросимова, К.Н. Зверинский and С.И. КулагинGas fields confined to major reef sequences have been discovered and are developed in the area of the Bukhara-Khiva petroleum region. Resource base replacement requires discovery of new moderate-size bioherms. Productive layers are possibly developed not only inside reef mounds, but also in sediment fill lows. Seismic inversion is one of the approaches to study complex carbonate reservoirs

Authors О.Н. Бредихина and О.С. ЖуковаThe oil and gas potential of the Mid-Kuril trough was analyzed and studied in this paper. The basin has all the elements of the petroleum system: source rock, reservoirs, traps. Thicknesses of sedimentary basin, depositional environment and geothermal regime suggest that migration and accumulation of hydrocarbons is not only possible, but also real

Влияние мезозойско-кайнозойских тектонических процессов на нефтегазоносность центральной части Александровского свода
Authors М.В. Соловьев, В.А. Конторович and Л.М. КалининаIn work creation of structural maps and maps of thickness of seismogeological megacomplexes of breeds is carried out. It is analysed stories of tectonic development of the central part of the Aleksandrovsky arch and adjacent territories in the Mesozoic and the Cenozoic. Connection of a heating-up period of explosive violations with oil and gas content of neocomian deposits is established. The conclusion that, despite a similar modern structural and tectonic structure of Krivolutsky and Okhteursky ramparts, the history of their formation was in essence excellent that essentially affected their oil and gas content is drawn
