Оптимизация методов построения геологических моделей на основе использования принципов сейсмофациального анализа
More LessIn spite of the constant development of technologies of geophysical methods and in particular seismic exploration, for achievement of positive results at all stages of searching of minerals, an important task is authentic interpretation of data received as a result of application of one or the other method. In this article the way of rational application of a method of the seismic facies analysis is offered in process of interpretation of seismic data. For this purpose was developed the detailed scheme of application of a method of the seismic facies analysis in which some main stages were marked out. For confirmation of the practical importance, was carried out the interpretation of seismic data on the Lobodinsky and Southern-Kislovskoy areas located within the western board of Precaspian Depression by a method of the seismic facies analysis according to the scheme mentioned above. The construction of authentic geological model and marking out of several earlier not revealed structures in productive deposits P1ar became the result of the carried-out works.

Обнаружение дизъюнктивных нарушений по аномалиям магнитного и гравитационного полей
By А.А. ЧерновHC traps are confined to jointing raised zones, controllability of traps by disjunctives does the problem of the discovery and mapping of faults solely important. As a rule, deposits sections possesses it is enough contrasting by density distribution. Directions and locations of tectonic disjunctives general zones are forecasts by potential fields anomalous. Naturally that different transformations of the field with that or other parameter find explosive disjunctives by different depth and length, confining to different structured levels. Thereby, problem of mapping faults zones gains paramount importance at searching for HC traps, their usages and prevention of its negative consequence

Выделение литологических разностей и емкостных свойств карбонатных пород в разрезах скважин
Authors В.Н. Бабов and С.М. ШевченкоThe resume of theses. Methodological instructions are lied in the basis of algorithm[6]. The algorithm is based on different influence of lithology on TNNL,GGL,AL.methods and let to divide carbonate rocks to limestones, dolomites and dolomitzed limestones and to point reservoir properties of the rocks. The main distinction of this method is that from rhe beginging you should point the lithological identity of the rocks and after this you should do the calculation of porosity and also the refuse of introduction of amendments for clay content.This is achived by using of main parameters, calculated for real composition of the rocks (mixture of limestone -dolomite)

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

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
