The role of overpressures in thermochemical processes in the South Caspian basin is considered. The studies, which take the world experience into account, suggest that the South Caspian basin (mainly its deep-water part), as well as other basins with abnormally high fluid pressures, is characterized by retarded kerogen and oil cracking and reaction of clay-mineral transformation. These processes can be periodically intensified by the development of diapirs and mud volcanoes, which are centers of pulsed hydrocarbon discharge from the system. The conclusion is made that deeply buried deposits in basins with fluid overpressure are promising in terms of hydrocarbon pools. 相似文献

Using Shen’s method (Shen et al., 1996), deformations of the Earth’s crust in Azerbaijan were studied based on GPS measurements. For estimating the rate of deformation, we used the field of velocity vectors for Azerbaijan, Iran, Georgia, and Armenia that were derived from GPS measurements during 1998–2012. It is established that compression is observable along the Greater Caucasus, in Gobustan, the Kura depression, Nakhchyvan Autonomous Republic, and adjacent areas of Iran. The axes of compression/contraction of the crust in the Greater Caucasus region are oriented in the S-NE direction. The maximum strain rate (approximately 200 × 10?9 per annum) is documented in the zone of mud volcanism at the SHIK site (Shykhlar), which is marked by a sharp change in the direction of the compression axes (SW-NE). It is revealed that the deformation field also includes the zones where strain rates are very low approximating 5 × 10?9 per annum. These zones include the Caspian-Guba and northern Gobustan areas, characterized by extensive development of mud volcanism. The extension zones are confined to the Lesser Caucasus and are revealed in the Gedabek (GEDA) and Shusha (SHOU) areas, as well as in the zone located between the DAMO and PIRM sites (Iran), where the deformation rate amounts to 100 × 10?9 per annum. It is concluded that the predominant factor responsible for the eruption of mud volcanoes is the intensity of gas-generation processes in the earth’s interior, while deformation processes play the role of a trigger. The zone of the epicenters of strong earthquakes is correlated to the gradient zone in the crustal strain rates. 相似文献

A global database of gas composition and methane stable isotopes of 143 terrestrial mud volcanoes from 12 countries and 60 seeps independent from mud volcanism from eight countries, was compiled and examined in order to provide the first worldwide statistics on the origin of methane seeping at the earth's surface. Sixteen seep data were coupled with their associated subsurface reservoirs. 相似文献

In the paper, the subduction of the South Caspian microplate beneath the continental lithosphere of Central Caspian is substantiated based on the GPS measurements, crustal density model, seismological data, and seismic section along the Elburs–Apsheron–Balkhan Sill regional profile. In this context, the geodynamical model is suggested for the formation and spatial distribution of the oil and gas fields in the South Caspian Basin (SCB). It is shown that the heterogeneous oil-and-gas saturation of the sedimentary section within the South Caspian Depression (SCD), which was revealed by the long-term prospecting and exploration works, is, according to the suggested model, controlled by the subduction zone. The developed geodynamical approach to the problem of the formation of hydrocarbon deposits in the South Caspian Basin calls for rethinking the strategy of further prospecting for hydrocarbons in this region. 相似文献

The paper presents results of the comparative analysis of organic matter (OM), mineralogical characteristics, and radioactivity in Oligocene clayey rocks from the Greater Caucasus and Talysh, which bound the South Caspian Depression on the southeast and northwest, respectively. It is established that Oligocene clays of the Greater Caucasus and Talysh substantially differ in terms of quantitative and qualitative parameters of OM, its maturity, integral radioactivity, and composition of radioactive elements. At the same time, the mineral composition of clays from these mountainous massifs shows a certain similarity. It is concluded that the Fore-Talysh subsidence zone and adjacent areas of the Caspian Sea are characterized by a lower oil and gas potential as compared with Oligocene rocks developed at the southeastern margin of the Greater Caucasus.__________Translated from Litologiya i Poleznye Iskopaemye, No. 4, 2005, pp. 430–439.Original Russian Text Copyright © 2005 by Feyzullayev, Kheirov, Ch.
