This paper gives a review of oil and gas resource potential of the North Caspian petroleum province. A new potential for finding several giants and large-size discoveries exists, respectively, in the presalt and postsalt sequences. Recommendations for future directions in exploration targeting at postsalt deposits (Upper Permian–Triassic and Jurassic–Paleogene petroleum systems) are given. It is emphasized that, given adequate exploration techniques, the postsalt sequence may provide stable and commercial production for decades. Most of the prospects are located within nonlicensed area. Therefore, the future exploration activity will have to be implemented through special-purpose governmental projects, namely, state-funded integrated projects aiming at investigation of the individual petroleum regions and zones.  相似文献

The Karatau–Talas–Ferghana Fault (KTF) extending for 1500 km from Turgai to western Tarim is one of the world’s largest intracontinental strike-slip faults. This paper overviews the evolution of the KTF, providing insight into its relatively poorly studied northern segment in the Karatau Range and Turgai, known as the Main Karatau Fault (MKF). The right-lateral strike-slip along the KTF developed during three stages in the late Permian–Triassic, Early–Middle Jurassic, and late Cenozoic. The total strike-slip decreases northward from 200 km in the Ferghana Range to 100 km in the Karatau Range and decreases to zero in southern Turgai. Kinematic analysis of Jurassic grabens compensating the strike-slip in southern Turgai shows that strike slip along the KTF in the Jurassic, previously regarded as insignificant, actually measures tens of kilometers and 50% of the total strike slip in the northern segment of this fault.  相似文献

The Astrakhan Arch region contains one of the largest sub-salt structures of the Pricaspian basin, where perspectives for hydrocarbon generation and accumulation in the Devonian to Carboniferous deposits are considered to be high. The paper addresses the problem of structural and geothermal evolution of the region deformed by salt movements. Initially, we developed a model of the regional structural evolution along a geological profile using the volume-balancing and back-stripping methods and geological constraints on the sedimentation, erosion, and paleo-water depths. Then we developed geothermal models (along the study profile) associated with the regional structural evolution. The models were constrained by the temperatures measured in four deep boreholes along the profile. We show that the present temperatures and heat flux are influenced by the presence of salt diapirs. Since the Early Carboniferous and till Middle Permian times, the temperatures predicted by the models vary significantly due to the regional transgression and the presence of seawater. The temperature of Devonian–Carboniferous carbonates increases since the Late Permian (time of post-salt deposition) and attains its maximum values in the SW-part of the profile. If the model assumptions concerning the constant vertical and zero lateral heat fluxes are valid, we can conclude that hydrocarbons are most likely to be generated in the SW-part of the region for the post-Early Permian time.  相似文献

It is shown that the Crimea, Caucasus, and Kopet Dagh fold systems make up a single whole unified by a lithospheric strike-slip fault zone of concentrated dislocations. The strike-slip fault that dissects the sedimentary cover and consolidated crust is rooted in subcrustal layers of the mantle. The notions about strike-slip dislocations in the structure of the Crimea–Kopet Dagh System are considered. Comparative analysis of structure, age, and amplitude of strike-slip fault segments is carried out. The effect of strike-slip faulting on the deep-seated and near-surface structure of the Earth’s crust is considered. Based on estimation of strike-slip offsets, the paleogeography of Paleogene basins is refined; their initial contours, which have been disturbed and fragmented by slipping motion strike-slip displacement, have been reconstructed.  相似文献

The available geological data on the Meso-and Neoproterozoic rocks in the north of the East European Platform are considered, involving the results of a comprehensive study along regional seismic profile I-I that extends for 460 km and crosses the main structural units of the Mezen Syneclise from SW to NE. Many previously unknown structural features of aulacogens filled with thick (up to 4–8 km) sequences of the Meso-and Neoproterozoic sedimentary rocks that make up the preplate complex are demonstrated in this profile. The Riphean rocks are subdivided into three seismostratigraphic sequences: the lower part of the Lower Riphean, the Lower-Middle Riphean, and the Upper Riphean. The geodynamic events in the north of the East European Platform are correlated with those that occurred in its central part and the adjacent foldbelts.  相似文献

With the use of the method of complete geological reduction, it has been shown that the unique gravity anomaly that frames the Near-Caspian petroliferous basin in the south is related to the Lower Paleozoic volcanic-terrigenous complex that occurs at the base of sedimentary cover at a depth of 8–12 km. This complex was formed contemporaneously with spreading of the Ural-Turkistan ocean and mark a rift zone in the south of passive margin of the East European continent. The rift was conjugated with an ancient triple junction on the floor of the Ural-Turkistan paleocean.  相似文献

Recent lithological and geophysical studies of Riphean and Lower Vendian sedimentary rocks in the Kresttsy and Mid-Russian (Soligalich) aulacogens resulted in the recognition of four stages in the evolution of the East European Platform in the Late Proterozoic: (1) late Early Proterozoic–Early Riphean stage (formation of the protoplatform cover); (2) Middle Riphean stage (rifting only at platform margins); (3) late Middle Riphean–initial late Riphean stage (formation of the paleoplatform cover related to the existence of the epi-Grenville Rodinia supercontinent, which united all continents of the Earth at that time); (4) latest Riphean–early Vendian stage (rifting and origination of the Central Russian aulacogen system during the breakup of Rodinia and Cadomian orogeny.  相似文献
