Abstract
The subject of study and research of seismic artifacts, which include the study of abnormal seismic records is related to the history of tectonic development, fluid dynamic processes in the sedimentary cover interval, distribution of the thermobaric effects from formation fluid flow, upflow hydrocarbon migration and other features of the evolution of the Earth’s crust. On the territory of Western Siberia and the Kara Sea basin there is a wide development of abnormal forms of seismic record in the form of abnormal ring structures (ARS), also called inverted ring structures (IRS), fluid dynamic abnormities (FDA). ARS are vertically extended ring-shape of wave field deformation. The most complete study of the identified ARS by 3D seismic data. A lot of statistics data of such kind of abnormal antiforms accumulated at the present time. There are still many questions about cause and effect relationship of such artifacts with the secondary hydrocarbons migration mechanism, formation and accumulation hydrocarbon deposits, impact on vertical and lateral hydrocarbon migration intensity, the abnormal high pore pressures occurrence. One of the trends of seismic interpretation is studying of fluid dynamic abnormalities of seismic record and the relation with oil and gas potential in the sedimentary basin. In the article, the attempt is to establish to identify the correlation between various forms of fluid dynamic structures (FDS) with time and the stages of deep formation fluids migration occurrence. It is possible that the allocation of new types of hydrocarbon deposits of fluid dynamic type may be associated with ARS. It is still a hypothesis. But the presence and analysis of seismic attributes allow us to make this suggestion. What is positive is that all ARS studied by drilling related to the multi-bedded deposits. Identification and studying ARS patterns of relations with the mechanism of formation and accumulation hydrocarbon deposits allow us to conduct exploration geological prospecting works more efficiently, estimate correctly geological risks, rank and identify the most prospecting areas for exploratory drilling. The practice of prospecting of recent years has shown the accuracy and informatively of this trend as an indicator of petroleum potential.
