Detection of fractured zones and subvertical destruction of Jurassic deposits of Povkhovskoye field

The article discusses the geological costing North Povkhovskoye site of Povkhovskoye field. Much attention is paid to the Jurassic deposits, whose potential is still poorly understood. The article addresses the issues of replenishment of hydrocarbons and the interpretation of seismic data CDP-3D. In addition, were given the methodology which is confidently distinguishes zone violation. The method is based on a dynamic analysis of the seismic field. To isolate the zones of tectonic disturbances in the Upper Jurassic deposits was used brute force technique of seismic wave field CDP-3D attributes.
Materials and methods
In the study were used the results of the dynamic analysis of the wave field on North Povkhovskoye the plot in order to distinguish the tectonic disturbance and associated areas.
Results
Zones of increased tremendously and subvertical destruction of Jurassic deposits Povkhovskoye field were detected based on the conducted dynamic analysis of seismic wave field.
Сonclusions
According to dynamic analysis of seismic wave field were determined the patterns of distribution of faults, most of which are confined to the borders of horst and grabens allocated on the surface of the basement rocks, rarely penetrating to the sedimentsof the upper Jurassic. In article was shown the high reliability the detection method of fractured zones and tectonic faults by dynamic analysis of 3D seismic exploration, which consists in iterating the dynamical attributes. Depending on the quality of seismic information and the degree of manifestation of tectonic processes are indicative of certain attributes.
