Abstract
The article deals with the techniques of kinematic and dynamic analysis of time sections of the common depth point method (CDPM) in combination with the data of gravity and magnetic exploration. Seismic velocity, as a petrophysical indicator of precipitation characteristics, is closely related to lithology, porosity, density, permeability, oil and water saturation. Magnetic prospecting finds application in the identification and tracing of discontinuous violations of the foundation, in predicting the distribution areas of hydrocarbon traps that are genetically related to zones of tectonic fracturing. The fracture zone is a weakened section of the section characterized by a density deficit, in the local gravity field it is reflected by negative anomalies of ∆g loc. The performed research allows the authors to conclude about the high efficiency of the proposed methods of complex reinterpretation of geophysical data in the search for oil deposits in the terrigenous devonian on the territory of Tatarstan.
Materials and methods
The work uses materials of geological exploration, in particular the results of exploration geophysics for the search for hydrocarbon accumulations. A comprehensive reinterpretation and comparison of data makes it possible to increase the probability of detecting new hydrocarbon deposits.
