The article considers the features of the gasometric survey and seismic exploring results on the regional geophysic profile in territory of the large geostructual blocks on south-eastern part of Russian platform: Voronezh anticlise, Rjazano-Saratov’s deflection and Zhiguljov-Pugachov deflection. It selected testes of gas from 2m depth there are metan, its gomologes, hydrogen, gelium. In gas anomalies the fractured tectonic and geostructured elements reflected. Its presents the oil-gas prospecting interest.

The questions need physical and geological modeling in solving inverse problems of geophysics and the notion of a coherent FGM. The key provisions of the agreed methodology seysmogravimetricheskoy FGM, grounded approach to seysmogravimagnetic modeling and provides examples of its implementation

This article focuses on the problem of improving seismic data reliability of seismic data during oil and gas exploration. As one of the most effective ways to solve this problem, the authors consider the application of polarization filtering. For its practical implementation it is offered to use new adaptive technology. It is characterized by high technological effectiveness, advanced capabilities to allow peculiarities of reflectors polarization and interference waves in specific seismogeological conditions.

In the established practice of geological exploration for oil and gas conclusions about the facies belonging of the rocks of oil and gas basins and individual exploration areas were made mainly on the basis of the study of core material. Recently for this purpose the results of seismic exploration and well logging have been used. Geophysical methods despite their obvious progress are indirect and intermittent core sampling and incomplete coring make facies analysis difficult.

Geological and geophysical modeling is a modern and classic method of processing and interpretation, which is relevant in the segment of geological exploration of any geophysical method. The article presents the material of two-dimensional modeling based on the results of gravity and seismic exploration in the licensed areas of the Saratov region.
