Spatial Correlation of Gas Fields Nizhneangarsk Petroleum District with the Deformation Anomalies of the Gravitational Field

The report deals with a new type of structural anomalies of the gravitational field - zones of stretching near shifts. Zones were isolated by the original method gravistructural analysis, which based by the study of azimuthal dispersion the field. The method allows to solve two geodynamic problems. First, the spatially divided right and left shifts and, secondly, to identify areas of compression and extension near shifts. Irrespective of the geological data, the study allowed set kinematic type of major deep faults of Nizhneangarsk petroleum district , as well as set the width of their dynamic influence. Also found a direct spatial correlation of zones of stretching near shifts and gas fields. Mapping these zones allows to predict the promising areas prospecting of hydrocarbons.
