Abstract

This article highlights the results of research to identify factors influencing the formation of oil and gas deposits within the Bukhara-Khiva region. Oil and gas accumulation is subject to a certain cyclicity, when the cycles of tectonic development: subsidence, uplift and stabilization of the tectonic regime correspond to cycles of fluid formation and accumulation. The movement of fluids does not occur during periods of downward tectonic movements, but during active upward tectonic movements, during periods of active tectonic activity. With tectogenesis of a positive sign, the mass of strata that have undergone uplift splits into cracks having certain (countable) parameters: direction, orientation, volume, etc. As an example, the article presents the results of structural interpretation of the Shurtan site, which in terms of intensity and depth of dissection differs sharply from the adjacent areas. On the deciphered detailed lineament network of the Shurtan uplift, a number of features of the lineament network were noted, characterizing its high heterogeneity and the special intensity of the new tectonic regime of the field. Supposably, these lineament zones provided vertical migration of gas into the primary porous-permeable reservoirs of the reef massif and possibly formed additional volumes of secondary superimposed zones of tectonic fracturing in dense rocks.

Key words:

lineaments, fluid saturation, faults, fracturing, localization, oil content, structures, seismic, objects
