Analysis of the influence of the tectonic factor on the placement of oil and gas deposits of Fergana depression

Abstract

The article presents the results of studying the relationship between the distribution of oil and gas fields with tectonic factors. It is shown that the quantitative distribution of hydrocarbon deposits depends on the type of neotectonic elements: the maximum falls on stepped zones (31%) and monoclines (22%). In fault zones - 10-15%, in anticlinal zones, uplifts and depressions - 5-7% of the total number of deposits. Based on the analysis of variance, it was found that the strength of the influence of the amplitude of neotectonic movements on the formation of effective volumes of oil, oil and gas and gas deposits is about 40-50% of the total amount of influencing factors. Two independent intervals of the amplitudes of the neotectonic movements, which differ in the nature of the dependence, are noted.
