New data on the geological structure of the gas Aral-Kyzylkum shaft

Abstract

Shaft-like structures that host petroleum deposits were studied within the Epi-Paleozoic plates using seismic methods. This study is very topical, as it revises existing ideas on the geological structure and tectonic position of the Aral-Kyzylkum shaft and presents the author’s 3D model of this structure, which was constructed on the basis of interpretation of 2D seismic data. It was established that tectonic uplift of the Aral-Kyzylkum shaft is an Alpine positive structure, which was initiated above the Early Cimmerian system of grabens in the modern strain field. This revision allowed us to propose a new model of petroleum structures of this type and estimate the possibility of using structural-geological approaches to an analysis of their petroleum potential.
