Abstract


The work analyzes one of the most important and complex stages of constructing geological models of the Kharampur field, which directly affects the process of calculating hydrocarbon reserves, planning the process of developing oil and gas deposits, as well as assessing promising zones - the creation of a structural framework. Seismic and geological correlation of layers affects, first the geometrization of known deposits and the distribution of promising oil and gas zones.
The complexity of modeling the structure of the Pokur deposits is associated with the predominantly continental genesis of the deposits of the Pokur strata, which determines their high geological heterogeneity and lateral variability of the section, which is reflected in seismic sections. The article describes the process of correlation of productive strata of the Pokur formation of continental origin, the methodology of seismic calculations, as well as an algorithm for modeling the structural basis of the pokur deposits.
