Geological structure and geoseismic criteria of petroleum prospects mapping of the Lower Jurassic formations of the Ust-Tym megadepression
DOI 10.31087/0016-7894-2018-6-81-96

This work is dedicated to the analysis of geological structure of Lower Jurassic formations in the Ust-Tymsky megadepression situated in the central part of the Tomsk Oblast, and to the development of the region-adapted geoseismic methodological approaches for geological section prediction and structurally complex oil and gas exploration targets identification in the basal J17 sand level. Regional model of geological structure and petroleum potential of the Lower Jurassic are considered in the Ust-Tymsky megadepression. Basing on integrated interpretation of seismic and deep drilling data, and using seismic stratigraphy, paleo-structural, amplitude, and regression analyses, the following work was carried out: building the detailed model of geological structure for the Lower Jurassic series in the Tolparovsky area; prediction of areal distribution and thickness of sand levels; the Tolparovsky lithologic trap is identified in J17 Horizon that occurs in the basal part of sedimentary cover.

 

Key words: Ust-Tymsky megadepression; Lower Jurassic; Togur formation; Urman formation; sand level; reflection horizon; petroleum prospect; lithologic trap.
