Palaeotectonic analysis of the eastern part of the Khanty-Mansi Autonomous Okrug

Authors: N.V. Nassonova, S.V. Ostapenko, L.N. Ivanova, L.V. Lapina (Tyumen Oil Research Center OOO)

The analysis of the dynamics of paleotectonic development of area, covering the eastern part of the Khanty-Mansi Autonomous Okrug, is executed. A set of isopach maps is drawn and analyzed, using a surface of the reference reflective seismic horizons A, B, and G, corresponding to the boundaries of the basic structural-formational megacomplexes of sedimentary cover and the surface of pre-Jurassic formations. The main stages in the formation of the topography of the eastern part of  Khanty-Mansi Autonomous Okrug and the basic regularities of oil and gas content are revealed.
