On the expression of oil and gas-bearing structures of the East and Central Pre-Caucasus in the buried relief

Abstract

Analysis of the materials of deep boring and seismic sounding by ancient stratigraphical gaps of a number of oil- and gas-bearing structures allows arriving at a conclusion of primary distribution of inversion paleomorphostructures on the boundary of big continental interruptions in the East and Central Pre--Caucasus. The inversion degree of paleorelief is stipulated, first of all, by activity of tectonic processes, lythological factor plays but a passive role. Terrigenic sediments that fill paleovalleys can serve as lythologically and stratigraphically screened traps for oil and gas deposits. Some regularities of expression of oil- and gas-bearing anticlinal structures in the buried relief given in the paper are of great importance for geological prospecting.
