Key section of the Preobrazhenka productive horizon in the Vendian-Lower Cambrian carbonate complex (Lena-Tunguska petroliferous province)

摘要

We present results of lithofacies, reservoir, geochemical, well logging, and petrophysical studies of the key section of the Vendian-Lower Cambrian Preobrazhenka productive horizon in the Lena-Tunguska province. We have considered the composition, structure, and formation conditions of the deposits as well as the intensity of postsedimentation processes and the rock geochemistry, petrophysics, and reservoir properties.
