Thermic Environment and Thermal Evolution of the Sedimentary Cover in the Astrakhan Oil-and-Gas Province
摘要
Abstract
Data on the temperature and heat flow distribution in the sedimentary cover of the Astrakhan arch in the Caspian Basin are considered. Depth temperatures in 2D and 3D models with the thermal tomography technology are carried out. Parameters for this calculation are represented by original data on the thermophysical properties of sedimentary cover rocks and the concentration of long-lived isotopes in rocks. Palinspastic reconstructions of the sedimentation history of the cover served as the basis for calculating the temperature evolution over 400 Ma.
