Geotemperature 2D-models of cenozoic hydrocarbon generation centers of the Sanjiang- Middle Amur basin

The oil and gas potential of the Cenozoic deposits of the Sanjiang-Middle Amur sedimentary basin was assessed on the basis of two-dimensional spacial-temporal digital models. The obtained results show that favorable conditions for gas formation are in the southwestern part of the Pereyaslav graben, while both oil and gas formation is characteristic of its northeastern part. The Birofeldsky and Chernorechensky centers in the Cenozoic complex of the Pereyaslavsky graben are the main sources of hydrocarbons. Cenozoic deposits within the Nongjiang graben currently also generate hydrocarbons.
