ASSESSMENT OF THE OIL AND GAS GENERATION POTENTIAL OF PALEOGENE DEPOSITS IN THE WESTERN PART OF THE SANJIANG-MIDDLE AMUR SEDIMENTARY BASIN

Аннотация


The prospects of oil and gas potential of Paleogene deposits of the Sanjiang-Middle Amur sedimentary basin based on one-dimensional digital models have been assessed. The results obtained indicate that the formation of first-generation gas is predicted in both the Birofelsky and Preobrazhenovsky graben from a depth of about 1000–1300 m. The main sources of hydrocarbon generation are the deposits of the Lower Chernorechenskaya formation and the Paleocene complex. The most promising for the generation of liquid hydrocarbons is the Preobrazhenovsky graben, where oil generation is currently predicted from a depth of about 2000–2500 m.
