METHOD FOR DETERMINING MIGRATION OF HYDROCARBON DEPOSITS IN DOME STRUCTURES Russian patent published in 2021 - IPC G01V99/00 

FIELD: geological exploration.

SUBSTANCE: invention relates to the field of geology and can be used to determine the migration of hydrocarbon deposits in dome structures. Essence: by the method for track dating of apatite of the foundation rocks, the age of the foundation rocks, the age of intensive reactivation of the territory with the formation of a dome structure, the temperature of the foundation rocks, the presence of cooling of the foundation rocks are revealed. The method for homogenization of fluid inclusions in quartz and calcite of reservoir rocks of the sedimentary cover records the young dome tectonics in the region, which is associated with the intense activity of fluids, by studying gas-liquid inclusions in reservoir rocks of the deposit. The temperature range of fluid manifestation in sandstone quartz is revealed, and the foundation temperatures are taken into account. If the presence of higher temperatures in the overlying sedimentary rocks than in the basement rocks is detected, the conclusion is made about the effect of hot fluids. If the presence of a high-molecular organic compound, oil is detected in calcite, the conclusion is made about the introduction of oil by fluids from the basement rocks into the dome structures of the sedimentary cover.

EFFECT: reduction of the complexity and increase in the reliability of determining the migration of hydrocarbon deposits in dome structures.
