METHOD FOR SEARCHING FOR HYDROCARBON DEPOSITS Russian patent published in 2021 - IPC E21B49/00 G01V9/00 

FIELD: oil and gas industry.

SUBSTANCE: method for searching for hydrocarbon deposits is claimed. The method for searching for hydrocarbon deposits includes the selection of rock samples from oil and gas bearing areas in the process of drilling. Selection of sites concentrated in the sedimentary cover. Sampling from these sites. A site above volcanic plateaus near fossil rifts is chosen as the sites concentrated in the sedimentary cover. Sampling is carried out with the establishment of zones with paleotemperatures of 80-160°C according to the reflectivity of vitrinite, in which the paleotemperatures of homogenization are detected according to gas-liquid inclusions of hydrothermal minerals. The level of paleogeothermal mismatch is calculated, which is equal to the ratio of the maximum paleotemperatures of homogenization of gas-liquid inclusions to the paleotemperatures calculated on the vitrinite scale, and if the level of paleogeothermal mismatch is exceeded by more than 1.4 times, the presence of hydrocarbon deposits is judged.

EFFECT: increasing the reliability of the forecast.
