Geothermal condition is one of the main controlling factor for hydrocarbon occurence and their evolution. This is the essential basis that geothermal studies can be used as a effective method to evaluate and forecast the oil-gas resources.
    Since geothermaltechnique was introduced into oil一gas research domain，systematic studise of geotemperature，palaeo-geotemperature，terrestrial heat flow and thermal evolution history of oil-gas district and combined with other geological conditions of oil-gas genesis have manifested their significanoe in oil-gas resources assessment and prediction.  It is great progression of oil-gas studies as well.We may well say，geothermal method have broad prospects in oil-gas resources studies.
