APPLICATION OF COMPUTER MODELS ON THE RECONSTRUCTION OF GEOTHERMAL HISTORY IN BASINS

The reconstruction of geothermal history in sedimentary basins is one of the fundamental studies for the oil/gas exploration.Since the amount of hydrocarbons generated from source rocks shows its functional relationship to the maturity and the changes of geothermal field would influence on the behavior of oil/gas in basins,the accurate reconstruction of changing process of geothermal field in basins would be favourable for the improvement of efficiency in oil/gas exploration activities.Therefore,the authors of this paper have developed a set of models to estimate the geothermal behaviors in various geological periods by using the available data from drill wells.Thereafter,it clearly reveals the thermal evolution of organic matter and reconstructs the geothermal history of basins based on the available geothermal profiles.
