| Abstract: | That the free radicals increase during the evolution of kerogen, which may result to the variation of the electron Paramagnetic resonance（ERP） spectra, is the basis of free radical density（Ng） being used as thermal index. In this paper, three kinds of methods by using EPR-kerogen method to study paleogeo-temperature of sedimentary basin were discussed. Paleogeothermal gradient of Well TZ1 from Basin were estimated by using the Ng-depth Curves and the variaion history of heat flow of the single well in Qiongdongnan Basin, the South China Sea, was inversed, too, modelling computation combining measured density of free radicals of kerogens. |
