Predicting the Temperature Field of Hot Dry Rocks by the Seismic Inversion Method

Hot dry rocks, as clean and abundant sources of new energy, are crucial in the restructuring energy. Predicting temperature field hot rocks is great significance for trapping target areas rocks. How to use limited logging data predict within a work area difficulty faced rock exploration. We propose method (using seismic inversion results). The relationship between porosity transverse wave velocity was established with petrophysical modeling. difference calculated from density incorporated results find thermal expansion field. applied Gonghe Basin. showed that northeast higher than southwest at same depth, depth 150 °C reservoir shallower. storage cover analyzed geological stratigraphic northeastern part thicker southwestern had better insulation, which consistent prediction
