| 英文摘要 | The Karst dolomite is widely developed in Niutuozhen uplift, and the groundwater convection within this formation results in the abnormally high temperature field within the near-surface sedimentary layers, which the geothermal gradient can even reach 50.0 degrees C . km(-1). However, with the increase in/of the high permeability formation thickness, the geothermal gradient within the sedimentary layer decreased gradually. Based on the 6 boreholes temperature logging and 213 core samples thermophysical parameters measurement, the temperature distribution influenced by heat convection within the karst formation was studied by using the hydrothermal coupling. The results show that when the high permeability formation thickness is a constant, the temperature disturbance influenced by heat convection will decrease with the increase in the formation buried depth. When the high permeability formation thickness is 2.0 km, the temperature influenced by groundwater convection was 3.0 km around. Moreover, when the high permeability formations buried depth is a constant, the greater influence on the temperature distribution will occur with the increase in the formation thickness. After the measurement of borehole temperature of the An01, the temperature field of the metamorphic formation can be obtained. The geothermal gradient was 18.6 degrees C . km(-1), multiplying by the thermal conductivity value, the basal heat flow within the upper metamorphic layer was 58.2 mW . m(-2). After accumulating the heat flow value contributed by the radioactive heat production from the overlying formation, the surface heat flow value was 59.6 mW . m(-2) for the Niutuozhen area. Compared with the heat flow value 90.0 mW . m(-2) within the sedimentary layer, which was greatly influence by the groundwater convection or heat refraction, the surface heat flow value 59.6 mW . m(-2) can more accurately reflect the thermal state of this area. |
