| 英文摘要 | This paper presents the temperature measurements in the main hole of Chinese Continental Scientific Drilling, the variation trend of temperature gradient with depth, and systemic thermal conductivity data together with the temperature-pressure correction. Four temperature profiles indicate that the measured temperatures in four times show great differences in the shallow depth ( above 100m), but tend to be consistent downward. However, between 900 similar to 1600m, the temperatures show fluctuation again, possibly due to effects of groundwater activities. The deeper temperature in the borehole shows quite good linear relationship with the depth. In four depth ranges, 0 similar to 500m, 500 similar to 2700m, 2700 similar to 3600m, and below 3600m, the temperature gradient increases or decreases alternatively, with a mean of 24.8 +/- 3.4 degrees C/km. The thermal conductivities based on 198 core samples range from 1.711 to 3.6 W/(m . K), with an average of 2.716 +/- 0.403 W/(m . K). After temperature-pressure correction, the thermal conductivities range between 1.989 and 3.652 W/ (m . K), with a mean of 2.808 +/- 0.363 W/(m . K). The variation of thermal conductivity with depth could not compensate the variation of temperature gradient, indicating that other factors influencing temperature gradient could not be neglected. Temperature measurements and its long-period observation will provide reliable basic data for geothermal and geodynamical study of the ultra-high pressure metamorphic belt. |
