| 中文摘要:地热作为一种绿色能源，具有分布广、无污染、易开发利用等优点，在供暖、旅游、温泉洗浴、医疗保健、种植养殖等领域具有不可替代的作用。贵德地区地处“三江源”地区，地热资源开发利用将对“三江源”地区生态环境保护起到一定作用,通过对贵德盆地DR1地热井深井内热交换工艺，使该井出水温度由41 ℃提高到46 ℃，实现了利用井底高温岩石自行热交换方式提高地热井出口温度的目的。同时，为类似地层地热增温提供了示范。 |

| Abstract:With the advantages of green, clean and easy exploitation, geothermal energy is widely distributed and has irreplaceable role in the fields of heating, tourism, spa bath, health care and cultivation & breeding. Guide area is located in the “Source of Three Rivers” area, the development and utilization of geothermal resources will play a role in ecological environment protection there. Heat exchange process was used in DR1 deep geothermal well in Guide basin, the water outlet temperature increased from 41℃ to 46℃, the outlet temperature of geothermal well was risen by self heat exchange of high-temperature rocks at the bottom, which can be reference for geothermic warming in similar strata. |
