荆门市十里牌地下热水形成的同位素研究

Isotopic Study of the Formation of Geothermal Water in Shilipai of Jingmen City

在概要介绍十里牌地热田区域地质构造背景的基础上,通过水中同位素的组成研究表明,十里牌地下热水起源于大气降水,大气降水从补给到形成地下热水,经历了长时间的深循环加温过程,由于人类工程活动的影响,地下热水在由深部向上部的运移过程中混入了大量冷水,在以后的开发利用中,必须注意地热田的地质环境保护工作。

Based on the regional geology and structure background of geothermal field in Shilipu, the research on the composition isotopic of water show that geothermal water originates in atmospheric precipitation. Atmospheric precipitation supplies and forms geothermal water through a long cycle of heating process. Geothermal water sneak into a great deal of cold water in the process of migration from deep to upper because of human engineering. It must pay attention to protect geological environment in the latter development and utilization in geothermal field.
