| 摘 要： | 漳州热田是我国东南沿海地区目前所见温度(121.5℃)最高的一个。热田地热地质、地球化学以及地温场的研究结果表明,漳州热田属于深循环对流型热田。为了计算热田的热水循环深度,本文采用管道模型的方法,利用热田中心钻孔的测温资料计算地下热水上涌的流速,利用热田内水化学资料计算热储温度,然后用图解法求出漳州热田热水的循环深度为3.4—4.0 km,为漳州热田的成因分析和热水资源的评价提供了依据。

| Abstract: | The Zhangzhou Geothermal Field is one of the highest temperature geothermal fields so far discovered on SE coast of China. Geological, geochemical and temperature pattern studies indicate that the Zhangzhou Geothermal Field belongs to a deep circulating thermal water field of convective type. For calculating the circulation depth of thermal water, a cylinder model was applied in the study. Firstly, the upwelling flow rate of thermal water along the cylinder was calculated from the temperature measurements in boreholes located in the central part of the field. Secondly, reservoir temperature was determined from the geochemical parameters of the thermal water. Finally, a value of about 3.5 to 4.0km for thermal water circulation depth in the Zhangzhou Geothermal Field was obtained by using a plot method. This value is used for genetic analysis and thermal water resource assessment in the Zhangzhou Geothermal Field. |
