摘要
漳州地热系统属对流型地热系统.漳州热田是我国东南沿海地区目前所见热田中温度最高(121.5℃)的一个.地表热流值的研究表明,热田中心具有最大的实测热流值(359mw/m^2).本文根据热田内152个钻孔的测温资料和56块岩石样品的热导率数据,采用三种不同方法计算出漳州热田及其邻近地区的大地热流值,并讨论了热流值分布的特点.
Zhangzhou Geothermal Field is the highest in temperature one so far discovered in southeastern coastal area of China and belongs to 'convective type'. Observed highest temperature in drillholes exhibits 121.5℃ at a depth of 90 m. Heat flow studies indicate that the highest heat flow is observed in the central part of the Field, which has been recognized to be the discharge area of the Zhangzhou Basin. Based on 152 temperature measurements in boreholes and thermal conductivity determinations on 56 rock samples, heat flow values in different parts of the Field have been calculated by using 3 different approaches. The characteristics of heat flow distribution in Zhangzhou Geothermal Field were discussed in this paper.
