| 摘 要： | 天水地区地热资源丰富，对皂郊地热田采用地面物探、地热钻探、采样测试等多种勘查方法进行勘查，通过较为完整的地质资料分析，对地热田地热赋存特征、水化学特征及地热田的形成条件进行了论述，认为该地热田为受断裂构造控制的中低温Ⅱ-2型地热田，属低温地热资源，热流体属于温热水级别，地热田规模为小型，为下一步在天水及周边地区断裂带寻找地热资源提供借鉴。

| Abstract: | Based on analysis of relatively complete geological data derived from various geophysical methods, geothermal drilling, sampling and testing in the exploration process of geothermal field in Zaojiao Town, it has been concluded that fault structure is a main tectonic genesis of the geothermal field, a type-II geothermal area at medium-low temperature, which belongs to low-temperature geothermal resources. The thermal fluid is at warm-hot level, representing a small-size geothermal field. Then, it has been discussed that occurrence characteristics of geothermal energy, hydrochemical features, and formation conditions of this geothermal field. So, the results of the paper can provide us with contributions to the next step of finding geothermal resources in the fault zone of Tianshui and its surrounding areas. |
