地球化学温标方法在地热资源评价中的应用
|
摘要
当前,主要有三种合理估算地热田热储层温度的方法,分别为直接测量法、地球化学温标计算法以及地温梯度推算法。本文运用地球化学温标计算法对青海省共和盆地恰卜恰地热区的热储温度进行估算,推断出该区第四系地下热水的热储温度范围,然后以第四系地下热水热储温度区域分布情况对第三系的相关情况进行分析,认为研究区域东部和南部的热储温度会更高,这为该地区地下热水资源的开采提供了基础资料和科学依据。
At present, there are three main methods to estimate the thermal temperature of geothermal field, namely, direct measurement method, geochemical thermometer algorithm and geothermal gradient algorithm. In this paper, the geothermal temperature scale algorithm is used to estimate the thermal storage temperature of the Qibaqi geothermal zone in the Gonghe basin of Qinghai Province, and the thermal storage temperature range of the Quaternary underground hot water is deduced. Then, The distribution of temperature region is analyzed, and it is concluded that the thermal storage temperature in the eastern and southern areas of the study area will be higher, which provides the basic data and scientific basis for the exploitation of underground hot water resources in the area.
