黄河三角洲地区地热资源及其开发利用前景初析

黄河三角洲地区蕴含着丰富的中低温地热,为2000m以浅经济型地热资源,经计算,全区地热资源总量折合标准煤相当于125×10~8t,其中仅地下热水总储存量就达到4570×10~8 m~3,可开采储量超过750×10~8 m~3,至少可以开采100a。如果形成以东营、河口、孤岛、广饶为中心的4个大面积系统的开发利用体系,并注重地热资源的综合利用和梯级利用,对于缓解能源紧张、促进经济的可持续发展等方面具有重要的意义。

Primary Analysis on Geothermal Resource and Its Exploration and Utilization Future in Huanghe Delta Area

There is rich medium-low temperature geothermal resource in Huanghe delta area, which belongs to shallow economical geothennal resource under 2 000 m. Through measurement, total amount of geothermal resource is equal to 125x109 t standard coal. Among them, underground geothennal reserve is 4 570 x 109 m3, workable reserve is more than 750x 109 m3, which can be explored more than 10 years. If an exploration and utilization system is formed, in which Dongying, Hekou, Cudao and Guangrao are its center, and more attention is paid on synthentic utilization of geothermal resource, it can lessen energy source urgency, promote investment environment, and improve continuous development of economy.
