最近,德国的地质物理学家开发出了一项名为“双井抽、注水交换循环”的地热利用新技术。德国东北部地区处于北德盆地,地下深处有许多沙岩层构造。这种像海绵一样多孔的地质构造中含有大量热水,在有些地区温度可达98℃。这种沙岩层构造往往又被一种泥质脉岩包裹着,其极好的... Recently, geophysicists in Germany developed a new technique for geothermal utilization called “double-well pumping, water exchange cycles”. The northeastern region of Germany is in the North German basin, with many sandstone formations deep underground. This sponge-like porous structure contains a lot of hot water, in some areas the temperature can reach 98 ℃. This sandstone formation is often surrounded by a muddy veins, its excellent ...
