摘要
五莲地表岩性为花岗岩,选用AMT和CSAMT进行综合勘探。AMT测线控制控水断层走向及倾向,CSAMT法圈定断层交汇区域,圈出地热井ZK001,后期钻探结果符合物探预测,涌水量2600 m^(3)/d,出水温度为75℃,可利用热能量为2.362×10^(8) MJ,开采一年所获得热量相当于煤炭储量8059.34 t。
The surface lithology of Wulian is granite,and AMT and CSAMT are selected for comprehensive exploration.AMT survey line controls the strike and tendency of water control fault,CSAMT method delineates fault intersection area,and geothermal well ZK001 is delineated.The later drilling results are in line with geophysical prediction,with water inflow of 2600 m^(3)/d,outlet water temperature of 75℃,and available thermal energy of 2.362×10^(8) MJ,and the heat gained by mining for one year is equivalent to 8059.34 t of coal reserves.
