摘要
对现有工作成果资料的分析表明,湖南平江龙泉湾地热受控于北东向断裂构造F_(1)和F_(2),沿F_(1)断裂展布。通过在勘查区开展可控源音频大地电磁测深,查明勘查区构造F_(1)、F_(2)、F_(3)空间分布位置,并判断了其产状及延伸深度;建议施工钻孔ZK01,终孔深度为502.88 m;揭露断裂构造F_(1),在近终孔位置处见有热水涌出,水量较大,稳定最大流量可达1200 m^(3)/d,最高温度达44.5℃,取得了较好的勘查效果。
According to analysis of existing work results and data,the geothermal energy in Longquan Bay of Pingjiang,Hunan Province is controlled by NE⁃trending structure F_(1) and F_(2) faults and distributed along the F_(1) fault.By using controlled source audio⁃frequency magnetotelluric sounding in the exploration area,the spatial distribution positions of F_(1),F_(2) and F_(3) structures in the exploration area were found out,and their occurrence and extension depth were determined.It was suggested that drilling ZK01 should be constructed with a final hole depth of 502.88 m to expose the fault structure F_(1).There was hot water gushing near the final hole with a large amount of water,the maximum steady flow of which reached 1200 m^(3)/d,and the maximum temperature reached 44.5℃.The study achieved good exploration results.
