| 中文摘要: |
| 通过在贵州省清镇市卫城镇西门村开展可控源音频大地电磁法测量工作,查明了地下电性结构的分布情况,查明了导水导热构造的产状及延深情况,设计了探采结合地热井(设计井深2400 m)1口,经钻探工程的验证,终孔深度为2358.08 m,终孔层位为寒武系金顶山组页岩中,降压试验最大流量为1144.08 m3/d,静水位埋深121.8 m,动水位埋深192.1 m,出水量大大超出业主要求的400 m3/d的水量；井口水温59℃,高出业主要求的42℃的水温,取得了较好的勘查效果。 |

| By measuring work with controlled source audio-frequency magnetotelluric in Ximen village, Weicheng town, Qingzhen city, Guizhou Province, find out the distribution of the underground electrical structure, the occurrence and deepening situation of water thermal structure, designed a geothermal well(design depth 2400 m) combining exploration with mining, it has been verified by drilling engineering, hole depth of 2358.08 m, the final hole horizon in Cambrian Jindingshan Formation, step-down test maximum flow is 1144.08 m3 / d, static water depth of 121.8 m, dynamic water depth of 192.1 m, water yield well beyond the owners requirement of 400 m3 / d of water; The water temperature at the wellhead is 59℃, which is higher than the 42℃ required by the owner, and with good exploration results obtained. |
