利用物探方法圈定含水破碎带和热储水层的区域分布,是地热勘查的有效手段。采用微动勘探技术,取得了某地块地热勘查视S波速度剖面,其中低速异常表征的破碎带判定为热储含水构造。结果表明,微动勘探方法对深部低速层的分辨能力较高,对破碎带等低速异常体探测效果良好,能有效圈定含水破碎带区域,有助于提高地热勘查精度,可为地热井位选址提供重要依据。

An effective method of geothermal exploration is geophysical prospecting by delineating water-bearing fracture zones and geothermal reservoirs. A microtremor survey method can be used to obtain S-wave velocity profiles across a given geothermal exploration area, with abnormal fracture zones associated with water-bearing structures and geothermal reservoirs being distinctly visible as low velocity zones. These results indicate that the microtremor survey method can accurately detect deep low-velocity zones, with fracture zones that form distinct low-velocity bodies being easily identified by this method. This method can effectively delineate water-bearing fracture zones and can significantly improve geothermal exploration accuracy, enabling accurate targeting of positions for geothermal well sites.
