天水街子温泉通过可控源音频大地电磁测深,在温泉所在的温家峡及其附近深部发现的低阻电性层呈层状分布,其深度与以往钻孔中所见地下热水部位一致,推断此低阻层为热水通道。结合地表地质和地面磁测推测逆断层与上盘推覆体(牵引背斜)构成推覆构造,逆冲断层为阻水构造,活动上盘岩块破碎和裂隙发育是地下热水良好通道,控制着中低温地热田分布。街子温家峡温泉和黄家峡有利热储地段,地下热水具有充沛的补给来源、较好储存和开采条件,具有进一步钻探开发扩大地热利用的远景。 Tianshui Jizi Hot Spring, through controllable source audio frequency electromagnetic sounding of the earth, presents a layered distribution of low resistivity electrical layers found in and around the Wenjia Gorge in which the hot springs are located. The depth is similar to that of the underground hot water sites Consistent, infer that this low resistance layer is a hot water channel. According to the surface geology and the ground magnetic survey, it is inferred that the thrust fault and the overthrust nappe (traction anticline) form a nappe structure, the thrust fault is a water blocking structure, the rock fragments on the movable upper plate are broken and fracture development is a good channel for underground hot water, Control of low-temperature geothermal field distribution. Street Wenjiaxia Hot Springs and Huangjiaxia favorable thermal storage lot, underground hot water with abundant sources of supply, better storage and mining conditions, with further exploration and development to expand the use of geothermal prospect.
