摘要
云南省宜良盆地内的房地产开发需要进行地热资源勘探,盆地内地热热储层为震旦系上统灯影组,热储深度大,地热勘探比较困难,一般物探方法难以解决大深度勘探问题,因此选择用高频大地电磁法进行勘探。通过高频大地电磁法勘探,并对勘探结果进行解释,圈定了热储层,预测了热水贮存位置,经钻探验证,在1290~1450m见到热水,与物探推断结果相吻合,取得了良好的应用效果,对今后大深度地热勘探有参考意义。
Geothermal resource will be explored for the real estate development in Yiliang Basin of Yunnan Province. The storage layer of geothermal resources in Yiliang area lies deeply in Dengying Formation, Upper Sinian system. High frequency magnetotelluric method is employed to explore the geothermal resources for the common methods cannot be applied at such a depth. The geothermal resource is located after analysing the high frequency magnetotelluric prospect results and verified by drilling. The hot water is encountered at the depth of 1290 - 1450m which is consist with geophysical prospeetion. The method could provide a reference for the future exploration of deep geothermal resources.
