摘要
云南昆明市海埂一地热井位于普渡河-滇池深大断裂带旁侧。该地热的形成,主要是由于丰富的大气降水通过昆明盆地边缘的断裂通道,不断向地下渗透的同时,吸收了沿深大断裂上涌的地热能量形成热水,这些热水进一步在震旦系灯影组(Z_2dn)热储层中聚集,再通过新近系(N)和第四系(Q)厚度巨大的黏性土层的封闭保护下,最终形成此地热田。
The geothermal well at Haigeng in Kunming,Yunnan is beside Puduhe-Dianchi macrofault.Because of the abundant air precipitation continuously permeating downward along the fault of Kunming basin margin and absorbing the geothermal energy rising upward along the macrofault,then the forming hot water concentrating in the Sinian Dengying Formation(Z_2dn) heat reservoir,under the close and protection of Neogene(N) and Quaternary(Q) mega-thick viscous clay,the geothermal field is formed finally.
