摘　　要：利用羊易地热田一些热泉和钻孔的地表面分布模式、蚀变矿物类型 ,来追索热流体的主要通道 ,判断热田边界以及地层渗透性能 ,根据在石英、方解石和萤石中测量的 1 1 6个汽液包裹体的均一化温度 ,可以推测热储的温度变化趋势 。Through the distribution pattern of surface manifestationa and alteration minerals from some springs and drillholes in Yangyi geothermal field,it is expected to find the main channel of geothermal fluid,range of geothermal field,as well as permeability of stratum.Homogenization temperature of 116 fluid inclusions in quartz,caldite and fluorite suggests that the trend of temperature be changed.It supplies a effective foundation for developing and using hydrothermal resource.
