摘要
断裂裂隙型地热田热储为断层破碎带和裂隙发育带,呈脉状或带状,受断裂构造控制,其各向异性特征明显,地热流体的分布严格受断裂构造控制。作者以英山西北汤河热田区为例,阐述了该断裂裂隙型地热田的地温度场特征,指出了采用"横向地热梯度最大值"、"横向地热梯度0值"、"垂向地热梯度值"、不同高程温度等值线和"垂向地热梯度场形态"如凹型或凸型等定量和定性指标来表述断裂裂隙型地热田的地温度场特征,论述了其地热地质意义和与主要导热导水构造的关系,并应用其相关指标来确定主要导热导水构造。
In veinal or zonal distribution,the geothermal reservoir of fracture-type occurs in the faulted fracture zone and developed fracture zone.Controlled by faulted structure,this type of geothermal field is characterized by primary heating model with deep cyclic geothermal temperature-rising and distinct anisotropy that shows the differences of the geothermal reservoir parameters.The distributed coverage of the geothermal fluid is controlled by faulted structural systems.Taking Yingshan Tanghe geothermal fields...
