清水地熱儲集層之地熱水主要來自廬山層之仁澤段破碎含水層，此地熱區破碎帶之優勢節理及活動斷層具有明顯的方向特性。因為此處基岩岩性滲透率較低所以破碎帶提供該流場流體( flow pattern )之主要通道(仁澤段岩性為板岩間夾輕度變質砂岩)，使得清水地熱儲集層地熱水之流場較接近線性流而非徑向流。本論文根據清水地熱區地質資料包括地層、構造、地熱水系統及岩石裂隙系統建立線性流場之概念模式，發現本區儲集層地下水流流場接近線性流幾何形狀，利用線性流數學模式及經常被使用到的徑向流數學模式分析清水地熱區現場干擾試驗數據後，發現線性流流場數學模式較徑向流流場數學模式更適合應用在清水地熱區干擾試驗分析。

Thermal water production in Chingshui geothermal reservoir is largely from the fracture zone in the Jentse member of Lushan Formation, which is evidently controlled by the predominant joints and active faults. Because the rock matrix has very low permeability, the fracture system provides the main conduit for fluid flow. Linear flow appears to be a more likely configuration than radial flow. A conceptual linear flow model was developed based on geological data of Chingshui geothermal area. Field data of interference test in Chingshui geothermal field appears to be rare in the literature. Both a radial flow model and a linear flow model were used to analyze an interference test in Chingshui geothermal reservoir to determine values of reservoir transmissivity. The analyses of reservoir transmissivity and well productivity revealed that a linear flow model was significantly better than a radial flow model for interference analysis in Chingshui geothermal field.
