推測地熱井之原始溫度為地熱開發過程中之重要工作之一。原始測度可應用Horner之方法推測之,唯傳統的原始溫度之推算及其校正之方法仍採用作圖法,因地熱井測點甚多,如採用作圖法,不但推算作業非常費時,而且容易發生誤差。本文旨在研究推導原始溫度及校正原始溫度之數學程式,以應用磁卡電子計算機在地熱井現場計算原始溫度,俾提高推算之精確度,並節省時間與人力。
When drilling a geothermal well, it is important to know the static formation temperature prior to setting casing pipe, The static temperature can be estimated by plotting the pertiment data on the semi-long paper. It is often a tiresome and easy-erroneous work for engineers. In order to save rig cost, the author have derived equations for using a programmable hand computer at the drilling site to calculate the static temperature quickly and precisely.
