地温检测仪的研发与应用

Development and Application of The Ground Temperture Detector

该检测仪具有温度传感器的现场标定和测温结果动态数码显示两大功能,其精度在0.4℃~0.8℃范围内,额定温度范围为-55℃^+150℃,能够较准确且连续地测量钻孔内某一点水的温度。该检测仪分为缆线载体式(300m内)和钻杆载体式(2500m内)。本文介绍了该测温系统的组成、工作机理及其在桂林某地热勘探中的具体应用与分析,同时对深部温度检测提出了构想。

The author explores a portable temperature detector composed by the LM35 sensor which has two functions including field calibration and dynamic displaying for the outcome. Its accuracy is from 0. 4℃ to 0. 8℃ and rated temperature is from -55℃ to ＋ 150℃. It can exactly measure the temperature of one point continuously which is divided into cable carrier （less than 300m） and drill pipe carrier （less than 2500m）. This paper introduces the system composition, its application of the geothermic exploration in Yongfu, and meanwhile puts forward the model for deep temperature detected.
