Analysis of High Temperature Monitoring Well in Taitung Jinlun, Taiwan

Abstract

Taitung Jinlun Hot Spring Area in Taiwan is rich in hot spring resources and vast hinterland. After the hot spring area is completed, the application for hot spring development and geothermal power generation continues to increase. Under the premise of ensuring the sustainable use and operation of the hot spring industry, it is necessary to establish a hot spring monitoring well to monitor the impact of development activities on hot spring resources, and to protect the hot spring resources. The monitoring well was set on the left bank of Jinlun red bridge. The monitoring well depth is 94 meters, which is high temperature, high pressure and self-injection well. The hot spring pH is 8.7 and water temperature is 72.1 degrees. The water quality is sodium bicarbonate and outflow is 0.00146 cms. The water discharge test by the Jinlun Hot Spring monitoring well shows that the water level in the well is between 54.4 and 58.1 meters in elevation when the wellhead valve is closed. Monitoring the opening of the well valve, the pressure is released due to the hot spring water, and the water level is reduced from 58.1 meters to 43.75 meters. Therefore, the monitoring of the hot spring water in the well can be ejected from the surface of the ground at a height of 14.35 meters.
