Application of Outside Casing Water Level Monitoring Tube System in Medium-low Temperature Geothermal Well

摘要

It realized the geothermal well water level dynamic monitoring by installing a set of water level monitoring tube system outside casing. Based on this achievement, the author carried on reduced pressure test and monitored data of water level in the conditions of outside casing and inside casing. According to the comparison results, the actual error value was between 0 m and 0.02 m, in the range of allowable error, which do demonstrate the water level monitoring tube system outside casing can be competent for observingthe geothermal well water level.
