Failure rate is very high, and pressure gauge normal working hours, new technical equipment normal service life all existed not over two months according to statistics
More than 1 year.
3rd, the advantage of this equipment is in terms of comprehensive：
1) this equipment is using contactless independent measurement, and test speed is fast, and test scope is wide, to the well of underground structure complexity
It can normally measure, solve the problems, such as part well because can not measure cable under hole condition complexity；
2) well lift pipe string must be stopped relative to the maintenance of existing pressure gauge test equipment, maintenance period length it is of high cost and
The problem of influencing normal production work, the independently installed use of this equipment, maintaining do not interfere with geothermal well and normally produce；
3) to be descended to underground relative to existing pressure gauge test equipment, the longevity is used in the high temperature and pressure high mineralization liquid of underground
Life is very short, and most uses faulty will be repaired not over two months, and the long continuous work of this service life of equipment was more than 1 year
More than, because equipment does not contact high-temp liquid in well, component service life length in well head installation；
