Development and application of storage high temperature and high pressure borehole thermometer
Abstract:In order to solve the problem of temperature measurement at high temperature above 200℃ and provide technical support for high-temperature geothermal and dry hot rock exploration, a storage high temperature and high pressure borehole thermometer was developed by using platinum resistance temperature measurement technology and vacuum insulation technology. The instrument is designed for working environment temperature of 300 ℃ and water pressure resistance of 100 MPa. It can be used for borehole temperature measurement in high temperature and high pressure. The instrument has been used in huire-1 well and GH-01 well,It can meet the borehole temperature measurement requirements.
