ABSTRACT:
A kind of underground temperature and pressure measuring system for hot-exploiting oil well mainly comprises a casing, a high-temperature sealing element, a high-temperature time-controlling unit, a pressure sensing unit and its recording system and a temperature sensing unit and its recording system, wherein, the high-temperature sealing element is made of flexible graphite, and the pressure sensing element is made of particular material; the temperature sensing unit is connected with the pressure sensing unit by bellows, so that the temperature sensing unit and its recording system can be put around the pressure sensing unit and its recording system, and therefore the present device is not long, but it can be used to measure temperature and pressure of underground steam at different depth simultaneously, which make the calculation of underground thermal conditions possible and reliable.
