Differential well temperature and pressure tester for thermal recovery horizontal well

The utility model provides a differential well temperature and pressure tester for a thermal recovery horizontal well. A first temperature measuring sensor and a second temperature measuring sensor in the differential well temperature and pressure tester for the thermal recovery horizontal well are arranged at a certain distance interval for measuring the temperature; a pressure sensor probe is used for measuring the pressure; a data acquisition circuit is positioned in a vacuum flask and is used for acquiring temperature and pressure data; the vacuum flask prevents the data acquisition circuit from being influenced by high temperature; and a protective barrel inside the tester is a protective barrel for the vacuum flask. The differential well temperature and pressure tester for the thermal recovery horizontal well solves the problems that a long horizontal section cannot uniformly absorb steam and produce fluid, a horizontal well section cannot be totally used after multi-round steam stimulation, many low-efficiency thermal recovery horizontal wells are present in the running thermal recovery horizontal well, and the like in the prior art, and has the advantages that: the differential well temperature and pressure of the horizontal well can be tested, the tester is high temperature/pressure-resistant, and a test is reliable and safe.
