Methods According to the geologic structure and perforation production well section of Du 66 steamflooding reservoirs, high temperature and high pressure thermocouple beams and direct reading instruments were designed, and the temperature of each oil layer was monitored while downhole. Objective To solve the problem of reservoir dynamic monitoring in steam flooding process. Results The technique was field-tested in Well Guan 6 after it was tested on the ground. The monitoring results are consistent with those calculated from wellbore models and production parameters. Conclusion The monitoring technology of temperature profile of steam flooding reservoir solves the problem of reservoir dynamic monitoring during steam flooding. The thermocouple beam technology can realize continuous and continuous monitoring of all oil reservoirs and cooperate with ground system to realize the direct reading of reservoir temperature and automatic Record reservoir temperature profile.
