During the process of oil extraction, oil pressure and temperature data always play an important role in dynamic monitoring of reservoir development. By mastering temperature and pressure changes, the degree of reservoir utilization, productivity, dynamic fluid capacity, and reservoir edge exploration can be analyzed. Understanding the vertical temperature and pressure distribution of the oil reservoir is crucial for developing development plans, improving reservoir utilization and recovery rates.

The application of distributed fiber optic temperature measurement system can achieve accurate measurement of temperature distribution throughout the well without affecting the original temperature field, pressure field, and normal production of the oil field.
