This paper introduces a new method for donwhole temperature measurement, using the optical fiber distributed temperature measurement system. This system is developed for the real time measurement of temperature field in space. In the system, the optical fiber is both transmitire medium and senditive medium. The system has better precision and space resolution, and can realize real time, multi points and fast measurement without interrupting the original distribution of the temperature field. Now this system has been applied in petroleum well logging.
