description The invention provides a distributed optical fiber-based liquid production profile interpretation method and device. The distributed optical fiber-based liquid production profile interpretation method correspondingly adapted to a single-phase flow liquid production profile comprises the following steps of: generating an acoustic response reference under the condition that a liquid level in a shaft is static according to a plurality of sensors of distributed optical fibers preset in the shaft; acquiring distributed optical fiber response data of the layers corresponding to the sensors according to the sensors; and according to the acoustic response reference and the distributed optical fiber response data, respectively generating the liquid production capacity of the corresponding horizon. The method not only has the technical advantages of a distributed temperature sensing technology, but also can calculate a unique solution when the multiphase flow liquid production profile is processed and explained, so tha
