The absence of horizontal well temperature profile prediction models and the unclear dominant factors affecting the temperature profile make it very difficult to invert and interpret the production profile of fractured horizontal well in tight gas reservoirs based on the temperature test data of distributed optical fiber. To this end, a coupled temperature profile prediction model was established for fractured horizontal wells in tight gas reservoirs, taking into account multiple micro thermal effects and heat transfer in the fracture system, the reservoir temperature distribution and wellbore temperature profile characteristics of fractured horizontal wells in tight gas reservoir were simulated and analyzed, and the influence of different influencing factors on temperature profile was evaluated by orthogonal experimental analysis and quantitative empirical analysis. It was found in the study that the following factors were listed in descending order according to their influence of the factors on the temperature profile of fractured horizontal wells in tight gas reservoirs: fracture half-length, daily gas production of single well, reservoir permeability, wellbore diameter, fracture conductivity, wellbore inclination in horizontal section and the total thermal conductivity of the reservoir; the dominant factors were fracture half-length, daily gas production of single well, and reservoir permeability. The establishment of the temperature model and the determination of the dominant factors of the temperature profile laid a theoretical foundation for the quantitative interpretation of the production profile and fracture parameters of the fractured horizontal wells in tight gas reservoirs.
