Temperature measurements by distributed temperature sensors(DTS) are gradually being used to monitor downhole conditions of a fractured horizontal well.However,there are still great technical problems to predict the temperature profiles and diagnose the water-exit locations quantitatively of a two-phase fractured horizontal well in low-permeability gas reservoir.In this study,considering several subtle heat effects,a coupled temperature prediction model has been developed to predict the temperature profiles of a fractured horizontal well with two-phase flow in low-permeability gas reservoir.Using the developed temperature model,the temperature profiles of a fractured horizontal well with 5 different inflow-water distributions have been simulated respectively.The influences of inflow-water distribution on the wellbore temperature profiles have been analyzed as well.The predicted wellbore temperature profiles indicate that,as for a single-phase fractured horizontal well,the temperature drop at the fracture locations is positively related to the fracture half-length and the temperature characteristic value of each fracture decreases in sequence from the toe to the heel.As for a fractured horizontal well with water production,both of the temperature drop and temperature characteristic value of the particular fracture with producing water presents a phenomenon of “abnormal reduction”.Based on the aforementioned “abnormal reduction” of the temperature drop and the temperature characteristic value,two effective methods have been proposed to diagnose water-exit locations of a fractured horizontal well with known/unknown fracture half-length respectively on the basis of downhole temperature measurements.
