Heat transfer process of gas lift annulus hot injection wellbore is very complex. Established is a new wellbore heat transfer model based on previous research results and comprehensively considering gas lift annulus hot injection wellbore heat transfer process, and obtained is a new temperature prediction model through correction of previous temperature prediction model. Applied is field test data fitting to obtain equivalent radius of annulus heat transfer in the new wellbore heat transfer model and determine necessary parameters in new temperature prediction model. Conducted is verification on the new model in several field cases and it is proved from such issues as the accuracy of the prediction and hot gas influence depth that the new model is reliable.
