In Fuling shale gas field, multistage fracturing and staged perforation are often used to complete well. The production of each section is needed to know urgently by Gas reservoir development and management. The output profile test is the most direct method to obtain the output of each section. For the horizontal well with stable production, the horizontal section can be divided into the pipe flow section between two perforation clusters and the perforation section at the perforation cluster position. The energy conservation equations of pipe flow and inflow fluid in perforating cluster are applied to pipe flow sections and perforation sections respectively in the whole well. Then the interpretation model of the whole well output sections is established. The temperature, pressure, well trajectory and other data were measured along the horizontal section of a shale gas well. And the corresponding geological parameters were selected. The interpretation model of the whole well production profile was applied, and the model equations were solved by calling the lsqnonlin function of MATLAB. The example calculation results show that the model can meet the requirements of engineering application. It is concluded that the quantitative calculation of horizontal well production profile can be realized by using temperature and pressure test.
