| Abstract: | If fluid flowing pressure is smaller than bubble point pressure, downhole fluids flow in a flowing regime of oil/gas/water phase In view of the problem of three phase flow interpretation, a method for applying grey theory and optimization technique to processing three phase producing profile is presented This method sets up the minimal target function and ideal response equations of apparent fluid velocity (flow rate), density, holdup, temperature and pressure on the basis of slip models It uses grey model GM(1,1) in predicting some parameters based on the recent dynamic data before interpreting data The predicted results are taked as primary values and used in optimization model to get the optimum results |
