In the past two decades, various reservoir upscaling theories and methods have been proposed for reservoir characterization and reservoir simulation.

Aiming at the contradictions of high water cut stage oilfield, combine with fine reservoir geology, production seismology, petrophysical and geological modeling, production logging, well testing, reservoir simulation, economic evaluation and program design, the multi-disciplinary professional conduct multidisciplinary reservoir studies.

The simulation results of the simulated program were showed by data,the displacement-angle curve of the valve was drawn by the computer.

Then, the simulated program was made and the theoretical curves were drawn by the computer, through comparison of the theoretical curves with the measured ones, some suitable means on improving the efficiency of the valve are given.
