Oil And Gas Reservoir Multiphase Flow Dst Test Theory Methods

This paper taking individual well as its main object of research, makes a systematic study of the fundamental theory for multiphase flow through porous media.It has obtained the flowing achievements.â–  By doing research on the foundmental theory of flow through porous media, it simplify the mathematics model. After getting simple analytical solution, It draw Semilog plot and obtain lots of parameters, based on which we ought to select different pressure and matter parameters in different liquid quality and test condition.â–  Compare pressure approach with pressure-squared approach. Pressure approach is suite for low rate in water-oil system. Pressure-squared approach is suite for high rate in gas-oil system.â–  This paper studies relative permeability curve and PVT properties in individual well and introduce pseudopressure function into multiphase well test so that we can explain multiphase well test like single phase.â–  This paper devied the water saturation partial differential equation and pressure distribution partial differential equation. By solving them, it obtains parametesr.â–  This paper studies pressure drop and build up in flowing well, including conventional and modern analysis method.â–  Based on the above-stated transient flow the theories and well test analysis methods, this paper develops software. The software instruct manufacture and acquire well effect of society and economy.
