Abstract:

Applying material balance principles, a mathematical model of multiphase flow is built to supply a tool for well test analysis of solution-gas-drive reservoirs. In the model the multiphase flow problem is described by single-phase flow equations through setting pseudo functions. A new method of calculating relative permeability and pseudo functions with production data is proposed. With the method, minimal data is needed and the calculation results are consistent. Case applications indicate that the proposed method is valid and reliable.

Key words: solution-gas-drive reservoir, well-testing analysis, multiphase flow, mathematical model
