Abstract: Gas-water two-phase percolation in water-drive reservoirs belongs to multi-phase flow, the flow exists in middle-late stage of developing water-drive gas reservoirs. Theories of numerical simulation and well test analysis are built up using mechanics of flow through porous media, and which are the practical applications. First, this paper comments on advances of experimental
mechanics of water-drive gas reservoirs, then, analyzes application of gas-water two-phase percolation in numerical simulation and well test analysis, at last, prospect present research content for gas-water two-phase percolation, also, the basis for studying theory and application of gas-water two-phase percolation is provide by the paper.

Key words: gas-water percolation, experiment, numerical simulation, well test
