摘要
The reservoir research and development on gas-water two phase flow are mainly concentrated on numerical reservoir simulation and mining technology. However, the gas-water two-phase flow mechanism is relatively small. The physical process is not well understood. In view of low-permeability reservoir geology of Sichuan Basin, China, fracture-pore water-wet micromodel is developed. Using the lower pressure glass micromodel, a series of gas-water two-phase flow experiments have been conducted. In this paper, results of typical water-wet tests are presented. The water flooding gas experiments in laser etching microscopic artificial physical model showed that water lock is the major features in two-phase flow in porous media.
