| Abstract: | This paper studies the law of water invasion in the clay shale formation with mathematical model and simulation when gas drilling is changed to water-based drilling.The mathematical model makes it possible to obtain the distribution of water saturation and the distribution of water and gas pressure.According to the distribution of water saturation,it is possible to calculate the distance of water invasion,and predict the range of water invasion.At the same time,we have developed the experimental research wi... |
| Keywords: | shale water-gas two-phase flow gas drilling the range of water invasion |
