In this paper,the experiments are subjected to simulate the variations of temperature and pressure in the shale sequence during the gas drilling process.We try to get the behavior of water invasion when the water flow out from the shale sequence during the gas drilling process and gas drilling adjusted to water based drilling.A correlation between water invasion distance and time is established to predict the water invasion scope and collapse range.We use this correlation to simulate two cases about water invasion distance and time,and find out that the early water invasion is fast and the late becomes slow gradually.The water invasion speed for the former case is slower than that for the latter one if the correlation between water invasion distance and time for two cases of are contrasted.The time for water invasion in the former case is 350 times than that for the latter in the 5cm water invasion distance.
