There were many times the water in 7# well in Qingshui County of Gansu Province changed to blue color. The well is located in the anomalous hot area, where deep fluid have abnormal activities. In this paper, the geological environment of the well is surveyed, the causes, storage and transport mechanism of underground gas are analyzed using physical and chemical methods. Meanwhile the causes of blue water phenomenon is explained by “The bubble migration mechanism”, it would provide an important theoretical basis for analyzing the earthquake precursor in future.
