The Three Gorges Project is famous in the world. The water head reached 135m above sea level on June 10, 2003, and the impounding water height is about 50m. The water head arrived at 156m on Oct. 27, 2006, and the total impounding water height is about 71m. In 2009, the water head will get to 175m with a total impounding water height of about 90m. The two gas wells, Luojia 16H well and Luojia 2 well, which belong to the China Oil and Gas Cooperation at Gaoqiaozheng of Kaixian county in Chongqing Municipality, triggered off two terrible gas hole blow accidents separately on Dec. 23, 2003 and on Mar. 25, 2006, and made a large loss. Apart from the factors with people’s operation, the two accidents make us think whether they are also related to geological conditions. This paper generally discusses the changing of local present hydrodynamics and geostress backgrounds caused by the Three Gorges reservoir impounding water, and suggestions are also given to prevent the third gas hole blow accident happening again.
