Abstract]In 2007, the "Gas Pipeline from Sichuan to China Eastern Region"  Project was officially taken into operation. This project is a great program of the national "11th Five-Year Plan"  and has great significance for promoting the energy structure adjustment and for improving the ecological environment of the six provinces and two cities along the line. Three years later, the exploration and development progresses have shown that the Puguang Gas Field, the gas resource base of the "Gas Pipeline from Sichuan to China Eastern Region"  Project, is a large scale gas field with high quality and yield. In addition, gas reserves of the Yuanba Field and the Tongnanba Field are growing. Great potential of exploration has also been shown in the Nanjiang and the Zhenba area. Consequently, resource basis with growing reserves of the project is reliant, which assures the broad prospect of the project.
