DEVELOPMENT TREND OF UNCONVENTIONAL GAS RESOURCES IN CHINA Hongyan Wang, Guangjun Wang, Honglin Liu, Qun Zhao, Dexun Liu Langfang Branch Institute of the Research Institute of Petroleum Exploration and Development, Langfang 065007, China Abstract Many countries in the world begin to attach great importance to the utilization of the unconventional gas. In some areas, tight gas, Coalbed methane (CBM) and shale gas have came into commercial development. The unconventional gas resources are very abundant in China. They developed rapidly in recent years, and some progress has been made. CBM in Qinshui Basin has been commercially developed successfully. Shale gas resource is also very abundant and has a good development prospect. Besides, the gas hydrate has a great potential in resources. With scientific technologies advancing, many key technology handicaps will be overcome continuously. Reasonable and effective utilization of the unconventional gas can ensure the sustaining development of Chinese economy. There is estimated more than 12 trillion cubic meters, which takes 20 percent of the total production of the natural gas. The exploration and development of tight gas is mainly in the upper paleozoic gas reservoir, Xujiahe reservoir in Sichuan and jurassic-cretaceous reservoir in Kuche. Some progress has been made in CBM exploration and development in China and some mature technology series were established. Qinshui Basin is the main CBM development field in China. It is estimated that the rate is up to nearly 600 billion cubic meters per year. The industry scale has formed primarily. In the end of 11th Five-year (2010), 3 billion’s productivity is programmed to be built. Shale gas industry in china has just come into forth, and resources evaluation and exploration work has not opened out yet. The Sichan, Tarim, Ordos, Tuha, Songliao basins and the areas with carbon
