Abstract

The tight sand gas is becoming one of the most important domains in unconventional natural gas exploration & development in the world. Especially the large-scale exploration and utilization of American tight sandstone gas promotes the exploration & development in other countries.Based on a brief overview of global tight sandstone gas exploration & development,the paper carries out a systematic study on the exploration history, the exploration effect as well as the development tendency and proposals of China's tight sandstone gas. The result shows that the development process of China's tight gas development can be divided into three stages and is entering the fast-developing stage recently.In recent years, several large tight sandstone gas reservoirs are discovered in upper Palaeozoic of Ordos Basin, Xujiahe Formation of Sichuan Basin and deep formations of Kuqa, Tarim Basin. The reserve and production of tight sand gas have both experienced rapid growth. The production accounts for 1/5 of China's total nature gas production in 2011, and it is predicted to reach 1/3 in 2020, and at that time the tight sandstone gas would become the key role in natural gas industry.
