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 carbonatite sediment in the South China have the favorable conditions for shale gas accumulation and are very promising for exploration, so they are the important areas deserving people's concern. Many seismic data analyzed, Bottom Similating Reflectors (BSR) have been found in the slop of Okinawa trough, northern slop of the South Sea, trough of the South China Sea, south slop of Hsisha Islands etc. the sedimentary samples of natural gas hydrate were acquired at the bottom of Shenhu area in South China Sea. The geological conditions of unconventional gas are complex and different. Some technologies are juvenility and cannot fit for exploration & development. The output of a single well is low in permeable reservoir. So many theory and technology problems need to be solved, restricting the development step of unconventional gas in China. According to the major issues existing in unconventional gas studying, the major technology needs in the course of exploration and development are the five aspects: strengthening the basic research and developping different types technology of tight gas; optimizing CBM favorable target and expanding the scale of CBM exploration and development; effective technology of high step coal reservoir's exploration and development; investigating the distribution of shale gas resources and finding out the major accumulating factors; carrying out the resources assessment of gas hydrate resources CONGTP 175457 175457 0 0 0 0 243276 BAAB BAAB 2026-03-05 200047347 0 200047347 2026-03-05 18:54:47 2026-03-05 CONGTP
