| Popis: | The reform and new policies of national oil and gas mining rights system have led to the increasing number of mining rights blank areas. In order to tap and enhance the strategic value of oil and gas in blank areas, promote the discovery and full use of oil and gas resources, and ensure the national energy security, this paper, by analyzing the structure and distribution characteristics of China's oil and gas resources, focusing on the main mining rights blank areas on land, and studying on oil and gas geological conditions and key reservoir-forming factors, carries out the optimization of strategic area selection and key exploration fields according to the process of stepwise classification. It is pointed out that the natural gas in the deep depression of the north and south platform basins of the Tarim Basin, the Carboniferous natural gas and the Jurassic coalbed gas in the northeast of the Junggar Basin, the Neopaleozoic tight gas and coalbed gas in the eastern and northern margins of the Ordos Basin, and the marine shale gas in the extrabasinal gentle structural area of the Middle and Upper Yangtze are the key directions for future strategic area selection. Combined with the characteristics and key problems of oil and gas geology in various fields, suggestions are put forward for deepening research, technical research direction and evaluation of selected areas. |
