These enhance national energy security and are among the cleanest, ecologically safest coal utilization technologies. This paper delineates the major characteristics of such technologies and analyzes technical solutions. Highlighting the desire to develop large scale industrial UCG plants, pilot level projects are presented using a new UCG method developed in Russia by Joint Stock Company Gazprom Promgaz. This method is distinct for its high controllability, stability, and energy efficiency. New, efficient technical solutions have been developed over the last 10-15 years and are patented in Russia. They guarantee controllability and stability of UCG gas produc- tion. Over one hundred iniection and gas production wells have been operated simultaneously.展开更多

China＇s demand for energy rises steadily with its fast econornic growth. In face of energy resources shortages. China has to implement a twofold strategy on the energy issue： strenuously consolidating domestic resources construction, and rigorously enforcing energy-saving by improving public awareness of energy conservation.展开更多

After reviewing the achievements and summarizing the problems of the oil and gas industry in China, this paper lays emphasis on the key aspects of this new round of deepening reforms, and holds rite position that this reform, based on the implementation of the national energy strategy, covers the entire oil and gas industry chain by liberalizing market access, reforming market mechanisms, and strengthening management. The reform will bring far-reaching effects upon the entire chain and the participants of the oil and gas industry. It will help to improve the market-oriented allocation of resources, allow enterprises to interact as competitors, and enhance the national oil and gas security.展开更多
With the development of Chinese economy at high speed continuously for a decade,the oil consumption has entered into a fast increasing phase that with yearly average increase rate of 7.1%.

Xinjiang with abundant resource will have played as a strategic succeeding area. While the output of the eastern oilfields decreasing year by year and imported oil dependency rising up to 45% in China. Xinjiang has become the focus concerned by the government and the petroleum enterprises.展开更多

The verified data show that the modified model is more accurate in the urban area of Shijiazhuang. Using the modified model predictions, the control strategies of sulfur dioxide in the urban area have been studied, and the result show that the second long-term (to 2010) strategy can mitigate air pollution significantly and maintain pollution levels within permissible limits.展开更多

GHG emissions mitigation for the global climate changes has been the focus of concern of the world. As the biggest developing country and the second largest country of carbon-emission, China attaches importance to the carbon emission reduction. The major GHG component is carbon dioxide and in China, the emis- sion of carbon dioxide is mainly from industrial production. In the paper, the status and trend of Coz emission from industrial departments, high-carbon emission and its specific industries are shown in statistics. Meanwhile, the policy environment, industrial organization structure and technology of carbon high emission are all discussed based on practical situations in these departments and industries. At the end, through the analysis of gray correlation, correlativity is explored for both fossil energy consumption and total carbon emission, and also for the production value and carbon emission of each industrial sector. Some policy proposals for the establishment of low-carbon industries and transition of economic development pattern are set forth.展开更多
