The Block Optimizing Selection and Eco-Environmental Problems of China Shale Gas Exploration and Development

Abstract:

China mainland shale gas exploration and development are carrying out gradually. According to shale gas enrichment degree, water resources distribution and the practice of exploration and development, China mainland shale gas resources can be divided into five blocks. On this basis, the author preliminary discussed the distribution of water resources and eco-environmental problems during shale gas exploration and development. Considering the practice of shale gas exploration and development and water resources situation, the author put forward that the Upper Yangtze and Yunnan-Guizhou-Guangxi region would be the most favourable block, and there are problems with China mainland shale gas exploration and development, such as large water consumption, well drilling water leakage and mud loss which would contaminate groundwater. In addition, shale gas well injection (grouting) might cause the occurrence of seismic events. After analyzing the two different kinds of opinions on whether China mainland shale gas exploration and development would cause environmental problems, the author pointed out that, without a doubt, there exist eco-environmental problems during shale gas exploration and development, and further proposed that we should put the environmental protection at first place and take the road of environment-friendly shale gas exploration and development by reference to the exploration and practice of shale gas development both of China and other advanced countries in the world.
