U.S. shale gas development environmental problems encountered in our country are also likely to occur


China's development of shale gas technologies may require from the United States, the U.S. experiencing environmental problems in our country are also likely to occur. In addition, China's  shale gas  resource-rich regions are mainly Basin, eastern Chongqing in western Hubei, Guizhou and Hunan area, Ordos Basin, Tarim Basin and other remote areas. This particular geographic distribution of shale gas development has also led to environmental problems, compared with the United States there may be more tricky place. In summary, our shale gas development environment issues will be mainly in water consumption and pollution, mining places of geographical and environmental conditions as well as the lack of environmental laws and regulations, etc.,Fracturing proppant copy successful U.S. shale gas will be difficult. It should be said that China shale gas, the most worrying is that we may be faced with a serious shortage of water resources in a critical situation. Of shale gas fields are mostly located in areas of serious water shortage. Water is relatively abundant in the Yangtze River basin, Jianghan Basin in Sichuan and only discovered shale gas; while in the northwest, north China, shale gas reserves are abundant, local water resources is quite tense. Coupled with drought in southwest China in recent years, frequent, large-scale development of shale gas may make the local water shortage situation worse. From the geographical point of view, China's shale gas resources are located, may not be suitable for large-scale exploitation of shale gas. Requires a lot of shale gas drilling, is probably 10 times the conventional gas reservoir, drilling and production operations on the ground greater impact. U.S. shale gas distribution area surface in excellent condition, flat, sparsely populated, and the distribution of high-quality shale are concentrated in the central and western mountainous areas, surface topography, terrain elevation large, dense population distribution, shale gas is also buried deeper than the United States. Therefore, these areas may not be suitable for large-scale exploitation of shale gas, otherwise it will affect the normal life of residents, increasing demands on local infrastructure, poor economy, but also easily lead to landslides and other geological disasters. Therefore,frac sand companies many of the benefits of shale gas development, risk does not seem small. Huge economic benefits of shale gas makes the initial development we need, to start thinking about their development-related issues, to avoid repeating other resource-based products under development lessons.
