探析页岩气开发带来的环境影响

Analysis on the Environmental Impact of Shale Gas Development

随着油气勘探开发的不断进行,非常规油气的开发扮演者愈发重要的角色,其中页岩气的开发已成为当今能源行业一道亮丽的风景线。基于环境保护和经济发展加快了天然气的需求,随着技术的发展提升了页岩气生产的经济性,加上政府的鼓励政策和措施,我国页岩气开发的势头方兴未艾,未来页岩气市场十分广阔。水平井分段压裂技术是改善页岩气藏的重要措施更是高效开发的关键。但是在压裂的同时也带来了若干方面的问题如:水资源消耗、引发地震、温室气体逃逸、水污染等。为了环保与经济的开发页岩气,需要加强环保意识、创新绿色科技、加强环境监管的制度。绿色高效地开发页岩气具有解决我国能源短缺与环境保护相统一的现实意义。阐述了页岩气开发带来的环境影响以及提出了几点措施,期望为我国页岩气的绿色高效开发提供参考。

With the continuous exploration and development of oil and gas, the development of unconventional oil and gas plays an increasingly important role, in which the development of shale gas has become a hot spot in the energy industry. The environmental protection and economic development accelerate the demand for natural gas; with the development of technology, the economy of shale gas production is enhanced; due to government encourage policies and measures, China＇s shale gas development is fast, the future shale gas market is very broad.The horizontal well fracturing technology is an important measure to improve the shale gas reservoir and is the key to efficient development. But at the same time, there are some problems in the fracturing, such as water consumption, triggering earthquakes, escaping of greenhouse gas, water pollution and so on.For environmental protection and economic development of shale gas, we need to strengthen environmental awareness, innovate green technologies, and strengthen the system of environmental supervision. The green and efficient development of shale gas has practical significance to solve the problems of energy shortage and environmental protection in China. In this paper, the environmental impact of shale gas development was analyzed, and several measures were puts forward, which could provide some reference for green and efficient development of shale gas in China.
