川南地区页岩气开发过程中重点环境影响及污染防治建议

Key Environmental Impacts and Pollution Control Suggestions during Shale Gas Development in Southern Sichuan

摘要: 页岩气是一种重要的非常规天然气资源，已成为油气资源领域重要的组成部分，川南是中国石油页岩气勘探开发的主战场，目前，川南已成为我国最大的页岩气生产基地。页岩气在开采的过程中所造成的环境问题日益突出，主要表现在钻井过程中噪声对附近居民的影响、水基钻井固废和油基钻井固废处置压力大、压裂返排液处理困难。针对川南页岩气开发生产与环境保护的矛盾，分别从噪声、固废和废水三方面提出页岩气开发过程中的污染防治建议。

Abstract: Shale gas is an important unconventional natural gas resource, which has become an important part of the field of oil and gas resources. Southern Sichuan is the main battlefield of oil shale gas exploration and development in China. At present, Southern Sichuan has become the largest shale gas production base in China. The environmental problems caused by shale gas exploitation are increasingly prominent, which are mainly reflected in the impact of the noise on nearby residents, the high pressure of water-based drilling solid waste and oil-based drilling solid waste disposal, and the difficulty of fracturing flow back fluid treatment. In view of the contradiction between shale gas development and production and environmental protection in Southern Sichuan, this paper puts forward suggestions on pollution control in the process of shale gas development from three aspects of noise, solid waste and waste water.
