涪陵页岩气田一期工程环境影响调查

Environmental Influence Investigation of First-Stage Project in Fuling Shale Gas Field

采用现场调研与实地监测相结合的方法对涪陵页岩气田一期工程污染源和区域环境质量现状进行深入调查研究,剖析涪陵页岩气开发对环境产生的影响。结果表明,涪陵页岩气田开发过程中废水实行循环利用,钻屑固体废物固化填埋,企业环保措施基本落实,短期内页岩气开发未对区域环境产生明显不良影响。指出修建井场、池体、道路等设施对生态环境具有一定影响,且随着时间推移,钻屑固化填埋对周围土壤及水环境也具有潜在影响。

In order to dissect the environmental impact of shale gas development,this paper investigated the pollution sources and regional environmental quality situations of first-stage project in Fuling shale gas field by site surveying and field monitoring methods. The results showed that the waste water was circularly utilized,the drilling cuttings were solidified and buried,and the environmental protection measures of enterprise also gradually came to be complete in the process of shale gas development. So there was no evident impact on regional environment of shale gas development in the short term. Nonetheless,in the process of shale gas development the construction of well sites,pools,roads and other engineering facilities had certain influence on the ecological environment,and the cuttings landfill also had a potential impact on the surrounding soil and water environment as time went by.
