油气田废水地下灌注技术及其环境风险分析

Underground injection technology and environmental risk analysis of oil–gas field wastewater

国家对环境保护与环境污染治理重视程度不断增加,解决油气田废水的出路与气田开发息息相关,一些常规油气田废水处置方式已经不能满足可持续发展的要求。为此研究了深部地下灌注技术在油气田废水处置中的运用,并结合国内油气田废水特征总结出一套地下灌注技术方案,最后针对此技术在实际运用过程中的环境风险进行了简要分析评价,并提出了相应的防治措施。

Along with increased attention of environmental protection and pollution treatment,some regular wastewater disposal ways for oil-gas fields cannot meet the requirement of sustainable development.Meanwhile,how to dispose wastewater has close rela-tion to the oil-gas field development.The effect of deep underground injection technology for oil-gas field wastewater treatment is intro-duced in this paper.In consideration of the characteristics of domestic oil-gas field wastewater,one solution for underground injection technology is summarized.Finally,the potential environmental risk in practical application is briefly analyzed and assessed,and some corresponding preventive measures are put forward.
