页岩气开采中压裂废液处理技术的发展及应用

作为新型的天然气资源,近年来页岩气的开采力度不断增加。文章广泛调研页岩气开采过程中的场地修复、压裂废液处理等方面的环境污染风险,国内外现行压裂废液的处理工艺,系统分析了中和法、絮凝法和氧化法等处理工艺,并结合实际应用效果和企业需求对技术发展方向进行了预测,可为非常规油气资源开发领域提供理论参考。

Development and Application of the Treatment Technology of Fracturing Liquid Waste in Shale Gas Development

As the new resource of natural gases,the development of shale gas is increasingly enforced in recent years.This article widely conducts research for the environmental contaminating risks of site remediation,fracturing liquid waste management and other respects in the developing course of shale gas,and for the fracturing liquid waste management technology in force domestic and abroad.It also analyzes the management technologies including neutralization method,flocculence method,and oxygenization method.Technology tendency is also predicted in line with actual applying effect and industrial needs,which provides theoretical reference for the unconventional oil and gas resource development.
