页岩气返排液处理现状

页岩气作为一种清洁、低碳、高储量的非常规天然气,已成为未来天然气资源的新宠儿。但是目前其开发方式是水力压裂,该法在开发过程中会产生组分复杂的压裂液返排液。针对制约页岩气勘探开发的压裂返排液处理技术,系统梳理了国内外真对压裂返排液组成及处理技术的现状并通过与美国等发达国家技术的对比对我国未来页岩气发展进行了展望。

Present Situation of the Treatment of Shale Gas Fracturing Flowback Fluid

Shale gas as a clean and low carbon unconventional natural gas with high reserve has become a new darling of natural gas resources. But at present, its development mode is hydraulic fracturing, which can produce complex fracturing fluid in the process of development. In this paper, composition and treatment technologies of shale gas fracturing flowback fluid at home and abroad were discussed, and domestic treatment technology was compared with those of the United States and other developed countries. At last, future development trend of shale gas in China was prospected.
