非常规油气开发节水压裂液技术及返排液处理

Water-saving Fracturing Fluid Technology and Flowback Fluid Treatment for Unconventional Oil and Gas Development

非常规油气的大力开发带来了新的环保问题,其中最显著的就是水资源消耗和返排液带来的水污染问题。详细介绍了国内非常规油气开发过程中节水压裂液技术和压裂返排液处理技术的研究进展,认为非常规油气开发无水/少水压裂液等节水压裂液技术仍处于研究阶段,尚未进行大规模应用。应规范非常规油气开发操作程序,促进压裂返排液回用处理装置模块化和标准化,对不同地区非常规油气开发适配的压裂液及压裂返排液回用技术进行筛选研究并形成技术体系的建议,以保证非常规油气的绿色可持续发展。

The vigorous development of unconventional oil and gas has brought new environmental problems,the most notable of which is the water pollution caused by water resource consumption and flowback fluid.This paper introduced the domestic research progress of water-saving fracturing fluid technology and fracturing flowback fluid treatment technology of unconventional oil and gas development in China in detail.It is considered that water-saving fracturing fluid technology such as anhydrous/less water fracturing fluids for unconventional oil and gas development are still in the research stage and have not been applied on a large scale;in order to ensure the green and sustainable development of unconventional oil and gas.It is needed to standardize unconventional oil and gas development operation procedures,promote the modularization and standardization of fracturing flowback fluid reuse treatment device,and screen suitable fracturing fluid and fracturing flowback fluid reuse technology for unconventional oil and gas development in different areas to form the technical system.
