摘要
粘弹性表面活性剂 (VES)基压裂液 (又称为清洁压裂液 (ClearFRAC) )的使用改变了传统聚合物压裂液对支撑剂的输送方式 ,可以消除残余聚合物对支撑剂充填层的堵塞 ,并能提高充填层的导流能力。总结和回顾了目前国内现有的压裂液体系及存在的问题 ,对国外清洁压裂液的研究状况、理论基础、研究进展及井场应用情况进行了综述。井场应用结果及与瓜胶压裂液体系组分对比表明 :清洁压裂液性能优于聚合物压裂液 ,具有高效、低伤害、配制简单的特点。
The introduction of viscoelastic surfactant (VES), or clear fracturing fluids (ClearFRAC fluid), which is capable of eliminating polymer damage while enhancing conductivity of proppant packs, has changed the way of proppant transport by traditional polymer fracturing fluids. The paper has summed up and reviewed systems of present hydraulic fracturing fluid at home and their shortcomings, and summarized the development, the theory basis and cases of successful fracturing treatments of ClearFRAC fluid in abroad. Field results have shown that the performances of the ClearFRAC fluid are better than polymer fracturing fluid, which are high effective and non-damages over conventional polymer fluid systems. Some comments on the studies of ClearFRAC fluid in our country have been given in this paper.
