非常规压裂液体系研究进展

Research progress in unconventional fracturing fluids

在研究大量文献的基础上,对新型压裂液的发展现状做了综述。根据化学组成成分的不同,将新型压裂液分为黏弹性表面活性剂压裂液、聚合物压裂液、泡沫压裂液、干法CO_2压裂液、其他新型压裂液。总结了不同种类的压裂液特征、存在的问题和适用的油藏环境,以期对压裂液的研究提供相关的借鉴。

Based on the study of literature,research progress of fracturing fluid is summarized. The fracturing fluid types are classified into viscoelastic surfactant fracturing fluid,polymer fracturing fluid,foam fracturing fluid,dry CO_2 fracturing fluid and some new fracturing fluids. For all types of fracturing fluid,their characteristics,disadvantages and match ability are analyzed and discussed to provide references for further studies.
