水基压裂液增稠剂研究进展

Research on the Progress of Water-Based Fracturing Fluid Thickening Agent

增稠剂是水基压裂液的主要添加剂之一,其优异的性能在很大程度上决定了压裂液的性能,而增稠剂大致分为天然植物及其改性增稠剂和高分子增稠剂,前者对自然环境的危害较小,后者可用于不同地质条件下压裂液的现场混配。重点介绍了天然植物改性增稠剂、微生物多糖和聚合物增稠剂的性能,并对各类增稠剂进行了综述,为该领域的后续研究提供理论依据。

Thickener is one of the main additives of water-based fracturing fluid,and its excellent performance largely determines the performance of the fracturing fluid,while thickeners are broadly divided into natural plants and their modified thickeners,which are less harmful to the natural environment,and polymeric thickeners,which can be used for on-site mixing of fracturing fluid for different geological conditions.This paper focuses on the performance of natural plant modified thickeners,microbial polysaccharides,and polymeric thickeners,and provides a review of the various types of thickeners to provide a theoretical basis for subsequent research in this area.
