In the context of a low-carbon future, green, sustainable, and environmentally friendly oilfield development methods have become urgent priorities. The application of bio-based materials in water-based drilling fluids (WBDFs) and enhanced oil recovery (EOR) is emerging as a key strategy for driving sustainable development. Xanthan gum (XG), a natural polysaccharide, has gained significant attention due to its non-toxic, biodegradable, renewable, and environmentally friendly characteristics. Its shear-thinning rheological properties make it particularly suitable for oilfield development. This review summarizes the production, modification, and chemical structure of XG, focusing on key factors influencing the rheological behavior of its aqueous solutions, including shear rate, shear stress, concentration, pH, salinity, temperature, time, and polysaccharide interactions. Additionally, recent advances in XG's application in WBDFs and EOR are discussed. Although XG's viscosity stability and recovery under high-temperature and long-duration conditions present challenges, these issues have been largely addressed through increased salinity and chemical modifications. Finally, this review highlights key future research directions, such as exploring the structure-rheology relationship of XG, polysaccharide interactions, the rheological behavior and sustainability of XG derivatives, and its economic feasibility in oilfield development. These insights aim to improve XG's adaptability to harsh oilfield conditions and guide its use in similar environments.
在低碳未来的背景下，绿色、可持续和环境友好的油田开发方法已成为当务之急。生物基材料在水基钻井液（WBDF）和提高采收率（EOR）中的应用正成为推动可持续发展的关键策略。黄原胶（XG）是一种天然多糖，因其无毒、可生物降解、可再生和环境友好的特性而备受关注。其剪切变稀的流变特性使其特别适用于油田开发。本文综述了XG的生产、改性和化学结构，重点关注影响其水溶液流变行为的关键因素，包括剪切速率、剪切应力、浓度、pH值、盐度、温度、时间和多糖相互作用。此外，还讨论了XG在WBDF和EOR应用中的最新进展。尽管XG在高温和长时间条件下的粘度稳定性和恢复性存在挑战，但通过增加盐度和化学改性，这些问题已在很大程度上得到解决。最后，本文强调了未来的关键研究方向，如探索XG的结构-流变关系、多糖相互作用、XG衍生物的流变行为和可持续性及其在油田开发中的经济可行性。这些见解旨在提高XG对恶劣油田条件的适应性，并指导其在类似环境中的使用。
