Abstract

A variety of chemicals are used in various stages of oil exploitation to ensure the normal progress of exploitation and improve the efficiency of oil recovery. However, most of the conventional petroleum-based chemicals are non-biodegradable, which will remain as wastes after applying, leading to serious environmental menace. In recent years, cellulose nanomaterials have attracted extensive interest due to their renewable and biodegradable features, as well as excellent chemical, mechanical, and rheological properties. This review comprehensively summarizes recent advances in exploring cellulose nanomaterials for oil exploration applications. Firstly, the preparation and properties of cellulose nanomaterials are briefly introduced. Then, the applications of cellulose nanomaterials in different petroleum exploitation processes, including drilling, cementing, and enhancing oil recovery are systematically discussed. Finally, the perspectives and challenges of cellulose nanomaterials for oil exploration applications are provided. It is expected that cellulose nanomaterials will be developed as promising oilfield chemicals for large scale application.

摘要

在石油开采的各个阶段使用多种化学品，以保证开采的正常进行，提高采油效率。然而，大多数传统的石油基化学品是不可生物降解的，使用后将作为废物残留，导致严重的环境威胁。近年来，纤维素纳米材料因其可再生、可生物降解的特性以及优异的化学、机械和流变性能而引起了广泛的关注。本综述全面总结了探索用于石油勘探应用的纤维素纳米材料的最新进展。首先简要介绍了纤维素纳米材料的制备和性能。然后，纤维素纳米材料在不同石油开采过程中的应用，包括钻井，系统地讨论了固井和提高采收率。最后，提供了纤维素纳米材料在石油勘探应用中的前景和挑战。预计纤维素纳米材料将被开发为有前景的大规模应用油田化学品。
