The oil exploration and production (E&P) industry has made outstanding contributions to gross domestic product (GDP) growth in many countries. In recent years, the gap between energy supply and demand has widened, and, simultaneously, demand for clean energy has gradually increased. As an emerging clean energy source, shale gas has received extensive attention. However, the environmental problems caused by oil and gas extraction and production should not be underestimated. Oil-based drill cuttings (OBDC) are typical hazardous solid wastes produced during oil/gas exploration and production processes. In addition, oil-based drill cuttings ash (OBDCA) is the main product of treated OBDC and should be further utilized to avoid pollution and waste of resources. This review describes relevant policies and regulations for the OBDC. The main treatment methods for OBDC have been systematically summarized. Compared to the standard method for resource utilization of OBDCA, a novel approach was proposed to utilize OBDCA as an environment-friendly functional material for environmental remediation. The future development prospects for OBDC were envisioned to achieve sustainable development goals.
石油勘探和生产（E&P）行业为许多国家的国内生产总值（GDP）增长做出了杰出贡献。近年来，能源供需差距不断扩大，同时，对清洁能源的需求逐渐增加。作为一种新兴的清洁能源，页岩气受到了广泛关注。然而，石油和天然气开采和生产所带来的环境问题不容忽视。油基钻屑（OBDC）是石油/天然气勘探和生产过程中产生的典型危险固体废物。此外，油基钻屑灰（OBDCA）是经过处理的 OBDC 的主要产物，应该进一步加以利用，以避免污染和浪费资源。本综述介绍了 OBDC 的相关政策和法规。系统总结了 OBDC 的主要处理方法。与 OBDCA 资源利用的标准方法相比，提出了一种利用 OBDCA 作为环境修复用环保功能材料的新方法。展望了 OBDC 的未来发展前景，以实现可持续发展目标。
