Graphene is a material formed with carbon atoms connected by sp hybridization. It is extremely strong and very ductile, and is superhydrophobic and superlipophilic. It has important application prospects in materials science, micro and nano processing, energy, aerospace and biomedicine. Graphene also has some applications in the petroleum industry. As nanoscale materials, graphene-based materials can plug nano-pores and prevent water intrusion into clay minerals during the drilling process, they are suitable for sliding between layers and can be used as lubricants due to the two-dimensional structure. The adsorption properties of graphene-based materials allow them to improve the treatment rate when treating oily wastewater. This paper compiles recent advances in the application of graphene and its derivatives in oilfield extraction, including improving drilling fluid performance, enhanced oil recovery and oily wastewater treatment. We compare the performance advantages of graphene-based materials over other additives, and summarize the mechanism of action of graphene-based materials. The shortcomings of current research are identified and future research and improvement directions are envisaged.
石墨烯是一种由通过sp杂化连接的碳原子形成的材料。它极其坚固且非常有延展性，具有超疏水性和超亲油性。它在材料科学、微纳加工、能源、航空航天和生物医学等领域具有重要的应用前景。石墨烯在石油工业中也有一些应用。作为纳米级材料，基于石墨烯的材料可以堵塞纳米孔隙并在钻井过程中防止水侵入粘土矿物，由于其二维结构，它们适合层间滑动并可用作润滑剂。基于石墨烯的材料的吸附特性使其在处理含油废水时能够提高处理率。本文汇编了石墨烯及其衍生物在油田开采中的应用的最新进展，包括改善钻井液性能、提高原油采收率和处理含油废水。我们比较了基于石墨烯的材料相对于其他添加剂的性能优势，并总结了基于石墨烯的材料的作用机理。识别了当前研究的不足，并设想了未来的研究和改进方向。
