摘要:

近年來，油田采油過程對驅油材料的性能提出了更高的要求，使用納米材料是從微觀角度提升驅油劑性能的重要方法。研究表明，對納米材料進行改性處理，如表面接枝改性、構造核-殼分子結構等，以及將納米材料與其他驅油材料（如聚合物、表面活性劑等）復配，可從降低油水界面張力、乳化原油降低原油粘度、改善巖石表面潤濕性、穩定泡沫等方面推動原油流動，可見納米材料在提高原油采收率方面具有重要意義。綜述了近幾年國內外納米SiO2、納米TiO2、納米纖維素、聚合物納米微球、納米石墨烯等納米材料在驅油材料中應用的研究進展，解析了其研發中的瓶頸問題及今后的研發方向，評述了各種納米材料提高原油采收率、抗溫、抗鹽等性能，以期為相關研究提供借鑒。

Abstract:

In the oil production process, higher requirements have been put forward by the oilfields for the performance of oil-displacing materials in recent years. The application of nano-materials is an important method to improve the performance of oil-displacing agents from a microscopic point of view. Current research shows that the modification of nanomaterials, such as surface graft modification, core-shell molecular structure construction, and the combination of nanomaterials with other oil displacement materials such as polymers and surfactants can improve the crude oil recovery. Nanomaterials can promote crude oil flow by reducing oil-water interface tension, emulsifying crude oil to reduce the viscosity of crude oil, improving rock surface wettability, and stabilizing foam. It can be seen that nanomaterials are of great significance in the enhancement of oil recovery. The research progresses of nano-SiO2, nano-TiO2, nano-cellulose, polymer nano-spheres and nano-graphene at home and abroad in recent years are all reviewed. The bottlenecks in the research and development are analyzed and the future research and development directions are proposed. The properties of nanomaterials, such as improving oil recovery performance, temperature resistance, salt resistance, etc., are reviewed in order to provide reference for related research.
