Currently, the alteration of external factors during crude oil extraction easily disrupts the thermodynamic equilibrium of asphaltene, resulting in the continuous flocculation and deposition of asphaltene molecules in crude oil. This accumulation within the pores of reservoir rocks obstructs the pore throat, hindering the efficient extraction of oil and gas, and consequently, affecting the recovery of oil and gas resources. Therefore, it is crucial to investigate the principles of asphaltene deposition inhibition and the synthesis of asphaltene inhibitors. In recent years, the development of nanotechnology has garnered significant attention due to its unique surface and volume effects. Nanoparticles possess a large specific surface area, high adsorption capacity, and excellent suspension and catalytic abilities, exhibiting unparalleled advantages compared with traditional organic asphaltene inhibitors, such as sodium dodecyl benzene sulfonate and salicylic acid. At present, there are three primary types of nanoparticle inhibitors: metal oxide nanoparticles, organic nanoparticles, and inorganic nonmetal nanoparticles. This paper reviews the recent advancements and application challenges of nanoparticle asphaltene deposition inhibition technology based on the mechanism of asphaltene deposition and nano-inhibitors. The aim was to provide insights for ongoing research in this field and to identify potential future research directions.
目前,原油开采过程中外在因素的改变容易破坏沥青质的热力学平衡,导致沥青质分子在原油中持续絮凝和沉积。这种在储层岩石孔隙内的堆积会堵塞孔喉,阻碍油气的高效开采,进而影响油气资源的采收率。因此,研究沥青质沉积抑制原理和合成沥青质抑制剂至关重要。近年来,纳米技术因其独特的表面和体积效应而备受关注。纳米颗粒具有大的比表面积、高吸附容量以及优异的悬浮和催化能力,与传统有机沥青质抑制剂(如十二烷基苯磺酸钠和水杨酸)相比,展现出无与伦比的优势。目前,纳米颗粒抑制剂主要有三种类型:金属氧化物纳米颗粒、有机纳米颗粒和无机非金属纳米颗粒。本文基于沥青质沉积机理和纳米抑制剂,综述了纳米颗粒抑制沥青质沉积技术的最新进展和应用挑战。目的是为该领域的 ongoing research 提供见解,并确定未来潜在的研究方向。
