Abstract

Considering the lifespan of wells and the increment of water production over time, which is associated with the increase in emulsion volumes, the need for technology able to overcome these challenges becomes paramount. In this study, the flow characteristics of a nanoparticle-stabilized water-oil emulsion were investigated for different nanoparticle concentrations and water fraction. The influence of different concentrations of silica dioxide nanoparticles on the pipeline flow behavior of emulsions was studied in a 13-m horizontal pipe with the inlet diameter of 0.0145 m. The effect of nano-silica (1, 3, and 5 wt %) on the emulsion stability, rheological type, viscosity, and pressure drop as well as on the energy consumption (for the water volume ratios of 35 and 50% v/v) was also investigated. The study showed that as the water cut increased, the viscosity of the produced oil increased proportionally to the water/oil volume ratio. Use of nanoadditives provided the viscosity reduction for two water cuts (35 and 50%). In the case of a 50% water cut, addition of 3% of nano-silica provided the most significant trend in reducing viscosity. In the case of addition of 1% nano-silica to a 35% water cut, the viscosity level decreased, and the shear-thinning behavior was observed for all the prepared emulsions. Nevertheless, the most significant amount of stable emulsion was produced at a water ratio of 35%, when a 3% nano-silica was added. The results also show that the addition of nanoparticles caused a decrease in the pressure drop, and the addition of 3% of nano-silica resulted in a highly stable emulsion and increased power consumption by a pump.

纳米粒子对乳液管道流动特性影响的实验研究

摘要考虑到油井的寿命和随着时间推移而增加的产水量（这与乳化液量的增加有关），对能够克服这些挑战的技术的需求变得极为迫切。本研究调查了不同纳米颗粒浓度和水分量下纳米颗粒稳定水油乳液的流动特性。此外，还研究了纳米二氧化硅（1、3 和 5 wt %）对乳液稳定性、流变类型、粘度、压降以及能耗（水体积比为 35 和 50% v/v）的影响。研究结果表明，随着减水量的增加，产出油的粘度与水/油体积比成正比增加。使用纳米添加剂可降低两种减水率（35% 和 50%）的粘度。在减水 50% 的情况下，添加 3% 的纳米二氧化硅可显著降低粘度。在减水 35% 的情况下添加 1%的纳米二氧化硅，粘度水平下降，所有制备的乳液都出现了剪切稀化行为。然而，在水比为 35% 时，添加 3% 的纳米二氧化硅能产生最大量的稳定乳液。结果还表明，添加纳米粒子会导致压降下降，而添加 3% 的纳米二氧化硅则会产生高度稳定的乳液，并增加泵的功耗。

期刊介绍： Petroleum Chemistry (Neftekhimiya), founded in 1961, offers original papers on and reviews of theoretical and experimental studies concerned with current problems of petroleum chemistry and processing such as chemical composition of crude oils and natural gas liquids; petroleum refining (cracking, hydrocracking, and catalytic reforming); catalysts for petrochemical processes (hydrogenation, isomerization, oxidation, hydroformylation, etc.); activation and catalytic transformation of hydrocarbons and other components of petroleum, natural gas, and other complex organic mixtures; new petrochemicals including lubricants and additives; environmental problems; and information on scientific meetings relevant to these areas. Petroleum Chemistry publishes articles on these topics from members of the scientific community of the former Soviet Union.
