Abstract

Emulsion formation is a natural phenomenon since crude oil is constantly produced in conjunction with water from the reservoir. Water-in-oil (W/O) emulsions have been claimed to be the most prevalent form of emulsion seen in the oil and gas industry. It can exhibit high viscosity, leading to challenges during pipeline transportation as well as in oil sector. In this paper, the effect of modified silica dioxide (SiO₂) and magnesium oxide (MgO) nanoparticles with different concentrations (1, 3, and 5 wt %) on the flow characteristics of east Baghdad crude oil emulsion have been investigated with water cut 35% v/v in a 0.0145 m inner diameter and 13 m length horizontal pipe. The effect of these nanoparticles on the emulsion stability, rheological, type, viscosity, and pressure drop as well as energy consumption was also studied. The rheology study found that best results were achieved by using modified nano silica at 1 and 3% addition, which resulted in significant reduction of viscosity with shear thinning behavior. Indeed, that the addition of modified nano silica decreased the pressure drop and the addition of 3% results in high stable emulsion and pump power consumption.

氧化镁和表面改性二氧化硅纳米颗粒对东巴格达原油乳液稳定性、流变性、能耗和流动性的影响

摘要乳状液的形成是一种自然现象，因为原油是与储层中的水一起不断生产出来的。油包水（W/O）乳状液据称是石油和天然气行业中最常见的乳状液形式。它可以表现出很高的粘度，从而给管道运输和石油行业带来挑战。本文研究了不同浓度（1、3 和 5 wt %）的改性二氧化硅（SiO2）和氧化镁（MgO）纳米粒子对巴格达东部原油乳液流动特性的影响，在内径为 0.0145 米、长度为 13 米的水平管道中，含水量为 35% v/v。还研究了这些纳米颗粒对乳状液稳定性、流变性、类型、粘度和压降以及能耗的影响。流变学研究发现，使用改性纳米二氧化硅（添加量为 1%和 3%）可获得最佳效果，显著降低粘度，并具有剪切稀化行为。事实上，添加改性纳米二氧化硅降低了压降，而添加 3% 的改性纳米二氧化硅则使乳化液更加稳定，同时降低了泵的能耗。

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.
