Abstract

The high viscosity of heavy crude oil has been an obstacle to its safe production and economic transportation. In this work, a screened emulsified viscosity reducer system is conducted. Experimental results demonstrate that the most effective viscosity reducing agent comprises sodium oleate (NaOl) and cocamidopropyl betaine (CAB-35) in a ratio of 1:2, achieving a viscosity reduction rate of 94.65%. Additionally, the interfacial tension between oil and water decreases from 27 to 4 mN/m with 0.1 mass % TEOA and NaOH in a 1:1 ratio. The oil droplet size is uniformly distributed with is 14 μm and is 11 μm. Droplets flocculate as the salinity increases to 0.2 mol/L, which corresponds to the apparent increase of viscosity. The adsorption of long alkyl chain lipophilic groups on surfactant molecules at the oil-water interface and the water film alters the wettability of pipe steel to water-wet, further enhancing the application of emulsification and viscosity reduction effects. The primary mechanism behind the viscosity reduction in emulsification is attributed to strong electrostatic interactions stemming from molecular electrostatic potential distributions.

摘要

重质原油的高粘度一直是其安全生产和经济运输的障碍。在这项工作中，开展了一种筛选出的乳化降粘剂体系。实验结果表明，最有效的降粘剂由油酸钠（NaOl）和椰油酰胺丙基甜菜碱（CAB - 35）按1:2的比例组成，降粘率达到94.65%。此外，在含有0.1质量%三乙醇胺（TEOA）和1:1比例的氢氧化钠的情况下，油水界面张力从27 mN/m降至4 mN/m。油滴尺寸均匀分布，平均直径为14μm，标准偏差为11μm。当盐度增加到0.2 mol/L时，液滴絮凝，这对应着粘度的明显增加。表面活性剂分子上长烷基链亲油基团在油水界面和水膜上的吸附改变了管道钢对水的润湿性，使其变为水湿，进一步增强了乳化和降粘效果的应用。乳化降粘背后的主要机制归因于分子静电势分布产生的强静电相互作用。
