摘要

重质原油是一种复杂的流体混合物,含有高比例的沥青分子、硫和几种重金属,如镍、钒和氮。这些成分会对稠油从生产井口通过管道输送到早期加工设施产生负面影响,其中稠油的粘度范围从102厘泊(c.P)到105厘泊(c.P)以上,低API度小于20 API度。为了提高稠油的流动性或流动性效率,降低粘度系数是一种很有前途的方法。在实验研究中,将沙坎稠油与不同的溶剂在不同的浓度速率和不同的温度条件下进行调合。本实验研究的主要目的是分析溶剂(甲醇和甲苯)对稠油原油粘度的影响。结果表明,甲苯有较好的降粘效果,而甲醇溶剂对降粘效果影响较小。

The Effect of Diffrent Solvents on Shaikan Viscous Crude Oil Through Thermal Application
Heavy crude oils are complex fluid mixture with a high proportion of asphaltic molecules, sulfur and several heavy metals like nickel, vanadium, and nitrogen. These components will affect negatively transporting viscous crude oil from production well-head to early processing facilities through pipeline, whereby the viscosity of heavy crude oils is ranging from 102 centipoise (c.P) to more than 105 c.P and low API° gravity less than 20 API° degree. In order to increase the efficiency of viscous crude oil flowability or mobility, reducing the viscosity factor is a promising method. In this experimental study, shaikan viscous crude oil has been blended with different solvents under different concentration rates and different temperatures conditions. The main objective of this experimental study is analyzing the effect of solvents like (methanol and toluene) on the heavy oil crude viscosity. The results obtained exhibit that, there is good viscosity reduction achieved by toluene but methanol solvent had a minor impact on viscosity reduction.
