摘要

摘要研究了提高中等粘度原油流动性的不同选择。这些替代方法包括在原油中加水形成油包水乳化液、添加轻质石油产品、添加流动性改进剂和预热技术。在中等粘度原油的流动性增强研究中，研究了温度范围为10 ~ 50℃，水体积浓度范围为0 ~ 50%，流动改进剂体积浓度范围为0 ~ 5000ppm，煤油体积浓度范围为0 ~ 50%。利用Haake公司的流变应力RS100研究了通过降低粘度来提高流动性的方法。采用锥板传感器，锥角为4°，锥径为35 mm，锥尖间隙为0.137 mm。在原油中加入煤油比任何其他已研究的技术都能更好地改善原油的流动性。

Flow Enhancement of Medium-Viscosity Crude Oil

Abstract This study investigated the different alternatives to enhance the flowability of crude oil with medium viscosity. These alternatives include the addition of water into crude oil to form water-in-oil emulsion, the addition of light petroleum product, the addition of flow improver, and a preheating technique. Temperature range of 10–50°C, water concentration range of 0–50% by volume, flow improver concentration range of 0–5000 ppm, and kerosene concentration range of 0–50% by volume were investigated in the flowability enhancement study of crude oil with medium viscosity. The flowability enhancement in terms of viscosity reduction was investigated using RheoStress RS100 from Haake. A cone–plate sensor was used with a cone angle of °4, cone diameter of 35 mm, and 0.137-mm gap at the cone tip. The addition of kerosene to crude oil improves the flowability much better than any other investigated technique.
