研究了不同的替代方案对提高中粘原油流动性的影响。这些替代方案包括向原油中加入水以形成油包水乳液、加入轻质石油产品、加入流动改进剂和预热技术。在中等粘度原油的流动性增强研究中，研究了10-50 ℃的温度范围、0 - 50体积%的水浓度范围、0-5000 ppm的流动改进剂浓度范围和0- 50体积%的煤油浓度范围。使用来自Haake的RheoStress RS 100研究在粘度降低方面的流动性增强。使用锥板传感器，锥角为4度，锥直径为35 mm，锥尖处的间隙为0.137 mm。在原油中加入煤油比任何其他研究技术都能更好地改善流动性。
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 degrees 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 degrees 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.
