Low-molecular flow improvers for crude oil are becoming increasingly important chemical agents for crude oil production in oil fields. In this work, three alkyl benzene sulfonates were synthesized and evaluated as flow improvers for crude oil. The results show that the three flow improvers have an effect on L8401 crude oil (heavy oil). Among them, aluminium dodecylbenzene sulfonate (AlDBS) has the best effect as it reduces the viscosity rate by more than 80%. After adding 900 mg/L AlDBS, the freezing point is lowered by 15 °C. The crude oil flow improvement was proven with microphotographs. The co-crystallization behavior after addition of the agent interacts with the saturated hydrocarbons in the crude oil, which is the reason for lowering the freezing point of crude oil. Moreover, infrared spectroscopy and differential scanning calorimetry analysis (DSC) were used to illustrate the interaction mechanism between low-molecular flow improvers for crude oil and the components in crude oil.

烷基苯磺酸铝的合成及其作为原油流动改进剂的性能
用于原油的低分子流动改进剂正在成为油田原油生产中越来越重要的化学试剂。在这项工作中,合成了三种烷基苯磺酸盐,并对其作为原油流动改进剂进行了评估。结果表明,三种流动改进剂对L8401原油(重油)均有影响。其中,十二烷基苯磺酸铝(AlDBS)效果最好,可降低80%以上的黏度。添加 900 mg/L AlDBS 后,冰点降低 15 °C。用显微照片证明了原油流动性的改善。加入剂后的共结晶行为与原油中的饱和烃相互作用,是降低原油冰点的原因。而且,
