- 【目的】电场改性是一种新兴的含蜡原油低温流动性改善方法。此前针对酒东原油研究发现，电场输入能量密度是含蜡油电场降黏效果的外部决定性因素，且当输入能量足够大时，电场处理可使油样达到该温度下的最大降黏率，为指导原油电场改性的工业应用，需进一步验证该结论对其他原油的适用性。【方法】针对长庆原油与大庆原油，通过探究不同电场处理条件（场强：0~3 kV/mm，电场处理时间：0~1 200 s，处理量：1~2.5 mL）对原油电场降黏效果影响，研究并验证输入能量与降黏率的关系。【结果】首次发现并定义了最大降黏率能量密度阈值，即原油达到最大电场降黏率所需输入的最小能量密度。明确了处理温度（累计析蜡量）对最大降黏率与相应能量密度阈值的影响。随着处理温度降低，最大降黏率增大，相应的能量密度阈值减小。结合显微观察与带电胶粒运移、吸附机理，分析其内在原因。这是由于在较低处理温度下，有更多的蜡晶颗粒受到胶质、沥青质作用；更多、更大的蜡晶导致电场作用下蜡晶表面出现更多电荷，从而促进胶质与沥青质在介电泳作用下向蜡晶表面运移，并积聚在蜡晶表面，因此最大降黏率增大且所需能量密度阈值更小。【结论】研究结果深化了对原油电流变效应机理的认识，能量密度阈值的发现为处理器电源参数确定与优化提供了重要参考。
- Abstract:
- [Objective] Exposing a waxy crude oil to an electric field represents an emerging strategy for improving the cold flowability of oil. A previous study on Jiudong crude oil found that the input energy density of the electric field is the essential factor determining the viscosity reduction induced by electric fields, and a same maximum viscosity reduction at that temperature can be achieved eventually as long as the input energy is sufficient. To offer guidelines for the pilot and industrial testing of electric treatment, further validation of the applicability of the findings to other crude oils is required. [Methods] The relationship between input energy and viscosity reduction for Changqing and Daqing crude oils was investigated and confirmed by examining the effects of various electric field treatment conditions (field strength: 0–3 kV/mm, treatment time: 0–1200 s, and treatment volume: 1–2.5 ml) on the viscosity reduction. [Results] For the first time, the energy density threshold for the maximum viscosity reduction, i.e., the minimum energy density input required for crude oil to achieve maximum viscosity reduction under electric fields, was identified and defined. With decreasing treatment temperature, the maximum viscosity reduction increases, while the corresponding energy density threshold decreases. The intrinsic reasons were analyzed by combining microscopic observation with the transport and adsorption mechanism of charged colloidal particles. At lower treatment temperatures, more wax particles were subjected to the action of resins and asphaltenes; more and larger wax particles resulted in more charges on their surfaces induced by the electric field, which promoted the transport of resins and asphaltenes to the surfaces of the wax particles under the action of dielectrophoresis and accumulation on the wax particle surfaces, and thus the maximum viscosity reduction increased and the required energy density threshold was decreased. [Conclusion] These new findings facilitate further understanding of the negative electrorheological effect and its mechanism of crude oil. The disclosure of energy density thresholds offers valuable guidance for determining and optimizing the power parameters of the electric treaters.
