摘要
针对经典的分析法溢油蒸发模型,对溢油初始沸点温度T0参数和蒸馏曲线梯度TG参数进行了修正,建立了考虑溢油粘度、蜡含量、沥青质等属性的修正公式;基于渤海"冀东32-6"和"绥中36-1"2种油样,对无风速情况下传质系数K2的修正常数R给出了估计范围。初步检验结果表明,改进模型数值结果更接近实验值。
To start with the oil spill evaporation model of classic analysis method,its parameters,i.e.the initial boiling point temperature T0of oil spill and the distillation curve gradient TG,are amended.The ex-pressions respectively for the amended T0and TGare formulated,in which kinetic viscosity,asphalt,wax etc of the oil spill are considered and included.Furthermore,a constant Rwith its evaluated range,which is suitable in windless weather and applicable to the crude oil samples from the Jidong 32-6and Suizhong 36-1oil wells,is estimated for modifying the mass transfer coefficient K2in the model.It is shown in the preliminarily verified results that the calculated values from the improved model are consistent to the values determined in the laboratory.
