| 摘 要： | 针对塔河油田一号联合站至雅克拉集气处理站凝析油输送管道结蜡严重的问题，探讨了结蜡层厚度的计算方法、模型及其优劣。利用列宾宗公式反算平均蜡层厚度可大致掌握管道的实际结蜡情况；黄启玉模型的参数确定需要大量的实验数据支撑，计算量和误差较大；双曲正切结蜡模型对含蜡油品热输管道的结蜡分布模拟适用于工程计算。运用双曲正切结蜡模型和数值计算方法模拟分析了该管道的结蜡情况，给出了计算步骤和计算结果，证明了整条管道结蜡的不均匀性。根据分析结果，该凝析油输送管道可长期不清蜡，且不会影响其停输再启动操作。

| Abstract: | Investigation shows that the wax deposition in the condensate pipeline from No.1 Complex Station to Yakela gas gathering and processing station in Tarim Oilfield is serious.The calculation method and model for wax deposition layer thickness and their advantages and disadvantages are discussed.It is considered that Leapienzon Formula can be utilized to inversely calculate average wax layer thickness,by which,to grasp the actual wax deposition situation of pipelines.The determination of parameters by Huangqiyu Model requires the support of huge quantities of actual experimental data,the calculation amount is great with obvious error,and hyperbolic model of wax deposit is applicable to the engineering calculation for the wax deposition distribution simulation referring to hot waxy oil pipeline.This paper simulates and analyzes the wax deposition situation of this pipeline with hyperbolic wax deposition model,and provides the calculation steps and calculation results,so as to verify the unevenness of wax deposition along the whole pipeline.According to the analysis results,longterm running with wax deposit is allowed for this condensate pipeline,which will not impact the shut-down and restart up operation of the pipeline. |
