摘要:

针对耐温聚乙烯管道在油田集输系统应用中缺乏专用热力水力计算模型的现状,通过现场实验对其集输油过程中的水力摩阻特性与热力温降规律进行了量化分析。基于多参数变量实验数据,系统研究了流体物性、含水率、输送温度、流量等关键参数对管道压降及温降的影响机制,首次建立了适用于耐温聚乙烯材质的管壁总传热系数计算体系;利用PIPEPHASE软件构建仿真模型库,通过对比不同边界条件下理论预测数据与实测数据的偏差,筛选并修正了适用于该材质的摩阻计算模型与热传导模型,为耐温聚乙烯管道的工艺设计与安全评估提供了具有工程应用价值的理论支撑。

关键词: 聚乙烯, 含水率, 流动特性, 传热特性, 水力修正模型

Abstract:

To address the lack of specialized thermal?hydraulic calculation models for temperature?resistant polyethylene pipelines in oilfield gathering and transportation systems,this study conducted quantitative analysis on their hydraulic friction characteristics and thermal temperature drop patterns during oil transportation through field experiments.Based on multi?parameter experimental datasets,systematic investigations were performed to reveal the influence mechanisms of key variables including fluid properties, transportation temperature,rate of water content,and flow rate on pipeline pressure drop and temperature decline.For the first time,a calculation framework for the overall heat transfer coefficient applicable to temperature?resistant polyethylene (TRPE ) materials was established.Simulation model libraries were constructed using PIPEPHASE software,followed by comparative analysis of deviations between theoretical predictions and field measurements under varying boundary conditions.Through this process, friction calculation models and heat conduction models tailored for TRPE materials were selected and optimized,which provide valuable theoretical support for the process design and safety evaluation of TRPE pipelines in engineering applications.

Key words: Polyethylene, Rate of water content, Flow characteristics, Heat transfer characteristics, Hydraulic correction model
