Analysis and Evaluation of Temperature-Resistant Polyethylene Pipeline Operation in Oil Field
摘要
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.关键词
