红—克长输玻璃管线沿程压力和温度分布影响因素分析

为确定红—克长输玻璃管线常温输送方案，根据现场管线工况，利用Pipephase 软件建立了管道数值仿真模型，分析了原油含水率、输送流量、管道内壁粗糙度、环境 温度、入口温度等因素对管线沿程压力和温度分布的影响规律。结果表明:原油含水率 、输送流量、管壁粗糙度的增加会导致管线沿程压降增大；环境温度、入口温度的增加 会造成管线沿程压降减小，且压降变化趋势基本一致；原油含水率、入口温度的增加， 会引起管线沿程温降的增大；输送流量、环境温度的增加，会造成管线沿程温降的减小 ；管壁粗糙度对管线沿程温降影响较小。该研究工作为玻璃钢管线长输方案的制定提供 了参考依据，对保障油气安全运输具有重要的工程意义。

Analysis on influence factors for pressure and temperature distribution along the Hong-Ke long distance fiberglass pipeline

In order to determine the transportation scheme of Hong-Ke long distance fiberglass pipeline at normal temperature, the Pipephase software was applied to establish the numerical simulation model of pipeline according to the working condition of field pipeline. The influence laws of water cut in crude oil, transportation flow, roughness of inner wall, environment temperature and inlet temperature on the pressure and temperature distribution along the pipeline were analyzed. The results showed that the increase of water cut in crude oil, transportation flow and roughness of inner wall could lead to the increase of pressure drop along the pipeline, while the increase of environment temperature and inlet temperature could cause the decrease of pressure drop along the pipeline, and the change trends of pressure drop were basically identical. The increase of water cut in crude oil and inlet temperature could cause the increase of temperature drop along the pipeline, while the increase of transportation flow and environment temperature could lead to the decrease of temperature drop along the pipeline. In addition, the roughness of inner wall had less effect on the temperature drop along the pipeline. The research provides a reference basis for establishing the long distance transmission scheme of fiberglass pipeline, and it has important engineering significance to ensure the safety of oil and gas transportation.
