- 摘要:
- 以NP1-3D至NP1-1D人工岛间海底混输管道为例,利用PIPEFLO多相流模拟软件,计算分析了影响油气水混输管道压降的主要因素,即流体黏度、管径、气液比及起输温度等对海底混输管道稳态压降的影响。分析认为,当输送流体的气液比处于某一区域内,能够降低混输管道沿程压降;对于气液混输管道,起输温度的升高并不一定引起压降的降低;管径对混输管道压降影响重大,在设计中应综合考虑油田整体开发规划和特点,合理确定混输管道的管径。
Taking the NP1-3D to NP1-1D subsea multiphase pipeline for example, PIPEFLO multiphase flow simulation software is utilized to analyze the influences of different diameter, fluid viscosity, gas-oil ratio and inlet temperature on the pressure drop calculation for subsea multiphase pipeline. When gas-oil ratio is within a certain range, the multiphase pressure drop along the pipeline can be reduced; when the inlet temperature goes up, the pressure drop in subsea oil-gas multiphase pipeline does not always reduce; the diameter of multiphase pipeline produces an important effect on the pressure drop, so the overall oilfield development planning and characteristics should be considered in order to determine the diameter of a subsea oil-gas multiphase pipeline.2011,S1(S1): 21-24 收稿日期:2011-8-23分类号:TE832.3作者简介:林燕红(1983- ),女,福建福州人,助理工程师,2008年毕业于中国石油大学油气储运专业,硕士,现从事海洋工程设计工作。参考文献:
