Abstract

The impact of production tubing diameter on multiphase flow regime profile is investigated. For a given isolated section of the production tubing in selected wells drilled and completed in Oredo fields, velocity profile and fluid flow characteristics at the production tubing centreline and along the pipe wall were evaluated. Complex flow behaviour is characterised by tubing diameter and asymptotic flow pattern at the tubing surface where no-slip boundary condition was imposed. Future inflow production performance relationship (IPR) and influence on vertical lift performance are determinable from the multiphase flow regime profiles. Furthermore, we investigate the impact of production tubing diameter on multiphase flow regime profile in Oredo oil field Nigeria. Mechanisms responsible for complex fluid flow behaviour and transition in different tubing configuration with implication on production optimisation and performance analysis are also included in the model design and analysis. From the results obtained in this study, it is evident that higher volume of oil is producible from bigger production tubing. However, implications on vertical lift performance and production optimisation require a more critical analyses.

尼日利亚尼日尔三角洲Oredo油田生产油管直径对多相流流态剖面的影响

研究了采油管径对多相流流型分布的影响。在Oredo油田的一些已钻完井中，对生产油管的特定隔离段进行了速度剖面和沿管壁的流体流动特性评估。在无滑移边界条件下，管径和油管表面的渐近流型是复杂流动特性的特征。未来的流入生产动态关系(IPR)及其对垂直举升性能的影响可以从多相流流型曲线中确定。在此基础上，研究了尼日利亚Oredo油田生产油管直径对多相流流态分布的影响。在模型设计和分析中，还包括了复杂流体流动行为和不同油管配置下的过渡机制，这意味着生产优化和性能分析。从研究结果来看，较大的采油油管可以获得较大的产油量。然而，对垂直举升性能和生产优化的影响需要更严格的分析。
