WellFlo与PIPESIM管流关系式预测结果对比分析

Comparative Analysis on Predicted Results of Multiphase-flow Relationships in WellFlo and PIPESIM

根据误差分析方法建立多相管流关系式综合评价模型,该模型包含了3个衡量误差的性能指标。利用中海油锦州地区、渤中地区及平湖地区116井次实测数据分别对WellFlo和PIPESIM软件多相管流关系式进行评价,并对其预测结果进行对比分析,结果表明:依据各地区性能最佳的关系式比较,PIPESIM较WellFlo软件管流关系式预测结果略好;但从排在前9位的WellFlo软件均占6位看,WellFlo软件管流关系式预测结果较PIPESIM软件略好。

Based on error analysis,the comprehensive evaluation model of multiphase pipe-flow correlations is presented.It contains 3 performance indexes to weight error.By means of the 116 sets of tested data in Jinzhou,Bozhong and Pinghu areas,the paper has carried respectively on evaluation on the multiphase pipe-flow correlations of WellFlo and PIPESIM.On this basis,the comprehensive comparative analysis of multiphase pipe-flow correlations of two softwares is carried,the results show that according to the number of best correlations,PIPESIM is better a bit than WellFlo.However,both in the Jinzhou,Bozhong and Pinghu areas,the 6 correlations in the forer 9 belong to WellFlo,therefore WellFlo is slightly better than PIPESIM from this point.
