涩北气田携液临界流量计算模型优选

Optimization of Models for Calculation Critical Flow Rate of Carrying Liquids in Sebei Gas Field

在前人研究的基础上，应用现场实际生产数据，以井筒积液时间为标准，对Turner模型、李闽模型以及四相流模型进行了对比分析，从中优选出涩北气田适应性较强的临界携液流量计算模型。对比分析结果表明，李闽模型的预测结果与实际情况更加吻合，应用该方法能够更为准确地确定翠北气田气井的合理排水采气时机，对涩北气田的合理开发有一足的指导意义。

Based on the predecessors' studies,field production data were used and of 'loading time' was used as criterion to made a comparative analysis of three models,such as Turner model,LI Min's model and Four-phase flow model,from which the best model was selected for calculating the critical flow rate for Sebei Gas Field.The result indicates that as the result of comparative analysis,LI Min's model is approximately consistent with practical situation.The application of this method would determine the reasonable time of water drainage more accurately,it provides rational guidance for development of Sebei Gas Field.
