| 摘 要： | 用产能天然气井超完全覆盖射孔效果，受到孔段内储层参数和测试生产压差变化的影响。依据气井地面测试采气求取单位储层评价系数所具有的产能，用推导出的数学模型分别计算评价指标η1和η2，能精细描述射孔效果。

| Abstract: | In natural gas well,productivity evaluation for effect of overlap reperforations is affected by the changes of payzone parameters and producing pressure drawdown in perforated interval.In this paper,the production capacity of unit payzone parameters is calculated depending on surface testing gas productivity index.The reperforation effect can be described meticulously with index η1 and η2 which is calculated by the derived mathematical model. |
