现代产量递减分析技术在敖南气井中的应用
|
摘要
敖南浅层气井测压资料不全,应用物质平衡法、弹性二相法等无法评价气井的动态储量。收集气井的井口产量、压力等数据,并检查与诊断合理后,应用现代产量递减分析法评价气井可动用储量。结果显示,采用现代产量递减分析方法与静态法评估结果基本一致。表明现代产量递减分析法对于评价无测压资料气井动态储量具有很好的准确性。
The pressure measurement data of Aonan shallow gas well are incomplete, and the dynamic reserves of gas well can not be evaluated by material balance method and elastic two-phase formula. After collecting wellhead production and pressure data of gas wells and checking and diagnosing reasonably, the modern production decline analysis method is applied to evaluate the available reserves of gas wells. The results show that the results of modern production decline analysis method are basically consistent with those of static method. It shows that the modern production decline analysis method has a good accuracy for evaluating the dynamic reserves of gas wells without pressure measurement data.
