指数递减法在凝析油气藏中的应用

Application of Exponential Decline Method in Condensate Gas Reservoir

指数递减法是油气藏工程中的一个重要预测方法。它可以用于预测油气田递减阶段的产量、累积产量和可采储量。将指数递减用于凝析气藏的预测,取得了很好的效果,并得到了凝析气藏的总井流体产量、干气产量和凝析油产量的递减均符合指数递减的重要结论。

Expone nt ial decline is an important forecasting method in oil and gas reservoir enginee ring.It can be used for prediction of produc-tion,cumulative production and r ecoverable reserves in depletion stage.The method is applied in prediction of c ondensate gas reservoir,and better results have been obtained.It is concluded that the decline regularities of the total well fluid production,dry gas produc tion and conden-sate production accord with the exponential decline rule.
