摘要
在不能用原始气藏压力下的产能方程式代替当前气藏压力下的产能方程的情况下 ,提出了用测压资料回归当前气藏压力下的产能方程的新方法。并介绍了该方法的原理及用GT软件计算当前气藏压力下产能的操作方法 ,通过计算实例 ,结果表明 ,该方法针对性和适应性强 。
For productivity equation at primary formation pressure can’t calculate productivity at present formation pressure,a new method of calculating productivity at present formation pressure is proposed by using regress testing data of pressure.The paper introduces the method’s principle,and operating method of calculating productivity at present formation pressure by using GT software.Through calculation,the results show the method is correct and effective.
