摘要

单相气体产能方程有其自身的局限性。广泛使用的压力和压力平方法是对气井在不同的压力区间通过简化而得到的;尽管单相气体拟压力产能方程采用了更严格的处理方法,但也不再适用于油、气、水多相渗流。为此,提出了广义的拟压力函数,从而导出适用于气井多相渗流的产能方程。通过实例计算证明该方法是正确、可行的。

Abstract

The deliverability equation of single-phase gas has its limitation.The pressure and pressure square deliverability equations are widely used at present,but they are simplified in various pressure interval.Though stricter processing method has been adopted,the pseudo-pressure deliverability equation of single-phase gas is not suitable to multiphase percolation.Therefore,the function of generalized pseudo-pressure is hold up,and corresponding deliverability equation for multiphase percolation is derivated.The formulary validity is tested and verified by an example.
