陕甘宁盆地现用的确定天然气并绝对无阻流量的系统试并方法和低回压“单点”测试法，存在所需测试时间长，国压低；使大量天然气放空的问题。文章以气井指数式流动方程为理论依据，以实际系统试并资料为基础，总结出用“单点法”测试计算陕甘宁盆地天然气井绝对无阻流量的方法。该方法在任何回压条件下，基本上可以取得与系统试并一致的绝对无阻流量，弥补了低回压“单点法”测试的不足。

A NEW METHOD OF DETERMINING GAS WELL AOF IN SHANGANNING BASIN

The system well testing method and"single point"testing method with low back pressure of determing gas well AOF used in Shanganning Basin are of the problems of time-consuming,low back pressure and blowing-down a lot of gas. Based on the theory of gas well exponential flowing equation and the practice well-logging data.a new"single point"testing method of computing the gas well AOF in Shanganning then is summaried. The AOFobtained by the new method is roughly the same with that by the system well-testing in any back pressure conditions toovercome the defects of "single piont" testing with low back pressure.
