摘要： 一点法试井具有测试时间短、工艺相对简单、成本低等优点，不仅减少了测试时的放空气量，而且能有效评价产能，故在气田产能评价中应用广泛，但各气田一点法产能公式中的α存在较大差异。为了将这一方法应用于阿姆河右岸S气田，对一点法产能公式进行了修正，建立了适于该气田的一点法产能公式。根据目前S气田42井次的产能试井成果，获取的S气田一点法产能公式中的平均α为0.28. 但由于S气田单井产能差别较大，根据产能高低进行分类，求得不同产能范围内的α，应用气田平均α为0.28和按照产能高低进行分类取得的α的一点法产能公式计算产能，验证了采用产能区间划分后取得的α计算的无阻流量更加准确。

Abstract: Besides the advantages such as short test time, relatively simple process and low cost etc., the single-point well test method can not only reduce the amount of released air during test, but also effectively evaluate deliverability, so the method can be widely used in productivity evaluation for gas fields. However, the value of α in the single-point formula is quite different in different gas fields. The single-point deliverability formula is modified for the application in S gas field of the Right Bank Block of Amu Darya and a unique single-point deliverability formula is established for the gas field. According to the deliverability test results from 42 wells in S gas field, an average α value of 0.28 is obtained for the formula. Because the well deliverability varies greatly, α values should be classified and calculated according to different deliverability ranges. The single-point deliverability formula using the average α value of 0.28 and α values for different ranges can verify that the open flow capacities obtained from α values for different deliverability ranges are more accurate
