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。Besides the advantages such as short test time, relatively simple process and low cost etc., the single-point well test method cannot only reduce the amount of released air during test, but also effectively evaluate deliverability, so the method can be widely used in pro-ductivity 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-pointdeliverability formula is established for the gas field. According to the deliverability test results from 42 wells in S gas field, an average αvalue of 0.28 is obtained for the formula. Because the well deliverability varies greatly, α values should be classified and calculated accord-ing to different deliverability ranges. The single-point deliverability formula using the average α value of 0.28 and α values for differentranges can verify that the open flow capacities obtained from α values for different deliverability ranges are more accurate.
