针对三塘湖盆地低渗透复杂岩性气藏试气资料少且获取难、产能分析利用率较低，开展了岩性气藏单井合理产能研究。通过分析一点测试法中变量α 对储层渗透率、有效厚度及表皮系数的敏感性得知，对于物性差异较大、边界和地层非均质严重的气藏，用一点法计算不可能得到反映各类气井特征的统一经验产能公式。文中通过综合修正等时产能试井与一点法产能试井方法来确定不同产层的合理产能，得 出：牛101 块—马1 块齐古组合理产能为1.5×10⁴ m³/d，头屯河组合理产能为1.0×10⁴ m³/d。

It is necessary to carry out reasonable deliverability study for a single well, since deliverability test of gas well in lowpermeability lithologic reservoirs is difficult and seldom and the capacity analysis data are little utilized. The sensitivities of characteristic parameters of single-point deliverability equation to permeability, effective thickness and skin coefficient are analyzed. The result shows that the common experience productivity formula is invalid for the gas reservoirs with different properties, complex boundary and strong heterogeneity. The modified isochronal test and the single-point method are integrated to determine the reasonable deliverability: the deliverability in Qigu Group in Niu 101-Ma 1 block is 1.5×10⁴m³/d, and it is 1.0×10⁴m³/d in Toutunhe Group.
