气藏动态储量是指参与渗流的地下气体地质储量，计算动储量常采用物质平衡法，但是对于难以获得平均地层压力的致密气藏不适用。本文介绍了利用气井长时间生产数据计算动态储量的方法，并研究采用叠加时间函数（Super-t）分析变产量修正时间，使计算结果更加精确；同时应用该方法对苏东南区致密砂岩气藏部分气井进行单井动态储量计算，为该区动储量估算提供借鉴。

The OGIP is refers to the gas geological reserves in seepage underground. The material balance equation is usually used to determine the OGIP, however, it is no longer applicable in tight gas reservoir because the average reservoir pressure is usually unknown for the long transient periods. So the authors try to estimate OGIP from long-term production data in the paper, and use the superposition time (Super-t) function to analyze the variable flow rate and correct the time to make the result rigor. The authors also use production data from Su Southeast Gas Reservoir to estimate single-well OGIP and provide reference for the determination of OGIP.
