摘　　要：储气库库容量与工作气量是储气库建设的核心问题。对于低渗岩性气藏储气库建设,储气库库容量评价是研究的重点和难点。由于低渗气藏的关井压力恢复速度慢,在动态监测测压时,压力没有恢复到地层压力,造成计算的储量偏小,笔者将压力进行修正,使得压降法计算储量更加精准,由于频繁关井测压对产能建设有很大影响,针对测压数据少的问题,本文也进行了说明。The gas storage working gas storage capacity and gas storage are the core issue construction. For low permeability lithologic gas reservoir gas storage construction, gas storage capacity evaluation is key and difficult research. Since the shut-in pressure and low permeability gas reservoir recovery is slow, while dynamic monitoring manometry, pressure is not restored to the formation pressure, resulting in the calculation of reserves too small, I will correct reservoirpressure, making storage more accurate method to calculate the pressure drop due to frequently shut manometry has a great impact on capacity building for less manometry data, this paper also described.
