摘　　要：在Blasingame和Rushing提出的半解析方法(产量—累计产量模型)与Ilk等人提出产量递减模型的基础上,推导出适合低渗透气藏地质储量计算模型——无因次产量—累计产量关系和无因次指数递减典型曲线。通过实例分析得知,计算出的地质储量与产量累积法计算出的地质储量很接近,说明该方法具有一定的适用性与可靠性。On the basis of the semi-analytical methods(flow rate cumulative production model) created by Blasingame and Rushing and the model of production decline created by Ilk et al,a new model for estimation of gas reservoir with low permeability,i.e.relationship between dimensionless flow rate and the cumulative production and the dimensionless typical decreasing index curve,is derived.And the field example analysis showed that the estimated reserves by this method are very close to those calculated by cumulated production method,which indicates that the method is quite applicable and reliable.
