摘　　要：基于异常高压气藏物质平衡方程式，经变换整理得到以原始地质储量的倒数为斜率、累计有效压缩系数为截距的线性方程。该方法不需要考虑地层及流体压缩系数，仅需历史生产数据采川线性回归分析即可确定异常高压气藏的原始地质储量和累计有效压缩系数。通过实例应用和对比分析，证明提供的新方法实用有效。A linear equation is derived from the mass balance equation of abnormal high-pressure gas reservoirs, with the reciprocal of original gas-in-place reserve as the slope and the accumulated effective compaction coefficient as the intercept. With this method, original gas-in-place reserve and accumulated effective coefficient can be determined through linear regression analysis based on only production data, without considering the compaction coefficient of formation and fluid. The new method is proved effective through case application and comparison analysis.
