摘　　要：通过物质平衡原理推导了广义视压降法储量公式,利用该公式分析开发早期气藏动态储量,其计算误差的影响因素主要为气藏含气孔隙体积变化率与气藏压力,同时制作了典型气藏开发早期动态储量校正图版。采用该图版对安得森"L"气藏动态储量进行计算,结果表明,动态储量校正图版能够对早期视压降外推储量进行校正,计算结果可信度高,对气藏开发早期方案的制订有重要的指导意义。The paper has derived a gas reserve calculation formula with a general pseudo pressure decline method by using material balance principle.The formula can be used to analyze dynamic reserve calculation in early development stage of gas reservoir and the factors affecting the error of the analyses are mainly change rate of pore volume of gas and gas reservoir pressure.The paper has also made a typical correction chart for dynamic reserve calculation in early development stage of gas reservoir.The chart can be used to calculate dynamic reserve of Underson L gas reservoir.The calculation result shows that the chart can calibrate the extrapolation reserve of early pseudo pressure decline and the calculation result is reliable and significant to FDP of early stage of a gas reservoir.
