摘要：页岩气藏储量是确定气藏开发规模和开发设计的必要参数，对于合理有效开发页岩气藏具有重要意义。在前人研究的基础上，建立了综合考虑吸附相视孔隙度、基质和裂缝孔隙体积随压力变化以及吸附相密度等因素的物质平衡方程。通过实例计算可知：考虑吸附相视孔隙度后，计算得到的基质中自由气储量大幅度减少，吸附气储量大幅度增加，总储量增加；面且吸附相密度、基质孔隙度和裂缝压缩系数对于储量的计算结果也有较

On the basis of the previous study achievements, the materi al balance equation was established considering such factors as the changes of the adsorbed-phase apparent porosity, matrix and fracture porosity volume with the pressure and moreover the adsorbed gas density etc. the case calculation shows that when considering the adsorbed-phase apparent porosity, the free gas reserves in the calculation-presented matrix decrease to a great deal, while those of the adsorbed gas reserves increase greatly, and moreover the total re serves rise as well; and furthermore the influences of the parameters including the adsorbed phase density, matrix po-rosity and fracture compression factor on the calculated results of the reserves are still rather serious
Key words: adsorbed phase density; crack; matrix; porosity; material balance equation; reserve calculation
