| 摘 要： | 页岩气在形式上以游离气和吸附气并存,存储空间上为孔隙和裂缝同存。页岩气藏的产气机制主要为游离气的扩散以及吸附气的解吸。基于此,分析页岩气储量计算的方法,如类比法、静态法、动态法。重点分析动态法,探讨不同方法的适用条件。分析页岩气储量计算中的几个关键因素,简要介绍其确定方法。

| Abstract: | In existence form,coexistence of free gas and adsorbed gas are in the same period.In form of storage space,pores and fractures exist at the same time.Production mechanism of shale gas is the proliferation of free gas and desorption of adsorbed gas.On this basis,the calculation for shale gas reserves include Analogy,the static method,dynamic method.This paper analyzes the dynamic method,and explores the conditions of application for different methods.In addition,it analyzes several key factors which should be paid special attention to in shale gas reserves calculation,and introduces how to confirm these parameters in brief. |

| Keywords: | shale gas reserves static method dynamic method cleft adsorbed gas content |
