摘　　要：成熟指数MI值是通过测井方法获得的反映页岩气层成熟程度的一个地球物理指标。通过介绍MI值在美国barnett页岩气储层研究中的应用情况,提出了利用MI值划分页岩气源岩的成熟度界限和烃相的方法;阐述了成熟指数MI值的应用原理和意义,表明MI值对热成熟度的反映原理主要基于页岩独特的生储方式;例举了MI值在国内的应用实例,进一步指出了MI值对页岩气有利气藏的预测和勘探具有指导意义。The Maturity Index MI is a geophysical index calculated from well-log data. Using Barnett Shale as an example, we introduced the application of Maturity Iridex MI in the reservoir research. The hypothesis for the application of the Maturity Index MI is described. The Maturity Index MI of a shale is a function of the source and accumulation system. An example is selected from China as a case to show the application of MI in resource assessment and exploration.
