中文摘要：

在页岩气体系统在甲烷吸着上决定热成熟的效果，从福特堡盆的 Barnett 页岩孤立的类型 II 的二不同热成熟 kerogens 被用来在在经常的温度从 0 ～ 14 MPa 的压力下面测量甲烷吸附数量。一 kerogen 与 0.58% vitrinite 反射被称为李 C-5-1；其它与 2.01% vitrinite 反射被称为 Blakely#1 kerogen。结果建议 kerogen Blakely#1 的甲烷吸着能力比不成熟的 kerogen 李 C-5-1，和它的兰米尔常数和兰米尔最大值吸着数量高，它被为至少方形的方法适合测量数据到达，比不成熟的 kerogen 李 C-5-1 大。这可以与那 nanopores 在有机物的降级期间开口了被联系，并且它增加了 kerogen 的特定的表面区域。因此，过去成熟 kerogen 有更大的甲烷吸附能力。

英文摘要：

To determine the effect of thermal maturity on the methane sorption in shale gas system, two different thermal maturity kerogens of type II isolated from Barnett shale of Fort Worth Basin were used to measure the methane adsorption amount under the pressure ranging from 0 to 14 MPa at constant temperatures. One kerogen was called Lee C-5-1 with 0.58% of vitrinite reflectance; the other was called Blakely#1 kerogen with 2.01% of vitrinite reflectance. The results suggested that the methane sorption capacity of kerogen Blakely#1 was higher than the immature kerogen Lee C-5-1, and its Langmuir constant and Langmuir maximum sorption amount, which were reached by fitting the measured data for at least square method, greater than the immature kerogen Lee C-5-1. This may be associated with that nanopores opened up during the degradation of organic matter, and which increased the specific surface area of kerogen. Therefore, the over mature kerogen has greater methane adsorption capacity.
