| 摘 要： | 利用高压吸附仪对新疆主要沉积盆地侏罗系煤储层的甲烷吸附能力进行了测试。测试结果表明中低变质煤的吸附能力普遍较低 ,且吸附能力随煤镜质组反射率值的增加而增加 ,随煤中水分的增加而减小 ,其原因与煤的微孔特征有关。根据煤储层的吸附兰氏体积 ,新疆侏罗系煤储层可分为 4类区 ,并认为新疆具有煤层气资源前景的地区分布在煤的吸附兰氏体积大于 12m3 /t的第三类区及第四类区

| Abstract: | The adsorbability to coalbed methane of low-middle metamorphic Jurassic coal reservoirs in main basins in Xinjiang has been studied using high-pressure adsorption instrument. The results indicate the adsorbability of coal in the region is relatively low, and increasing with vitrinite reflectance and decreasing with moisture in raw coal. It is probably related with micropore characteristics of coal. Four sub-areas of coal reservoirs in Xinjiang have been divided according to the Langmuir volume. The favorable areas for coalbed methane resources distribute in the third and fourth subareas with larger than 12 m 3 per ton Langmuir volume in Xinjiang. |
