| 摘 要： | 利用计算机模拟系统对沁水盆地中南部煤层气的聚散演化史进行了定量模拟研究。结果表明，模拟区煤层气聚散史可分为4个演化阶段，即煤层气聚集作用微弱的第1，2阶段、各种演化作用发育且聚集作用强烈的第3阶段以散失作用为主的第4阶段。区内地史中煤层气聚散演化作用强烈的部位及其聚集相对较强。模拟区南部和北部的中区是煤层气聚集的有利地区。

| Abstract: | The concentration dissipation history of coal bed methane (CBM) in the middle southern Qinshui Basin was quantitatively simulated. The result indicates that the whole concentration dissipation history can be divided into four stages, that is, stage one and two with a weak concentration of CBM, stage three with various intensive evolutions and a high level of concentration of CBM, and stage four in which the main evolution action is dissipation. In the research region, the loction where the CBM concentration dissipation action is strong has a strong concentration of CBM. The southern part and the middle area of the northern part are promising area for CBM concentration. |
