构造-地热-煤变质演化配置研究表明．在燕山期岩浆异常热影响区块，鄂尔多斯盆地东缘古生代保的煤层气发生量显著．主产气时段集中.二次生烃作用不仅制约着生烃强度，同时决定了煤层气优越的富集和保存条件。
Structural - geothermal - coal metamorphic evolutionary configuration studies have shown. During the Yanshanian magmatic anomalous heat-affected zone, the occurrence of Paleozoic coalbed gas in the eastern margin of Ordos Basin is significant. The main gas production period is concentrated.The secondary hydrocarbon generation not only restricts the hydrocarbon generation intensity, but also determines the superior enrichment and storage conditions of CBM.
