【摘要】 根据山西煤田实际资料 ,建立了推算山西煤盆地最高古地温的数学模式 ,探讨了区内热演化史 ,提出了山西煤盆地于成煤期后 ,曾有两次大的热演化过程 ,一为印支期 ,主要是快速沉降堆积增温阶段 ;一为燕山期 ,主要表现为岩浆区域热叠加增温现象 ,煤层气相应出现两个生成高峰期更多还原

【Abstract】 On the basis of the relerant information, formulated the mathematical pattern of the highest paleogeotemperature of Shanxi Coalfield, the history of the regional thermal evolution is discussed. It is presented that the two main evolutionary stages took place after coalforming,one is IndoSinian period, another is Yanshanion,in which the thermal of regional magma indmed temperaturerising.Both of them are generating climax of coalbed gasses.
