惠民凹陷南坡石炭二叠系煤层二次生气模式

Gas generation model of Permo-Carboniferous coal in south slope of Huimin Sag

利用开放体系程序升温热模拟实验方法,对惠民凹陷南坡石炭—二叠系煤岩样品的热演化规律进行了研究,建立了该区石炭二叠系含煤地层有机质的生气模式,探讨了影响二次生气潜力的各种主控因素,为准确评价其资源潜力和计算远景资源量奠定了基础,对渤海湾盆地其他类似地区煤型气勘探具有指导意义。

An open system with programming temperature raising apparatus is used in this simulation experiment of thermal evolution of organic matters. Based on experiment results, a deep research on the thermal evolution of Permo - Carboniferous coal in the south slope of Huimin Sag has been conducted. The gas generation model is established and the influence factor of the second gas generation potential is discussed. This work gives a base for evaluation of resources potential and calculation of resources, and this work will also direct the exploration in similar area such as the other parts of Bohai Bay Basin.
