The potential of gas generation from coal bearing formation in Huimin Sag

  • 摘要: 从有效气源岩的概念出发,通过实验测定了该区含煤地层最大吸附气量,结合模拟实验中产气量与总有机碳(TOC)、热解生烃潜力(S1+S2)、氢指数(HI)、最大镜质组反射率(Rmax)等指标的相关关系,提出了不同演化阶段煤系地层有机质生气潜力下限及各指标适用范围,并据此对惠民凹陷石炭二叠系煤岩、泥岩等气源岩进行了评价,证实了该区煤岩和泥岩可以作为有效气源岩。该成果对该区的煤型气勘探有一定指导作用,对渤海湾盆地其他地区煤系源岩评价也有一定参考价值。
    Abstract: There are large areas being of thick coal beds in Huimin Sag,but there are no uniform and effective standards for the potential evaluation of gas generation.In this article the concept of effective gas source rock is outlined,the maximum gas adsorption volume of caol beds is determined by experiments,the lower limits of gas generation potential of coal beds are put out and their available application scope are point out under different evolution stages combined with the relationship of gas generation rate and indicators (such as S 1+S 2,HI and R max) in thermal simulation experiment.The gas generation potential of coal beds is evaluated according to these standards,this confirms an idea that the coal beds in this area can act as effective gas source rocks.This work will push on the exploration of coal soured gas in this area and will be valuable referencs for the coal soured gas exploration in other parts of Bohai Gulf Basin.
