多项地球化学测试分析表明,研究区内的煤岩以脂质组和富氢镜质组占优势,绝大多数属于Ⅱ型有机质,少数接近于Ⅰ型有机质。综合分析结果显示,该区的煤具有良好的成烃条件。研究区内业已发现的以煤成油占优势的工业油气藏进一步证实了该区Es_3上段的煤具良好的成烃潜力。
A number of geochemical tests show that the coal and rock in the study area are dominated by lipid groups and hydrogen-rich vitrinite groups, most of which belong to type II organic matter and a few are close to type I organic matter. The comprehensive analysis shows that the coal in this area has good hydrocarbon generation conditions. The industrial hydrocarbon reservoirs, which have been found to dominate coal-to-oil production in the study area, further confirm the good hydrocarbon generation potential of the coal in Upper Es_3 area.
