和什托洛盖盆地上石炭统太勒古拉组烃源岩生气层主要为黑色富有机质凝灰质泥岩、页岩。通过对烃源岩的分布、厚度变化规律及有机地化特征研究,评价其生气潜力。在前人研究基础上,结合本次综合分析显示,烃源岩赋存较好,但分布不连续,有机质丰度较高;有机质类型以Ⅲ型腐殖类为主,少量Ⅱ_2型、Ⅰ_1型;有机质热演化程度属成熟-高成熟阶段;脆性矿物含量为高-特高值,具一定生气潜力。
And the Upper Carboniferous Leleugula Formation source rocks in the Storligai Basin are mainly black organic-rich tuffaceous mudstone and shale. By studying the distribution of source rocks, the variation of thickness and the characteristics of organic geochemistry, the potential of gas generation is evaluated. Based on the previous studies, combined with this comprehensive analysis, the source rocks are well-preserved, but their distribution is discontinuous and the organic matter abundance is high. The organic matter types are mainly type Ⅲ, a small amount of type Ⅱ_2, type Ⅰ_1 ; The degree of thermal evolution of organic matter is mature - high maturity stage; brittle minerals are high - extra high value, with certain potential for anger.
