伊犁盆地二叠系原始有机质丰度的热解模拟法恢复

Restoration for the Original Contents of Organic Matters in the Source Rock from Pamian in Yili Basin by Pyrolysis Simulation

目的：恢复伊犁盆地二叠系原始有机质丰度。方法：选用伊犁盆地未成熟生油岩样，使用热解仪进行热解模拟，制作原始产油潜量恢复系数、原始有机质恢复系数，对该盆地二叠系铁木里克组高成熟—过成熟径源岩进行恢复。结果：该盆地二叠系烃源岩原始有机质丰度不高，生烃潜力低。结论：热解模拟恢复原始有机质丰度是一个简便、快速、准确有效的恢复方法。

Selecting the immature source rock samples to simulate and making SF-Tmax Plate and CF-Tmax Plate,this paper introduces how to restore the original contents of organic matter in high-over maturated source rock from the Tianmulike Formation(P2t), Pemian in Yili Basin. The result indicates that the contents of original organic matter in the source rock from pamian in this basin are not high, Oil-generation potentiality is al-so low.
