通过对江汉盆地潜江凹陷樊参１井不同层位暗色泥岩的分析发现，二元脂肪酸在荆河镇组、潜江组普遍存在，其碳数分布范围为Ｃ９～Ｃ２３，主峰碳数多为Ｃ１５或Ｃ１６。与一元脂肪酸的特征不同，二元脂肪酸不具偶碳优势特征，而且在垂向上也没有变化。进一步分析得知：二元脂肪酸的前身物是植物碎屑，其成烃机理为二元脂肪酸在强还原环境下加氢醇化脱水形成相同碳数的一元脂肪酸，然后一元脂肪酸再进一步转化为正烷烃。
Based on the analysis of dark mudstone in different layers in Fanqeng-1 well in Qianjiang Sag, Jianghan Basin, it is found that the Binary fatty acids are widespread in Jinghezhen Formation and Qianjiang Formation. Their carbon distribution ranges from C9 to C23, C15 or C16. Unlike monofatty acids, dibasic fatty acids do not have the advantage of being an even-carbon and do not change in the vertical direction. Further analysis showed that: Binary fatty acid precursors are plant detritus, the hydrocarbon generation mechanism of the binary fatty acids hydroperoxide dehydration in a strong reduction environment to form the same carbon number of monobasic fatty acids, monofatty acids and then further transformed into n-alkanes .
