对草海盆地泥炭、柴窝堡盆地第四系沉积物以及辽河东部凹陷、胜利东营凹陷、苏北金湖凹陷等第三系烃源岩中氨基酸、脂肪酸进行定性、定量分析，并开展热模拟实验。研究表明氨基酸主要赋存于沥青中，分解后可以生成烃类气体和Ｎ２气，对过渡带气的形成可作出贡献。烃源岩干酪根和沥青中的脂肪酸含量不少，沥青中脂肪酸以一元酸为主，具偶碳优势，干酪根中脂肪酸以二元酸为主，不具偶碳优势。沥青和干酪根中脂肪酸脱羧基后产生烷烃，对过渡带气和低熟油都可作出贡献，沥青中脂肪酸是生成低熟油中具奇碳优势正烷烃的主要物源。
Quaternary sediments in the Caohai Basin and the Quaternary sediments of the Chaiwopu Basin, and qualitative and quantitative analysis of amino acids and fatty acids in Tertiary Liaohe, Dongliu, Shengli, and Jinhu sags in the northern Jiangsu, and their thermal simulation experiment. Studies have shown that amino acids mainly occur in bitumen, which can be decomposed to generate hydrocarbon gas and N2 gas, which can contribute to the formation of transitional gas. There are many fatty acids in the kerogen and bitumen of the source rock. The main fatty acid in asphalt is monobasic acid, which has the advantage of even carbon. The fatty acid in kerogen is dominated by dibasic acid and has no advantage of even-carbon. The decarboxylation of fatty acids in bitumen and kerogen yields alkanes, which contribute to the transitional gas and low cooking oil. Fatty acids in bitumen are the main sources of n-alkanes with a predominantly carbon-rich carbon content in low-mature oils.
