加氢催化裂解技术作为近年来新发展起来的有机质大分子裂解技术,专门应用于大分子中共价键结合小分子的释放。本研究探索该技术应用于含油气沉积盆地高演化油气源岩原生有机质提取的可能性。以塔里木盆地下古生界油气源岩为例,选取了障壁泻湖相、欠补偿盆地相、闭塞欠补偿陆源海湾相、灰泥丘相等四类典型潜在源岩进行了加氢催化裂解实验,结果表明,加氢催化裂解产物中正构烷烃与甾烷的分布特征与上述源岩相完全吻合,证明加氢催化裂解实验可以有效地提取高演化油气源岩的原生有机质,为下一步实现该技术应用于油气源的对比奠定了基础。
Hydrogenation catalytic cracking technology as a newly developed organic macromolecule cracking technology in recent years, specifically applied to the release of covalent bonds with small molecules in macromolecules. This study explored the potential of this technique for the extraction of primary organic matter from highly evolved hydrocarbon source rocks in hydrocarbon-bearing sedimentary basins. Taking the Paleozoic hydrocarbon source rock in the Tarim Basin as an example, four typical potential source rocks, barrier lagoon facies, undercompensated basin facies, occluded undercompensation terrestrial source rocks and plaster mounds, were selected for hydrocracking experiments. Results The results show that the distribution characteristics of n-alkanes and steranes in hydrogenation catalytic cracking products are completely consistent with the above-mentioned source rock facies. It is proved that the hydrocracking experiments can effectively extract the primary organic matter of high-evolution hydrocarbon source rocks. The comparison of oil and gas sources laid the foundation.
