摘要
金刚烷类化合物在燃料化石中普遍存在。由于其独特的笼形分子结构,早期研究将金刚烷类化合物运用于高—过成熟原油及烃源岩成熟度研究。综述了21世纪金刚烷类化合物在成熟度判识、原油裂解程度及混源油判识、生物降解作用程度评价、烃源岩有机相判定、硫酸盐热化学作用识别、油气运移研究及海洋溢油甑别等方面的研究进展。总结了金刚烷类化合物成因及可能的机理。由于目前金刚烷类化合物形成机理不明确,因而导致在成熟度判识、原油裂解程度确定等方面的研究成果存在一定的差异。指出加强不同类型烃源岩及原油中的金刚烷类化合物演化研究,有利于该类化合物在油气地球化学中的应用,特别有助于深层油气藏赋存深度下限研究。
Diamondoids occur in all kinds of fuel fossils.Due to peculiar cage molecular structures,diamondoids have been widely used in the maturity assessment of high mature to over-mature oils and source rocks since the 1990 s.New advancements in maturity,oil-cracking,oil mixing,oil biodegradation,organic facies,TSR,gas washing,migration,and oil spill identification using diamondoids during 21 st century were discussed.The origin and possible forming mechanisms of diamondoids were summarized.Due to the unclearness of the origin of diamondoid,the results of the maturity and oil cracking among researchers have great differences.It is suggested that research of the evolution of diamondoid in different type oils and source rocks be beneficial to their application in organic geochemistry,especially for the depth limits for the deep reservoirs.
