生物降解作用对原油中烷基萘分布与组成特征的影响
THE EFFECT OF BIODEGRADATION ON THE DISTRIBUTION AND COMPOSITION OF ALKYLNAPHTHALENE SERIES IN BIODEGRADED CRUDE OILS
摘要
Abstract
Alkylnaphthalene series are the important geochemical parameters to indicate the thermal evolution. Fourteen biodegraded oil samples from Lengdong Oilfield of the Liaohe Basin have been analyzed. The distributions and relative compositions of dimethylnaphthalenes (DMNs), trimethylnaphthalenes (TMNs) and tetramethylnaphthalenes (TeMNs) in differently biodegraded oils have been studied. The biodegradation sequence has been set up, that is, the resistant ability for alkylnaphthalene series to biodegradation is DMNs<TMNs<TeMNs. The relationship between biodegradation degree and the maturity indicators related to alkylnaphthalene series has been studied, showing that they can not supply effective maturity information for biodegraded oils. The reason is that the resistant ability for thermally stable alkylnaphthalene isomer to biodegradation is less than the thermally unstable alkylnaphthalene isomer.关键词
