Abstract
The distributions of the 13C NMR-measured structural-group composition parameters of the Lena–Tunguska basin crude oils were obtained. All these distributions were shown to be far from normal, many of them being asymmetric and/or bimodal. These oils exhibit a significantly lower content of aromatics than the Volga–Urals and Western Siberia oils. The principal maximum of Car distribution lies in the distribution tail areas of the other two basins. The Lena–Tunguska oils are free of fluids with low content (below 14 abs %) of n-alkyl structures. It was also demonstrated that the crude oils sampled from the basin’s two major tectonic structures, namely the Baikit anteclise and the Nep-Botuob anteclise, differ significantly from one another in the concentrations of aromatics and n-alkyl structures.

Lena-Tunguska油气盆地原油主要结构群参数的13C核磁共振数据分布规律
摘要
获得了 Lena-Tunguska 盆地原油的13 C NMR 测量的结构组组成参数的分布。所有这些分布都被证明远非正常,其中许多是不对称和/或双峰的。这些油的芳烃含量明显低于伏尔加-乌拉尔和西西伯利亚油。C ar分布的主要最大值位于其他两个盆地的分布尾区。Lena-Tunguska 油不含n含量低(低于 14 abs %)的流体-烷基结构。还表明,从盆地的两个主要构造结构,即 Baikit 前缘和 Nep-Botuob 前缘中采集的原油,在芳烃和正烷基结构的浓度方面存在显着差异。
