在石油地质勘探过程中,时常得到许多小量的油样,这些样品或者来自小的表面渗泄,这时样品可从水潭,沼泽或河流的面上撇得,或者自岩心,油玷的表面岩石或砂子的抽提而得,要求尽可能全面地作分析以判定渗泄的来源并与已知的油储联系起来。了解一些溜出物和残渣的产量和性质的知识亦具有价值,可以取得的样品数量往往只有数毫升,对于这些小量样品的蒸溜方法已有发表。本文给出一个由这些蒸溜方法所获得的一些溜份和残渣的分析纲要,并且描述了从它们所得到的测定数据的方法,这些方法亦适用于分析小量的其他石油产品。
In the course of petroleum geological exploration, oftentimes small quantities of oil samples are obtained, either from small surfaces, where the sample can be left on the surface of a pool, marsh or river, or from the surface of a core, The extraction of rock or sand requires that the analysis be as comprehensive as possible to determine the source of the seepage and be associated with the known oil reserves. Knowledge of the yield and properties of some of the slurries and residues is also of value, with only a few milliliters of samples available, as methods for the distilling of these small samples have been published. This paper presents an analytical summary of some of the fractions and residues obtained by these distillation methods and describes the methods of determining the data obtained from them. These methods are also suitable for the analysis of small quantities of other petroleum products.
