原油显示中原油性质的对比在地球化学普查勘探方法上具有重要意义。 在这一领域内,现有的分析方法通常限于重质油份(沸点>240℃左右)的研究。对地表的原油显示来说,在大多数场合下,研究重质油份就够了。对井下采油来说,可以用通常的蒸馏方法分出其中的轻质油份,这也是容易办到的。 常常出现困难的场合是;在普查勘探中出现油浸建造,其中富含轻质油份,而缺乏合适的实验方法。在这时候重要的是要测定它们的物理性质和化学性质,要求尽可能定量地抽提出其油浸的总数量,而又不改变它的性质。
Crude oil shows the nature of the contrast between the exploration of geochemical survey method is of great significance. In this area, the existing analytical methods are usually limited to the study of heavy oil (boiling point> 240 ℃). On the surface of the crude oil shows, in most cases, the study of heavy oil is enough. For underground oil production, the light oil can be separated by the usual distillation method, which is also easy to do. Often the most difficult are the occasions where oil-immersion construction, which is rich in light oil, is lacking in appropriate experimental methods during census exploration. It is important at this time to determine their physical and chemical properties, requiring that the total amount of oil immersion be extracted as quantitatively as possible without changing its nature.
