目前在石油地质中,高鉄低鉄,还原硫,有机氮,有机碳五个项目是生油层研究的主要指标,是研究地球化学相以及原始有机物含量及介质氧化还原环境的依据。已往,我室虽在石油普查工作中分析过不少样品,由于对分析的地质目的不明确,因此在方法的采用、样品的处理等方面没有从石油地质的要求上来考虑,这样分析出来的数据,不一定能说明地质问题,甚至会导致错误的结论。
Currently, in petroleum geology, five items of highland barley, reduced sulfur, organic nitrogen and organic carbon are the main indicators of the study of the oil layer, and are the basis for studying the geochemical phase, the original organic matter content and the medium redox environment. In the past, although a lot of samples were analyzed in the oil census work, our laboratory did not consider the requirements of petroleum geology because of the unclear geological purpose of the analysis. Therefore, the data analyzed in this way , Does not necessarily explain the geological problems, and may even lead to wrong conclusions.
