关于区分生油岩和作为生油岩标志的相对数值的方法Philippi已提出过报告。区分的根据是本地原油和运移原油的分异作用。沉积物中有机质的总含量和可抽提烃类的含量,标志着这种分异作用。用以划分生油岩的相对数值是根据可抽提烃类的含量而定的。 沉积物中总有机质的测定是一个困难问题,不能根据常规的方法来处理,合理的总有机质含量并不是总有机碳含量。 测定碳的方法是根据碳氧化成二氧化碳,然后测定所生成的二氧化碳。文献中所报导的方法主要是关于有机化合物中的总碳和钢铁中碳的方法,大多是在氧气中燃烧氧化成二氧化碳的方法。二氧化碳一般用所产生气体的体积或重量测量。土壤中总碳的测量一般是用重铬酸氧化碳,然后称重所产生的二氧化碳。
Philippi has reported on a method of distinguishing between source rock and its relative value as a source rock marker. The distinction is based on the differentiation between local crude oil and crude oil transported. The total organic matter content of sediments and extractable hydrocarbons content, marking the differentiation. The relative values used to classify the source rocks are based on the content of extractable hydrocarbons. Determination of total organic matter in sediments is a difficult problem that can not be handled according to conventional methods, and a reasonable total organic matter content is not total organic carbon content. The method of determining carbon is based on the oxidation of carbon to carbon dioxide, and then the carbon dioxide generated is measured. The methods reported in the literature are mainly about total carbon in organic compounds and carbon in steel, mostly methods of combustion oxidation in oxygen to carbon dioxide. Carbon dioxide is generally measured by the volume or weight of gas produced. The total carbon in the soil is measured by oxidizing carbon with dichromate and then weighing the carbon dioxide produced.
