1.有机碳丰度——有机碳是地质体中碳链化合物的总称。但不包括一氧化碳、二氧化碳、碳酸盐、金刚石、石墨等无机碳。有机碳丰度即有机碳含量的多少,它可直接用来代表地质体中有机质的丰富程度,也是评价生油潜力的重要指标之一。 2.可溶有机质——指可以用有机溶剂(如氯仿、苯、甲醇等)从沉积岩中抽提出来的那部分有机质。不同的溶剂抽出的可溶有机质的质量可能不同。在有机地化中常将氯仿抽提物称为“氯仿沥青A”,它是衡量岩石中有机质质量的基本参数。
1. Organic carbon abundance - Organic carbon is a generic term for carbon chain compounds in geological bodies. But does not include inorganic carbon such as carbon monoxide, carbon dioxide, carbonate, diamond, graphite. Organic carbon abundance is the amount of organic carbon content, which can be directly used to represent the abundance of organic matter in the geological body, but also evaluate the potential of oil production is one of the important indicators. 2. Soluble organic matter - The portion of organic matter that can be extracted from sedimentary rocks with organic solvents (eg chloroform, benzene, methanol, etc.). Soluble organic matter extracted by different solvents may vary in quality. Chloroform extracts are often referred to as “chloroform bitumen A” in organic geochemistry and are the basic parameters for measuring the mass of organic matter in rocks.
