生油岩中的可溶有机质是石油汀机地球化学的主要研究对象。为此,首先要选用适宜的有机溶剂将其从岩石中抽提出来,以供进行各种测试鉴定之用。目前,人们所采用的有机溶剂种类是多种多样的,既育多种单一溶剂,也有各类混合溶剂。不同的有机溶剂具有不同的物理、化学性质,用于抽提岩石中可溶有机质时,其抽提效率 Soluble organic matter in the source rock is the main research object of the geochemistry of petroleum machinery. To do this, we must first select the appropriate organic solvents extracted from the rock for identification of the use of a variety of tests. At present, people use a wide range of organic solvents, both single solvent and mixed solvent. Different organic solvents have different physical and chemical properties, for the extraction of soluble organic matter in rocks, the extraction efficiency
