本文通过大量的室内试验，建立了干酪根氧化试验和氧化产物中有机酸的分析方法。并首次对松辽盆地北部三肇地区不同类型干酪根进行研究，通过时３口井５４块岩心不同浓度有机酸浸泡液中各种离子进行检测，同时对岩石物性、孔隙结构变化特征分析与研究发现，①不同类型干酪根氧化产率具有明显的不同；③有机酸的存在对储层次生扎隙发育起着重要的作用，这些实验研究对次生孔隙成因研究有初步的认识，为今后寻找次生扎隙发育地区提供了重要的科学依据。
This article through a large number of laboratory tests, the establishment of the kerogen oxidation test and analysis of organic acids in the oxidation of the product. And the first time to different types of kerogen in the Sanzhao area in the northern Songliao Basin, through various cores in different concentrations of organic acid soaking solution of 54 wells at three wells at the same time, the changes of petrophysical properties and pore structure were analyzed It is found that ① different types of kerogen oxidation yield has obvious differences; ③ organic acids exist plays an important role in reservoir secondary gullet development. These experimental studies have preliminary understanding of the secondary pore genetic research for the future Looking for secondary development of the gap to provide an important scientific basis.
