实验初步揭示了地层水中低分子量有机酸的主要来源：①由干酪根中含氧基团的断裂产生，伴随着干酪根热演化的全过程，主要发生在成熟早期阶段；②由地下水中微生物对原油的降解及游离氧气的氧化作用产生，发生在近地表或开启程度较高，有大气降水补给的地带；③由围岩矿物中的高价元素组成的离子或化合物，如Ｆｅ￣（３＋）、ＳＯ等，与有机质之间发生的氧化一还原反应所产生，反应受较高温度控制。
Experiments revealed the main sources of low molecular weight organic acids in formation water: ① the kerogen generated by the rupture of kerogen, with the kerogen thermal evolution of the whole process, mainly occurs in the early stages of maturity; ② by groundwater microbes The degradation of crude oil and the oxidation of free oxygen occurs in the vicinity of the surface or open a higher degree of atmospheric precipitation recharge zone; ③ minerals from the surrounding rock elements of high-priced elements or compounds, such as Fe ~ (3 +), SO and so on, and organic matter occurred between the oxidation of a reduction reaction, the reaction controlled by a higher temperature.
