摘要：

为查明桂中坳陷油气生成物质基础及资源潜力，通过开展区域沉积相研究与典型剖面、钻井资料的系统分析，对桂中坳陷泥盆系海相优质烃源岩发育环境、时空展布及地球化学特征进行了研究。结果表明：桂中坳陷中-下泥盆统发育海相优质泥质烃源岩，主要分布在南丹—河池—宜州以南早期台盆相沉积中，优质烃源岩一般厚为40~200 m；烃源岩有机质丰度高，大多数样品 TOC 值大于2.0%，最高可达4.7%，原始生烃潜量大多大于6.0 mg/g；烃源岩干酪根显微组分主要为腐泥组，相对含量为38.7%～89.7%，干酪根碳同位素值为–27.80‰～–24.84‰，结合饱和烃色谱特征分析，表明其有机质类型主要为Ⅱ型；烃源岩热演化程度较高，总体处于高—过成熟阶段。桂中坳陷早、中泥盆世台盆相环境发育有机质含量高的海相优质烃源岩，可为桂中坳陷油气生成及聚集提供雄厚的成烃物质基础。

Abstract:

To further determine the hydrocarbon potential of the Guizhong Depression in central Guangxi, depositional environments, time-space distributions and geochemical characteristics of Devonian marine source rocks in the Guizhong Depression were investigated by means of systematic analyses of samples from typical sections and the application of the related drilling data. The results demonstrated that there were two suits of excellent marine source rocks in the middle and lower Devonian of the Guizhong Depression, which were mainly deposited in an early basinal facies environment south to the Nandan-Hechi-Yizhou area. These source rocks had a thickness generally between 40 m~200 m and contained abundant organic matter, most of the TOC values were more than 2.0%, with the maximum value over 4.7%. Their original hydrocarbon-generative potential (S₁+S₂) was more than 6.0 mg/g and the kerogen was dominated by sapropelic macerals relatively accounting for 38.7%~89.7%.δ¹³C values of the kerogen ranged between -27.80‰~-24.84‰. All of these combined with the gas chromatogram characteristics of saturated hydrocarbons of these source rocks indicated that their organic matter was dominated by type Ⅱ. The thermal maturation of the source rocks was relatively high, mainly in a highly- or post-mature range. In Summary, there exist excellent marine source rocks in the middle and lower Devonian basinal facies of the Guizhong Depression，and they can provide abundant organic matter for
hydrocarbon generation and accumulation in the Guizhong Depression.

Key words: Guizhong Depression, excellent marine source rock, depositional environment, geochemical characteristics, source rock evaluation
