为了探讨下扬子高家边组烃源岩展布及其对南黄海盆地的启示,开展了资料的收集整理、野外地质考察以及露头样品与邻近最新钻孔岩心样品对比。结果显示:高家边组烃源岩分布广,黄绿色的高家边组露头样品其未风化前的颜色很可能为黑色,其原始有机质丰度很可能较高;露头样品和岩心样品均显示,高家边组存在鲁丹阶的专属笔石,显示其具有较高的生烃潜力。结合下扬子区域构造演化和南黄海地震剖面解释认为,高家边组烃源岩分布广,潜力大,很可能是南黄海盆地一套较好的烃源岩。
In order to discuss the source rock distribution and its implications for the southern Yellow Sea Basin in the Lower Yangtze Gaojiabian Basin, the data collection and collation, field geology investigation, and comparison of outcrop samples with the latest drilling core samples were carried out. The results show that the source rocks of the Gaojiabian Formation are widely distributed. The yellow-green Gaojiabian outcrops samples are likely to be black before they are weathered, and their original organic matter abundance is likely to be high. Both the outcrop samples and the core samples In the Gaojiadian Formation, there is a unique lithoprinte of the Ludanian, indicating that it has a high potential for hydrocarbon generation. Based on the interpretation of the tectonic evolution of the Lower Yangtze region and the interpretation of the South Yellow Sea seismic profile, the source rocks of the Gaojiabian Formation are widely distributed and have great potential, which is likely to be a good set of source rocks in the South Yellow Sea Basin.
