摘要
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 further understand the distribution pattern of the Gaojiabian Formation in the Lower Yangtze areas and its implications for the South Yellow Sea Basin,collection and analysis of previous data,field geological investigation,and correlations of outcrop and drilling cores samples have been carried out.The results show that the source rocks in the Gaojiabian Formation are widely distributed.The yellowish green outcrops of the Gaojiabian Formation should be black before weathering.The original abundance of organic matters might be higher.The exclusive graptolites of the Rhuddanian stage have been discovered in the Gaojiabian Formation,indicating high hydrocarbon-generating potential.In consideration of the regional tectonic evolution of the Lower Yangtze areas and upon the seismic profile interpretation of the South Yellow Sea Basin,it is concluded that the Gaojiabian Formation could be a suit of excellent source rocks widely distributed with high organic matter abundance.
