通过露头及井下样品地化资料，对弋阳盆地冷水坞组烃源岩进行综合评价，并结合钻井、地震、沉积相等对有效烃源岩的分布进行预测。研究表明，该区烃源岩以湖相暗色泥岩为主，有机质丰度较高，有机质类型好，主要为Ⅰ、Ⅱ1型，有机质热演化程度中等，总体达到成熟阶段。冷水坞组有效烃源岩的平面分布广泛，具有东薄西厚的特征，探区内存在三个厚度中心，最厚可达400 m。盆地资源潜力较大，贵溪次凹和桂林次凹是下步勘探有利区带。

By analyzing geochemical data of outcrop and core samples,source rocks of Lengshuiwu Formation in Yiyang Basin were comprehensively evaluated.And then combined with data of drilling,seismic,and sedimentary facies,the distri-bution of the source rocks was predicted.Study results showed that the main source rocks are lacustrine dark mudstones in the basin,which are characterized by higher abundance and better type of organic matters including mainly typeⅠand typeⅡ1 Kerogens,and a moderate degree of thermal evolution being in mature stage in total.The effective source rocks are widely distributed and have characteristics of being thin in the east and thick in the west.There are three centers of thick-ness where the maximum thickness is 400 m in the exploration area.The basin has higher resource potential.Moreover, Guixi and Guilin sub -sag are the next favorable exploration areas.
