摘　　要：常规录井岩屑的地球化学分析数据连续性差,经常为几米到几十米区间内的统计平均值,指向的地层深度不准确,尤其是海上钻井取心成本高,岩心样品地球化学分析少。为了全面系统评价海上区块烃源岩的空间展布,不漏失单井的薄层烃源岩,在岩心和岩屑样品的实验室岩石物理测量分析基础上,寻找区域内固体有机质的测井响应机理,建立烃源岩评价模型,并利用该模型对文昌A、B凹陷烃源岩层段进行了评价,取得了较好效果。Continuity of cuttings in conventional mud logs was poor in the analysis of geochemical data,it was the average values from several meters to tens of meters,the depth it indicated was not accurate,especially offshore coring was expensive,the geochemical analysis on the sample was less.In order to comprehensively evaluate the space distribution of source rocks of offshore blocks single and thin layer of the source rocks was lost,it provided useful method to build the predicting models based on petrophysical experiments to find out the well log response mechanism of solid organic matter.The predicting model is used to evaluate the source rocks in Enping Formation of Wenchang A and B Sags and good result is obtained.
