用测井资料评价生油岩的Δ  lgR 法已比较成熟, 取得了较好的应用效果。在勘探程度相对较低、地球化学分析资料较少的地区, 用测井资料评价生油岩是完全可行的。该方法可以对单井的生油岩从质量、厚度等方面进行评价, 再结合少量的地球化学分析资料, 就可以对区域上生油岩的生油能力、质量及分布情况等作出评价。

ΔlgR method which uses the logging data to evaluate source rock has become applicable and obtained good results. At the early stage of exploration and geochemical data relatively being rare, this method has been proved complately acceptable. ΔlgR method can evaluate source rocks of a well in terms of quality, thickness, etc. Combined with certain geochemical analysis data, the capability and distribution of regional source rocks can befinally evaluated.
