摘　　要：碳氧比能谱测井记录了很多信息 ,在生产中仅用了 FCC、C/ O、Si/ Ca等几条计数率比值曲线 ,信息量浪费很大。为了进一步利用碳氧比测井所包含的信息 ,对俘获钙计数率曲线 CAC、非弹性钙计数率曲线 IAC、地层相关曲线 FCC及总俘获与总非弹性之比 CIM1、俘获与非弹性 (3.2～ 6 .6 Me V)之比 CIM2等进行了研究。采用了 FCC与 CIM、AC与CAC、C/ O与 Si/ Ca等 3组重叠方法判别油、气、水层 ,取得了明显的效果。C/O spectroscopy logging acquires lots of information, but only a litte of which are used in production, such as FCC data, C/O data and Si/Ca data, etc.. In order to utilize more information in production, more C/O spectroscopy logging data, for example, Calcium Capture (CAC), Inelastic Calcium (ICA), Formation Correlation Curve (FCC), ratio of total capture to total inelastic deadtime corrected (CIM1), ratio of capture to inelastic (3 2～6 6 MeV) (CIM2), etc., are further studied. Three groups of overlaying curves, i.e. FCC and CIM, AC and CAC, C/O and Si/Ca are used to determine oil, gas and water beds. Good evaluation results have been obtained.
