摘　　要：碳氧比测井系列是目前套管井中解释水淹层的一种重要方法。通常是利用碳氧比测井资料计算剩余油饱和度来判断水淹层 ,而本文则探讨几种新方法 ,即氯指示法、SPOR- L POR- DT重叠法、Si/ Ca- CHL R重叠法、CIM2 - HCHL重叠法 ,来提高利用碳氧比资料解释水淹层的符合率。Nowadays, carbon/oxygen logging is an important method to determine wateredout zones in cased hole. Remaining oil saturation is often calculated with C/O logging data to indicate wateredout zones. Four new methods are proposed to improve the C/O interpretation coincidence rate with the result of well testing, i.e. chlorine index, Si/Ca-CHLR overlay, CIM2-HCHL overlay and SPOR-LPOR-DT overlay methods. A case history by the methods mentioned above is given.
