摘　　要：评价水淹层需要利用多种测井资料进行综合解释。通过对CA油田主力区块W2、W5、W8断块水淹层测井响应特征的分析研究,利用自然电位、电阻率、声波时差等测井资料,结合相关地质、生产等信息,对水淹层进行定性识别,利用双频电阻率测井技术进行水淹级别的定量评价,在W2-93井和W8-49井的现场应用取得了较好效果,解释结果与实际情况相符。Water flooded layer can be synthetically evaluated by various logging data. On the basis of the analysis of logging response features in the water flooded layers in block W2, block WS, and bock W8 in CA Oilfield, and combined with the related geologic and production information, the water flooded layers were identified qualitatively by logging data of natural potential, resistivity, and interval transit time and evaluated quantitatively by the dual frequency resistivity logging technology. The field applications in well W2 - 93 and W8 - 49 have achieved good results. And the interpretation results are in accordance with actual situation.
