在评价水淹层的系统方法还未建立起来的情况下， 研究如何充分利用油田现有的资料来评价水淹级别将是很有意义的。本文提出了一种测井解释系统， 该系统先应用普通多维模糊统计方法从油层、水层和水淹层中识别出水淹层； 然后用灰色识别方法对水淹级别进行评价。应用结果表明， 模糊统计方法能可靠地识别出水淹层， 灰色识别方法对评价水淹级别具有良好的效果 In a systematic evaluation of the flooded layer system has not yet been established, the study of how to make full use of the available data in the field to evaluate the flooding level will be of great significance. In this paper, a logging interpretation system is proposed, which first identifies the flooded layer from the reservoir, the water layer and the flooded layer by using the common multidimensional fuzzy statistical method. Then, the gray recognition method is used to evaluate the flooding level. The application results show that the fuzzy statistical method can identify the flooded layer reliably and the gray recognition method has a good effect on the evaluation of the flooded level
