摘要
为快速识别注水开发砂岩油藏高含水期注采优势通道,在利用SPSS软件对选取各指标的KMO值、Sig值进行检验并判断各指标相关性的基础上,运用熵权法确定各因素权重,分别计算TOPSIS相对贴近度和灰色关联贴近度,建立了判断是否存在优势通道的灰色关联-TOPSIS评价模型。利用该模型对20口井进行了是否存在优势通道识别,经现场示踪剂监测法验证,识别准确率为85%。研究结果为油田后期实施堵水调剖措施制定提供了一定依据。
In order to quickly identify the injection-production thief zones in high water cut period of sandstone reservoir developed by water injection,a Grey correlation-TOPSIS evaluation model was established to judge whether the thief zones existed.It uses SPSS software to test the KMO value and Sig value of each indicator to judge the correlation of each indicator.Then,the entropy weight method is used to determine the weight of each factor,and TOPSIS relative closeness degree and grey correlation closeness degree are calculated respectively.Afterwards,the model was applied to 20 wells and verified by field tracer monitoring method.The recognition accuracy was 85%.The method can provide certain basis for the later implementation of water plugging and profile control measures.
