摘要

川东地区某潜高构造嘉陵江组储层为碳酸盐岩储层,其地质特征和流体分布状态具有复杂性和多变性,测井解释采用常规方法(如利用含油气饱和度或地层电阻率的变化特征)来判断流体性质往往不够准确。为了提高对流体性质的识别精度,提出了一种模糊灰关联模式识别的方法。将灰关联分析技术与模糊集理论结合起来,采用模糊相对隶属度概念对判别对象序列作标准化处理并在此基础上求取模糊灰关联度向量,然后根据最大隶属原则判别流体类型归属。将该技术用于高峰场地区储层流体性质判别与试油结果对比后发现,该技术判别结论合理,识别精度高,有一定的地质效果。
For the carbonate reservoir the Jialingjiang group in the X area,it is not always correct to identify fluid property using the conventional methods, such as the oil and gas saturation and the formation resistivity features from the logging data because of the complexity and variance of the carbonate geological characteristics and fluid distribution state.Combining the grey correlation analysis method with the fuzzy set theory,a method of the fuzzy grey correlation pattern recognition is proposed herd to determine the fluid property more precisely.Use the fuzzy relative subordination degree to normalize the sequence of the object to be identified;and a vector of the fuzzy grey correlation degree os derived.Then the identification is made by thd principle and precise compared with the production test conclusions,which have brought forward some geological effect.
