摘    要:
提出了针对碳酸盐岩裂缝型储层的裂缝识别和类型判别方法:在对常规测井曲线进行小波多尺度分析的基础上,通过求取剩余曲线变化率,以消除岩性对测井曲线的影响,突出裂缝信号,提高常规测井对裂缝的分辨率;以岩心描述和成像测井所识别的裂缝类型为样本,以多测井参数为变量,运用主成分分析和Fisher判别等方法,建立裂缝类型的判别模型。此方法应用于胜利油区F潜山碳酸盐岩储层的裂缝类型判别,效果较好。

Abstract:
Based on the application of wavelet analysis to conventional logs, through extracting the residual logging gradient, the influence of lithology to logging curves can reduced for highlighting the fracture signs. As a results, the fracture resolution from conventional logging is improved. On the basis of core observation and description, combined with FMI information, different types of fractures are identified using geostatistics method. An identification method of fracture network is established by multi-logging parameters. The proposed identification method of fracture network has obtained good results in the application of identifying the types of fractures in carbonate reservoirs of F Burial Hill in Shengli Oil Field.
