多尺度分形参数在裂缝检测中的应用研究
APPLICATION RESEARCH OF MULTI-SCALE FRACTAL PARAMETERS TO FRACTURE DETECTING
【摘要】 根据地震波的动力学参数对裂缝敏感性和裂缝的分形特征,以地震层位振幅数据为基础,应用分形理论的裂缝检测方法(多尺度分形参数的地毯覆盖方法)对裂缝进行检测。这里用计算机生成了Mandelbrot集的分形图案,用多尺度分形参数进行了检测,效果显著。用该方法对某油田的层位振幅数据进行了裂缝检测,检测结果清楚地反映了裂缝的分布状况。
【Abstract】 In view of the dynamics parameters of seismic wave being sensitive to fractures and the fractures being of fractal characters, this paper presents a method to detect formation fractures using fractal theory on seismic amplitude data. First, a fractal pattern of Mandelbrot set is produced using computer and the pattern is detected by multi-scale fractal parameters with a ideal result. Then this method is applied to detect formation fractures for a field seismic amplitude data and the result clearly shows the distribution of fractures.
