碳酸盐岩中爆破振动信号能量局部特征的多重分形分析

摘要

根据多重分形基本理论，建立了基于盒计数法的爆破振动信号多重分形谱模型，并开发了基于C＋＋的多重分形谱分析平台。分别对碳酸盐岩中爆破地震波测试信号开展了单道、多道信号的多重分形分析，实现对爆破振动信号能量局部奇异性的精细化描述。研究成果为更好地在碳酸盐岩中应用化爆震源地震勘探方法勘探油、气资源奠定了重要基础。%According to the basic theory of multifractal spectrum,a multi-fractal model for blasting vibration signals based on the box counting method was established,and a multi-fractal spectral analysis platform based on C ++ was developed.The multi-fractal analyses of single channel signals and multi-channel signals for blasting seismic waves in carbonate rocks were conducted.The refinement of blasting vibration signal energy's local singularities description was realized.The study results laid an important foundation for better application of the explosion source seismic exploration method in exploring oil and gas resources in carbonate rocks.
