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。
Abstract
According to basic theory of multifractal spectrum, multi fractal model of blasting vibration signal based on box counting method was established, and multi fractal spectrum analysis platforms based on C++ were developed. Multi fractal analysis of single channel and multi-channel on the test signal of blasting seismic wave in carbonate rocks were carried out, and refinement of the energy of blasting vibration signal local singularities description were got. The research results have laid an important foundation for better application of exploration of oil and gas resources in carbonate rocks by explosion source seismic method.
