摘要
在讨论了多重分形理论后,结合地震多重分形的存在性、可行性等问题的分析,针对灰岩裂缝带地震记录特征,研究了适于研究区灰岩裂缝地震多重分形检测方法.在所研究方法中,针对以往地震记录离差、求和、极值等分形测度存在的问题,设计了能够揭示地震变化的全信息分形测度刻划方法.同时对窗口函数的选取、配分函数计算中的幂次的选择及拟合计算问题进行了讨论.在理论模型验证方法正确合理性的基础上,研究了实际资料的应用.应用结果表明:1)多重分形计算结果是保幅的,并且能够揭示地震振幅异常信息;2)对较小断层甚至是裂缝带在相干体等一般技术方法不能识别这一问题上,得到了较好地解决,并通过多口井资料证实了所解决问题的有效性和效果.
In the discussion of the multifractal theory,combining with seismic multi-fractal existence,the problem such as the feasibility analysis,aiming at the characteristics of seismic records of a limestone fracture belt,suitable for the study area of limestone fracture seismic fractal detection method.In the research methods,the seismic record deviation,summation,extreme value of fractal dimension measurement problems,design can reveal the seismic changes in the whole information fractal measure evaluation method.At the same time window function is selected,the partition function in the calculation of the power selection and fitting calculation problem are discussed.In the theoretical model verification method is correct and rational foundation,studied the actual data application.The application results show that: 1) multiple fractal calculation result is amplitude,and can reveal the seismic amplitude anomaly information;2) the smaller fault even fracture zone in coherence and general technology and methods cannot identify the problem,has been solved,and through wells data it is proved that the solution to the problem is effectiveness and efficiency.
