摘要
从济阳坳陷实际资料出发,设计了浅层、中层、中深层和深层4个断层地质概念模型。对其进行了各种地震频率扫描和噪音实验,获得了不同地质条件下不同断距断层的地震响应,为利用地震资料定量识别断层级别和序级提供了依据。
The geologic models of four faults, which are separately in shallow, middle, middle-deep and deep, are designed according to the real data from Jiyang depression. The seismic responses of different throw faults in different geologic conditions are obtained after the various seismic frequency scan and noise tests were conducted, it provides the basis for using seismic data quantitatively to identify fault grade and rank.
