摘要
相干体技术是近几年才发展完善的一项用于辅助解释的分析技术,主要用于解决复杂断裂带的断裂性质和预测裂缝发育带等地质问题。通过对相干体的技术及原理的了解,选用适当的关键参数及方法,利用相干体技术预测出川东北宣汉～达县三维地震工区陆相断裂系统的分布,以及元坝三维地震工区雷口坡组碳酸盐岩岩溶裂缝发育带,识别出了该区长兴组礁滩岩性异常体的边界,理清了宣汉～达县三维地震工区陆相断裂系统的小断层和大断层间的切割关系,准确而有效地解决了常规地震解释中遇到的断裂组合问题。
The coherence cube technique which has been developed and improved in recent years is mainly applied to geology problems of complex fault zones and prediction of the fracture-developed zones.By using the coherence cube technique and proper choosing of key parameters,it is predicted that the distribution of continental fracture system in 3D seismic survey of Xuanhan-Daxian and the carbonate carst developing zones in 3D working area of Yanba.The boundaries of anomalous bodies of Changxing reef lithological geobodies are identified.The cut-out relationship between minor fault and major fault in the 3D seismic survey of in Xuanhan-Daxian.Finally,the fracture combination problems which is a big difficulty in conventional seismic interpretation has been effectively settled.
