【摘要】 以大芦家地区为例详细论述了复杂断块精细构造解释的方法和流程。对地震资料的选取、层位标定、断裂系统识别与组合、层位立体解释及构造成图每个步骤的方法给以具体论述,重点分析了三维精细构造解释使用的关键技术如时变子波标定技术、相干体技术、变速成图技术。在实际应用中取得了良好的效果。更多还原

【Abstract】 This paper examplized the region of Dalujia to discuss the methods and process of complex fault block interpretation.Steps about selecting seismic data,labeling subtle horizon,identificating and combining fracture system,3D seismic stereo interpretation and structure mapping were discussed in details.And the key techniques in 3D seismic tectonic interpretation,such as time-varying wavelet,spectral decomposition coherence and the varying velocity mapping technique,were also emphasized in this paper.It has great results in the practical application.更多还原
