复杂断块构造的精细解释
|
摘要
本文针对传统上把三维地震资料当作加密的二维地震资料进行构造解释的问题,提出复杂断块构造解释 的方法与流程,确立以合成记录与井旁地震道互相关包络来解决时移、相位扫描的精细标定方法,对地震资料 进行分频处理,选择优势频带对不同规模的断层成像,利用有色反演突出断层,采用多体交互解释。此方法在 GB潜山应用中取得了良好效果。
Faced with the issue traditionally taking 3-D seismic data as infill 2-D seismic data to conduct structural interpretation, the paper presented the methods and flow for interpretation of complex fault-block structure, established using cross-correlation envelope of synthetic seismograph with uphole seismic trace to solve the fine labeling method of time-shift and phase sweeping, implemented imaging of faults with different scale by using frequency-divided processing of seismic data and selection of dominant frequency, utilized color inversion to highlight faults and adopted multi-data volume to interactive interpretation. The method achieved good results when using it in interpretation of GB buried hill.
