相干体技术在三维地震资料中的应用

三维地震相干体技术是近年来发展起来的一项新技术，在三维地震解释中应用效果独特，相干体技术研究的是三维数据体中的不连续性特征，可在三维地震解释之前，了解研究区内断层的展布情况，缩短三维解释周期，提高解释效率和精度。该技术充分利用了三维资料中每个ＣＤＰ点的信息，避免了因常规抽线解释而遗漏小断层。目前它已成为全三维地震解释中不可缺少的工具。

The Technique of the Coherence Cube in 3- D Seismic Data

The coherence cube is a newly 3-D seismic interpretation technology developing in recent years. It makes greater contribution towards 3-D seismic interpretation. By the coherent slice, interpreters may know the pattern of faults,channels and other geological abnormal body in the research zone before 3-D seismic data is interpreted. In the same time, coherence cube can help interpreters to improve the knowledge of geological body, and reduce the interpretative period of 3-D seismic data. Otherwise, the coherence cube uses all information given by 3-D seismic data, and avoids interpreters leaking little faults because of the classic line-selected interpretation. At present, this technology has become an indispensable tool in all 3-D seismic interpretation.
