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。
Three-dimensional seismic coherence body technology is developed in recent years, a new technology, the application of three-dimensional seismic interpretation of a unique effect. The study of coherent body technology is based on the discontinuity characteristics of 3D data body. Before the 3D seismic interpretation, it can know the distribution of fault in the study area, shorten the period of three-dimensional interpretation and improve the efficiency and precision of interpretation. This technique takes full advantage of the information of each CDP point in the 3D data and avoids omission of small faults due to the conventional pumping interpretation. It has now become an indispensable tool in the interpretation of full 3D seismic data.
