摘要
本文介绍了相干体技术在地震勘探方面的突破和Geoprobe软件的三维可视化相干体技术在宋芳屯油田芳231区块的应用,利用沿层雕刻透视相干体分析相邻近地震道的相干性,进而识别小断层和分析构造地质。通过实际效果分析可以看出,Geoprobe软件三维相干体技术是一种更有效识别断层解释的方法,可以提高解释精度,同时对油气藏分布具有一定的指导意义。
In this paper,it mainly elaborates that the seismic exploration has nearly made a new breakthrough in the seismic data interpretation with the 3D visual coherence cube technique and Geoprobe software system based on the study of coherence cube technique carries out in fang231 block of Songfangtun oilfield,with the probe curved along horizon,we can explore small fault and analyse the geological structure by analyzing the similarity of seismic signal between adjacent trace on the seismic cub.By analyzing and the actual effect,we may find coherence cube technology is an available fault's interpret method.It can improve the interpretable precision,and it also play a guided role in the oil-gas reservoir.
