摘要
本文应用三维相干技术对新场、东泰、合新场地区三维地震数据体作了相干处理 ,分析研究后发现 :断层及地层特征的不连续性通过三维地震相干数据体的低相干异常可十分清晰、直观地展示出来 ;地层特征的连续性通过三维地震相干数据体的高相干异常得到非常清楚、明显的表现。因而 ,三维地震相干技术已成为该区气藏描述的关键技术之一 ,可望得到广泛应用。
The coherent processing of 3-D seismic data in Xinchang,Dongtai and Hexingchang areas was achieved by using 3-D coherent technique. The result analysis says that the discontinuity of fault of formation characteristic may be shown very clearly by the low coherence anomaly of coherent 3-D seismic data volumes while continuity of formation characteristic is exhibited very obviously by high coherence anomaly of coherent 3-D data volumes. As a result,coherent technique of 3-D seismic data volume has become one of key techniques for reservoir description in the area. It will find its wide application.
