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。
In this paper, three-dimensional coherence technique is used to coherently process 3D seismic data in Xinchang, Dongtai and Hexindian areas. After analysis and research, it is found that the discontinuity of faults and stratigraphic features can be very low through the low coherence of 3D seismic coherence data Clearly and intuitively. The continuity of the stratigraphic features is clearly and clearly demonstrated by the high coherence anomalies of 3D seismic coherence data. Therefore, the three-dimensional seismic coherence technology has become one of the key technologies for describing the gas reservoirs in this area and is expected to be widely used.
