摘要 三维地震相干数据分析技术是近年发展起来的一项新技术,在解释断层和识别沉积相(砂体预测)等地质特征研究方面有独特效果.为了解决埕岛油田埕北302潜山复杂断层解释和埕北凹陷沉积相分析两项问题,采用了相干分析技术对三维地震资料进行了处理,解释出了埕北302潜山区块众多次级断层和裂缝,识别出了埕北凹陷馆陶组上段沉积相、沉积亚相并预测了有利砂体,得到了满意的研究结果.本文在简要介绍三维地震相干数据体分析技术原理基础上,重点分析了该技术在埕岛油田断裂系统解释和沉积相(砂体)预测中的具体应用并展示了成果,证实了地震相干分析的技术优势以及在油田应用的广泛前景.

Abstract: 3D seismic coherency cube analysis is a new technique developed in the recent years.It has inimitable effect in indicating geologic characteristics such as fault interpretation and sedimentary facies distinction.In order to solve two problems,namely,the fault's interpretation of the Chengbei 302 Buried Hill and sedimentary facies analysis of the Chengbei Sag,3D seismic coherency cube analysis technique was adopted in the seismic cube processing in the Chengdao Oilfield.The technique interpreted a lot of secondary faults and fractures in the Chengbei 302 Buried Hill, and distinguished distributions of sedimentary facies, sedimentary sub-facies,and sand-bodies of meandering stream deposits in the Chengbei Sag.Based on the principles of 3 D seismic coherency cube analysis technique,the study analyzed the application course of the technique on explaining faults and sedimentary facies in the Chengdao Oilfield,and summarized the main results, which showed the predominance of this technique and the wide foreground applied in oilfields.
