地层、岩性油气藏地震勘探方法与技术
|
摘要
针对地层、岩性油气藏地震勘探方法与技术这一论题,本文从几个特定角度展开了简要的讨论。首先给出了应用地震勘探技术进行地层、岩性油气藏勘探的基本思路;然后围绕怎样得好一个三维数据体,研讨了应引起高度关注的八个在地震数据采集时及十个在地震数据处理中的问题;第三是论述了地层、岩性油气藏勘探地震数据处理与解释的技术系列,包括地震数据反演技术、属性分析、岩石物理分析、地质建模和地震正演模拟技术;最后讨论了地震数据的综合地质解释。文章并没有对地层、岩性油气藏地震勘探方法与技术进行全面和系统的介绍,而是针对上述四个方面阐述了作者对相关方法与技术的认识和体会。作者认为所述问题对应用地震方法勘查地层、岩性油气藏有实际意义。
This paper discusses a few specific points on seismic exploration for strati-lithologic reservoirs.Firstly we review the general idea of seismic technology for strati-lithologic reservoir identification.Secondly 8 issues of seismic data acquisition and 10 issues of seismic data processing are illuminated in order to obtain a good 3D data cube.Then a set of interpretation approaches for strati-lithologic reservoirs are demonstrated including seismic inversion,attribute analysis,petro-physics analysis,geologic model building,and seismic forward modeling.Finally we conclude comprehensive geological researches on seismic data.The author's observations are given and these could be meaningful for strati-lithologic reservoir identification.
