多分量地震技术实用化的一些关键问题
|
摘要
针对我国陆上油气勘探开发的特点,着重研究横向各向同性介质和裂缝介质模型的地震各向异性方法理论。为了验证理论、方法及多分量地震技术的有效性和实用性,要选择合适的试验区块,设计合理的观测系统,配以关键的处理模块以保证获得高质量多分量地震剖面。在数据的处理过程中,要结合已知地质信息,提取多分量地震属性剖面配合解决常规纵波方法无法解决的问题。要充分将多分量资料的成果与常规单分量地震剖面和解释成果进行对比,利用三分量VSP或全波列测井等信息,做好多分量地震数据的解释。要充分发挥多分量地震技术的优势必须加强处理与解释一体化的应用。尤其要注意基于各向同性假设的多分量转换波地震研究,它是多分量地震技术提高实用性、实现产业化的基础,也是进行进一步地震各向异性研究的必要技术储备。
Taking the characteristics of land exploration and development for oil and gas in China into account, this paper studied the theory and methodology of seismic anisotropy for models of transversally isotropic medium and fractured medium.To validate the effectiveness and practicability of multicomponent seismic technology,people should select suitable testing site,design reasonable layout, and adopt proper data processing modules to ensure the quality of multicomponent seismic section.To solve problems that were unsolvable with pure P-wave exploration,we should extract multicomponent seismic attributes besides existing geological information. Interpretation of multicomponent seismic data should be conducted via comparing between multicomponent seismic sections and one-component seismic sections as well as utilizing 3-D VSP or full wave logging information. To fully take advantage of multicomponent seismic technology.higher priority should be given to the integration of data processing and interpretation. Special emphasis should be laid on the study of isotropy-based multicomponent converted-wave seismic. It is the foundation of practicability and industrialization of multicomponent seismic technology, and is also the necessary technical reserve for study of seismic anisotropy in future.
