摘要
地震解释不仅仅要进行构造解释,而且还要进行储层和油藏特征描述,它是一个从层位解释到油藏描述的过程,因此,应利用沉积学理论将钻井信息、地质模型与地震数据联合使用,以确定地震属性与岩石物性的关系.在这方面,法国地球物理总公司(CGG)的基于波形分类的Stratoimagic地震相分析软件提供了一个较好的研究手段.文中对该软件在BZ25-1构造的应用进行了初步总结.应用过程中,通过地震相分析给出了具有明确地质意义的地震相图,据此对预钻井区储层的发育情况进行了预测.
Seismic interpretation is not only structural interpretation, but also lithologic interpretation and reservoir characterization. As a process from horizon mapping to reservoir description, seismic interpretation should establish relationships between seismic data and rock petrophysics by combining seismic data with drilling data and geological model on sedimentology principles. The seismic facies analysis software developed by the French CGG company, Stratimagic, is based on waveform classification and a useful tool of seismic interpretation. An application of this software to BZ25 1 structure has indicated that seismic facies maps with determinate geologic meaning can be given by seismic facies analysis, by which reservoir development is predicted in the preparatory drilling area of the structure.
