在油藏特性描述中,三维地震属性是补充钻井资料的重要信息。利用三维地震的高数据采样率常常能更好地描述油藏的不均匀性,并能在现场更为逼真地评估碳氢化合物。但是,在将地震属性引入储层特征描述过程时要小心。它需要透彻地了解地质模型和因储层性质改变引起的地震响应的变化。我们将在Peciko油田的例子中详述该方法。
In reservoir characterization, 3D seismic attributes are important information to supplement drilling data. High data sampling rates using 3D earthquakes often provide better characterization of reservoir heterogeneity and provide a more realistic assessment of hydrocarbons on site. However, be careful when introducing seismic attributes into the reservoir characterization process. It requires a thorough understanding of the geological model and the changes in seismic response caused by changes in the nature of the reservoir. We will detail this method in the Peciko field example.
