储层横向预测是在少数钻井条件下,主要利用地震资料结合测井及地质信息对储层进行早期研究的投入少、见效快的方法。本文利用二维及三维地震资料对英买7─9井区下第三系底砂岩的储层分布特征、储层厚度、孔隙度、渗透率及含油饱和度进行了预测,取得了良好的效果。地震储层预测的关键是层位的精细标定及制作PIVT剖面。

The method of reservoir transverse prediction is inexpensive and effective,which is often used to makea preliminary study on a reservoir in the case of few wells available,using seismic data in combination oflogging and geological information.The paper uses 2-D and 3-D seismic data to predict the distributioncharacteristics,thickness,porosity,permeability and oil saturation of Eogene bottom sandstones in YM 7-9 wells region.The results are satisfactory.The key to a reservoir prediction by seismics is a precise demarcation of the horizon and making a PIVT section.
