摘要
地震资料具较好的横向分辨率，而测井资料纵向分辨率高，若将二者有机地结合起来，就可以大大提高地震储层横向预测的效果。本文采用测井约束反演的方法，对东营凹陷永63块Es3^中油藏砂体展布特征进行了研究，最终预测的砂体厚度不仅井点处具有较高的精度，而且其展布趋势也与地质分析相吻合，从而为正确认识该地区Es3^中油藏砂体分布特征提供了依据，对该区的新井部署具有一定的指导意义。
Seismic data has good lateral resolution, and log data is high in vertical resolution. If combining both of them, the seismic prediction of lateral reservoir can be greatly improved. By using a method of log_constrained seismic inversion, the sandbody distribution of Es M 3 reservoir in Yong 63 block is studied. The eventually predicted sandbody thickness is very accurate in well points, and its distribution tendency is identical to that from a geological analysis. These results can offer a basis for correctly understanding sandbody distribution of Es M 3 reservoir, and may be a guide to drilling new wells.
