- The results of well-to-seismic calibration are effective by selecting Permian igneous rock and Carboniferous double-peak limestone as the reference layers, adjusting appropriately acoustic velocity and choosing the most suitable wavelet. 利用上述方法，以哈得四油田二叠系火成岩及石炭系双峰灰岩为参考层，选取与研究区地震数据吻合性最好的子波，合理地调整声波速度，对哈得四油田的主要储层东河砂岩进行井－震标定，获得了较为理想的效果。
