针对河148井区油气藏储层纵横向变化大、分布规律不清楚，常规地震解释精度低的问题，为了提高了该地区地震剖面的分辨率，搞清储层砂体的分布规律，本文利用Jason测井约束反演技术对该地区沙三段储层进行了地震资料反演前预处理、测井资料标准化校正、合成记录标定层位，初始波阻抗模型的建立与反演处理，结果显示，反演可以识别5-10 m的储集层，解决了砂体薄互层识别难的问题，获得了比较好的勘探及开发效果。

In view of great vertical and horizontal changes of oil and gas reservoir and distribution is not clear in He 148 area. The problem of low precision seismic interpretation.In order to clear up the distribution of reservoir sand body.Jason logging constrained inversion of ES3 is used in the seismic processing.This technology can improve the seismic interpretation precision in this area by pre-processing of seismic reservoir,standardized adjustment of bore log and demarcation synthetic seismogram calibration of horizons,establishment and inversion of initial wave impedance model.The results show that it can recognize reservoirs within 5 to 10 m, solve the difficult problem of the thin-bedded alternation sandbody identification and receive better exploration and development efficiency.
