| 摘 要： | 岩性油气藏已成为渤海湾盆地内各凹陷重要的勘探对象。笔者根据对东濮凹陷形成演化、沉积特征的研究，结合油田下洼勘探的需要，提出了断层分析法进行岩性油气藏勘探，总结出3种模式，经在多个地区应用取得了较好的效果。该方法立足于构造对沉积的控制作用和地震资料对断层的识别能力高于对砂体的分辨能力，操作简便、实用，对断陷盆地的深化勘探具有指导意义。

| Abstract: | The lithologic reservoir has been regarded as the main exploration target in Bohai Gulf basin. There are many methods for lithologic reservoir exploration, which can be grouped mainly into three types, namely geologic method, seismic method and sequence stratigraphic method. Based on formation, evolution and sedimentation property of Dongpu Depression, combined with exploration requirements, the authors developed a new method for lithologic reservoir exploration, which is called fault analyzing method. Three sorts of models were also formulated, which have been applied in many areas with good effects. The method is based on the sedimentation controlling role of the structure and the better seismic recognition capability for fault than for sand body. Being easy to operate, this method can play a great role in further exploration for rift-subsidence basins. |
