济阳坳陷地震勘探效果分析

对济阳坳陷地震与探井，储量关系的定量分析表明，较强的地震勘探能力是保持勘探高水平的重要基础。三维地震的应用和发展保证了近期济阳坳陷石油储量的稳定增长。与二维地震相比，三维地震有着更好的勘探效果。随着勘探程度的不断加大，对三维地震的依赖程度民不断增强，在济阳坳陷中，三维地震提供探井井位的有效年限大致在5年左右，由于地质认识水平的不断提高，对于相同的三维地震工区，随着年限的增长探井的成功率并无明显下降趋势。

Analysis of Seismic Prospecting Effectiveness in Jiyang Depression

Quantitative analyses of relations of seismic data with exploratory well and reserve history in Jiyang de-pression shows that more powerful seismic prospecting is significant foundation for maintaining high-level exploration.It is3D application and development that guarantee the stable growth of petroleum reserves in the depression in recent years.Comparing with2D seismic,3D seismic has much better exploratory effects.Therefore,3D seismic is more and more paid attention to with exploration extent enlargement.In Jiyang depression,the locations of exploration well given by3D seismic allow useful-life possible about 5years.In view of continuing growth for geologic understandings of the depression,it appears that the successive rate for exploration wells disposed is not decreasing obviously in similar3D project area with the increase of the useful-life.
