三维地震资料重新处理、解释的潜力──东濮凹陷文215南块重新认识

Potential in 3-D seismic data reprocessing and interpretation: more knowledge of South Block of Wen 215 in Dongpu depression

在对东濮凹陷北部一块重新处理的连片三维资料进行精细目标解释时，在原来认为存在一个厚的盐拱的地方，解释出一个具有沙三三储层的新块。这个新块是在精细构造解释的基础上，通过与相邻已知油气区的地震反射特征进行仔细对比，并根据波阻抗反演结果而综合确定的。对比发现，盐岩与储层的波组特征是不同的，能够明显地区分开。本文强调了利用解释工作站进行三维综合解释的重要性。

A new block with Es33 reservoir has been interpreted in a place where originally was known as thick salt arch when conducting careful target interpretation for reprocessing 3-D data in successive patch in northern of Dongpu depression. Based on subtle structural interpretation,careful comparison with seismic reflection characters in adjacent known oil-gas zone and according to wave impedance inversion results,the new block has been defined with all these integrated results. By comparison,characters of wave group between salt and reservoir are different and can be clearly identified. The paper underlined the importance using interpretation workstation for 3-D integrative interpretation.
