低序级断层的地震识别技术在惠民凹陷辛34断块中的应用

APPLICATION OF SEISMIC DISCRIMINATION TECHNIQUE TO THE LOW ORDER FAULT IN THE 34 FAULT BLOCK OF THE HUIMING SAG

利用提高地震资料的品质及对地震剖面不同的处理方法增加低序级断层识别的识别及低序级断层组合的呈现,系统优化低序级断层的平面组合配套技术,并将这些技术应用于惠民凹陷辛34断块低序级断层的识别与重新组合,厘清该断块地层低序级断层的分布规律,进而对各断块的边缘及油气水系统进行调整和重新认识。

In order to enhance the quality of seismic data and increase the process method of seismic profile,new geophysical approaches of discrimination of the low order faults, determination of association of low order faults and matching of plane association of low order faults are proposed. These methods are employed to study the discrimination and re-association of low order faults in the Xing 34 Fault Blocks of the Huiming Sag. As a result,the distribution regularity of small-scale faults in the area is recognized and the characteristics of the fault block are reconstructed. On the basis of detailed study,the margins and oil and water system for each fault block are determined.
