通常,一些含油盆地不仅环境复杂,同时地下地质形态也相对复杂,其岩性横向变化大、构造式样众多,特别是东部拉分盆地不同断层剖面上相互切割,平面相互交织.从地震勘探应用的情况来看,较为突出的问题是构造格局的确定以及小断层解释的准确率上不高.%Usually in some oil basins,not only the environment is complex,but also the underground geological forms are relatively complicated.The lithology changes widely in lateral direction and has many structural styles.In particular,the sections of different faults in the eastern pull apart basin are mutually cut and their planes are intertwined.Judging from the application of seismic exploration,the more prominent problems are the determination of structural pattern and the low accuracy of interpretation of small faults.
