摘要: 在地震反射波的解释中,利用强相位对比法识别层序界面及非构造型圈闭是极不可靠的。因此,提出了波相位对比解释方法和波的振幅同相性对比原则以及波的对比解释合理性检查。针对层序地层对比及非构造圈闭的识别,应采用波相位对比法及地震多属性综合地质解释等方法。这些方法是刻画地层岩性圈闭的有效方法。

Abstract: It is unreliable that using strong phase contrast method to identify the sequence stratigraphic interface and the subtle trap during seismic interpretation. This paper proposes the seismic reflection phase contrast and interpretation method, amplitude synchronism contrast principle and rationality examination. It suggests that these methods are effective for description of stratigraphic-lithologic traps and should be used to identify them with more accuracy.

Key words: phase contrast, seismic multi-attributes, sequence stratigraphic interface, stratigraphic (lithologic) trap, method
