柴达木盆地一个可能的地震平点异常的解释与分析

在对柴达木盆地某研究区二维地震资料进行解释时,发现了一条特强振幅异常。从异常反射特征、构造和成因等方面进行了分析,并初步推测其可能由“地震平点反射异常”引起。同时,还阐述了将该异常解释为“地震平点反射异常”存在的诸多疑点。在对强振幅异常反射特征进行分析时,应用MDI技术,做了二维地震剖面烃类检测，提高了可信度。

Interpretation and Analysis of a Potential Flat Spot Anomaly

In the 2D seismic interpretation of Qaidam basin, an anomaly of strong amplitude has been discovered. This paper analyses it from its reflection, structure and forming reason, and gives a preliminary presumption that it is resulted from “flat spot reflection anomaly”. The paper illustrates many doubtful points when interpreting it as “flat spot reflection anomaly”. The authors applied MDI techniques in the analysis for hydrocarbon detection of 2D seismic data, which enhanced the reliability of the results. 
