综合利用地震、钻井、测井资料,作者对长岭断陷地层特征进行总结,并且详细分析断陷内岩性特征及地震反射特征.

Luxiang fault depression is a first-order tectonic unit of Yitong Basin. The strata in the fault depression feature in new era, multiple source, and rapid deposition. There exist many problems in conventional stratigraphic division and correlation and traditional sequence division. Based on the clear understanding of two third-order sequences of Wanchang Formation in southern Luxiang fault depression, analyzing the attributes of maximum entropy spectrum, fourth-order sequences are identified accurately. The method has many advantages such as no limit to sampling length and higher resolution to the spectra. It may be used to accurately identify the location of maximum flooding surface. Furthermore, it provides a more intuitive understanding of the characteristics of system tract and cycling within the third-order sequence.
