ON PALAEOGENE SEISMIC STRATIGRAPHY IN LANGGU DEPRESSION

摘要: 本文综合了地质、测井和地震资料,研究了廊固凹陷下第三系五种主要的地震相,指出其沉积相特征,并预测了油气勘探的有利地区。

Abstract: Firstly, five major types and distribution patterns for seismic and sedimentary facies o Palaeogene in Langgu depression were analysed with the basis of geology, logging, seismic informations. Next, the authors described the characteristics of each facies type of seismics and sedimentation,and suggested the lateral distribution of the seismic facies and sedimentary facies is of asymmetric and vertical evolution with a succession and difference. Finally, areas favourable for petroleum exploration are predicted.
